How To Do Sutures


Below are two great YouTube videos that show two different ways of suturing up a wound.





Looks pretty simple to me. You can probably find some foam type fabric to practice these techniques on.

4 Ways To Make An Ionized Radiation Detector



As ISIS continues to move into Europe and Asiatic countries, they will gain access to materials that emit ionizing radiation. Aging nuclear power plants, aging missiles, and radioactive dumps all pose a threat to our health and well being without even being in the hands of an enemy nation or terrorist group.

That's why you need a reliable means to detect nuclear radiation on a routine basis, and you can even build yourself such a device, as an alternative to store bough Geiger counters.

Here's what you need to know about different ways to build an ionizing radiation detector and how much it will cost to operate and maintain the equipment.

Radiation Types - The Difference Really Counts

Ionizing radiation comes in 5 basic forms. For the sake of simplicity, it is easiest to rate them by what they can and cannot pass through. Ideally, you should be able to detect at least alpha and gamma rays, as they span the range of particles you would need to be most concerned about as someone trying to survive a nuclear event.

Alpha

Alpha carries the least amount of energy. It can be stopped by a sheet of paper. These particles are still very dangerous if swallowed or inhaled. Even alpha particles are the easiest to stop, they are also some of the hardest forms of ionizing radiation to detect. Typically, it will take a conventional Geiger counter to detect alpha particles. There are some DIY explorers that claim they are able to detect this form of radiation with modified photo diodes and transistors.

Beta

These particles carry more energy than Alpha particles. They can be stopped by aluminum foil, thin boards of wood, and other fairly lightweight material. Beta particles can also be very dangerous if swallowed or inhaled.                                     

You are more than likely familiar with these particles because they are routinely used in medical imaging studies. As with other forms of ionizing radiation, they are derived from unstable atoms that break apart and release rays of energy. X-rays cannot penetrate bone or thicker metal plates.

Typically, even the thickness of most metal pendants is enough to stop X-rays from passing through. Some talcum powders and other body powders can also stop a good percentage of X-rays from passing into the body.

Gamma

Of all the radiation types that can be released by a nuclear power plant, a nuclear bomb, or from nuclear waste, gamma rays are the most dangerous. They carry a good bit of power and can only be stopped by lead, iron, or other metal shields. Gamma rays can be detected readily enough by photo diodes and other alternative ionizing radiation detectors.

Worst comes to worst, this is the form of radiation you should be most concerned with detecting. If you know there is gamma radiation present, and can track the changes in the amount, then you can estimate when beta and alpha particles will also be gone.

Neutrons

Since this is one of the three main parts of an atom, it is also one of the most dangerous because other atoms can absorb it and become unstable.  Once the host atom becomes unstable, it can also release radiation, or become “radioactive”.  Neutrons can only be stopped by large amounts of water, concrete, or other substances that contain a large amount of hydrogen.

Bear in mind, however, these substances will also become unstable and release radiation to some extent. Overall, it is not easy to detect neutrons. Fortunately, relatively few are released from an atomic explosion when compared to other particles.
                                          


Pros and Cons of Making a Conventional Geiger Counter

Modern electronics has made a lot of advances in terms of changing from vacuum tube based technologies to solid state devices. Some forms of ionizing radiation still require a vacuum tube and high voltages.

While a Geiger counter is still the most reliable device for detecting the widest range of radiation types, it can be very expensive to make.

The vacuum tube can be damaged by incorrect voltages, or need to be replaced for other reasons. Since this is also the most expensive part of the detector, it is fairly easy to see why most people don't try to build, let alone maintain a conventional Geiger counter for use on a routine basis. 

How to Use Arduino or Cell Phone to Make a Geiger Counter

Building a Geiger counter with Arduino isn't so different from building anything else. You will need to start with a main board and then add the appropriate sensors and output devices. With Arduino you have the choice of using a gas tube like a regular geiger counter, or you can use a solid state version.

Build the tube version (choose a dosimeter/geiger counter kit that has the LCD shield and tube bundled with it) and keep it on hand for situations where you suspect there is a need for detecting all particles emitted by a nuclear event. You may also be able to use conventional tubes that weren't originally designed for use with an Arduino board. Just make sure that you know their voltage requirements and how to test if they actually work.

There are many tubes available from different countries. As a result, you will need to do some research on each tube and learn from people in forums dedicated to building various kinds of Geiger counters.

You can also build the version that relies on a solid state sensor. This one is sturdier and uses less power. You can simply set up nuclear watch stations that report around the clock.  I would also recommend adding an additional board to the Arduino main board that will accommodate a memory chip.

This will enable you record sampling data around the clock so that you can upload it to your computer and compare it over time. As you learn what the normal radiation levels are in your area, you can always set the sensor to beep or give some other type of alarm when the levels are too high.

You can also try adding an wireless remote system or even one that will report directly to your smart phone. If you live near a nuclear power plant, or any other area that houses any kind of radioactive material, it is very important to have these kinds of records so that you have a better sense of what is going on around you.

For an even simpler and cheaper option, you can purchase a solid state radiation sensor that will plug into the sound jack on your cell phone. As with Geiger counter tubes, there are a few different models available. Take some time to study the apps that control them so that you can find one that meets your sampling and data recording needs.



Kearny Fallout Meters

Of all the ways to detect radiation, the Kearny Fallout Meter (KFM) is one of the cheapest and simplest. If you don't know how to maintain the meter, it can produce some unreliable results.  In order to make this meter, you only need some tin foil, a tin can, some paper, charging wires, and a means to give a static charge to the foil leaves. Make a Gamma Radiation Detector Using a Photo Diode

Making a radiation detector using a photo diode will cost about the same as using an Arduino kit. The advantage to building it using this method is you will have complete control of all the parts. Once you have the main elements figured out, you can also look for ways to convert from solid state parts to ones that will better withstand an EMP.



The Tin Can Ion Chamber Radiation Detector 

If you choose a sensor to add to your cell phone, it will only cost around $30.00, while a good Arduino system may cost as much as $150.00. Building  your own conventional Geiger counter could cost several hundred dollars by the time you purchase the tube, build the power supply and other supporting parts.

There are some down and dirty ways to build a radiation detector for under $10.00 with items from around your house. While there are several videos and DIY forms that claim these radiation detectors work, it may be hard to test that out and get viable answer.



Unlike the Kearny Fallout Meter that has a long history of validation, other forms of tin can radiation detectors may or may not work as described.
If you are on a tight budget and want something to start with, here are the basic steps.

To start off, you will need a metal can (soda cans work well) with an interior that conducts electricity; some tin foil, a 4.7K ohm resistor, some wire, a 9 volt battery and attachment clip, a multi-meter, and an NPN  transistor. 

You can also use any transistor that is over 1.0 K ohm. If you are scavenging for parts, or included them in your bug out gear, variable resistors may also be good to start with. Since this meter is highly susceptible to false readings caused by electromagnetic fields (even if you move around or change body position, the meter numbers will change), you may be find a different resistor setting works for different occasions. 

There are two main kinds of solid state transistors; PNP  and NPN. If you scavenged a transistor, it is very important to make sure you have the right kind, and also that it is still in good working order. You can use the ohm setting on your multi-meter to achieve both goals. 

Once you are certain that you have a suitable transistor, you can begin assembling the radiation detector. Make sure the top of the can is open. 

Next, drill a hole in the center of the bottom of the can. Pull the leads of the transistor apart so that they do not touch each other. Solder some wire onto the collector and emitter leads. Make sure that the wires never touch each other or the can.  Transistors can be shorted out very easily if the leads cross or anything that extends from them. 

Solder bare wire to the base lead of the transistor and then stick it through the hole that you drilled in the bottom of the can. The bare wire should reach to the opening of the can, but not touch the tin foil. The wire for the transistor emitter connects to the negative lead for the battery tester. 

The collector lead should be connected to the negative lead for the battery. Take one side of the diode and solder it to the outside of the can. 

The other side of the diode connects to the positive lead on the multi-meter and the positive side of the battery. In order to reduce stray electromagnetic impulses from impacting the sensor, you will need to cover the open part of the can with tin foil.

To operate the meter, attach a 9 volt battery to the adapter and turn on the multi-meter. Start off with the highest voltage setting so that you don't inadvertently short out the meter. 

Later on, once you know the circuit works, you can use a lower setting so that you get a more accurate reading.

To test the meter, you can try purchasing radioactive rocks. Just make sure you know how to store them properly so that you do not inadvertently wind up with radiation poisoning.

There are also a number of kits available that have limited amounts of radioactive material in them. If there is gamma radiation present, the meter will show a much higher reading than it will for electromagnetic interference or background radiation.

As with any other DIY project, you will need to experiment with different materials so that you are accustomed to seeing what sets the meter off and whether or not you need to be concerned about it.

In these challenging times, there are many ways and places where you and your loved ones may come into contact with ionized radiation. 

If you want to limit your exposure, know when to bug out, or even know whether the area is contaminated, being able to test for radiation is very important.

While you may not be able to afford a conventional Geiger counter, there are several less expensive alternatives. This includes making your own Kearny Fallout Meter, as well as an ion detection chamber.

As you improve your skills with building electronic devices, you can try building a detector that uses a photo diode as the main sensor, or better yet, a detector that uses an Arduino board and compatible output devices.

Regardless of the method you choose to start with, it is very important to test each device out and practice with it as often as possible. 

This will make it much easier to be confident of your findings in both nuclear emergencies and situations where the truth about increased ion radiation levels in your area is being hidden from you.

Measure Distance Using Compass





Your compass is a measuring tool that can be adapted to a variety of needs. As shown here, it can be used to measure more than just direction.

You can use your magnetic compass to determine the width of a stream or small body of water without having to get wet. This quick and easy method of determining distance using a compass may just come in handy. In any case, it is always a good trick you can use to amaze your fellow survivors.

Here is how it is done.

1. Standing at the edge of the water, sight an object directly across from you on the far bank. Take a compass reading on this object and mark the spot where you are standing.

2. Walk along the stream until the compass reading to the same object across the stream changes by 45-degrees and mark this spot also.

3. Now measure the distance between the two marks you set. This will be equal to the distance between the first mark and the object you sighted across the stream.

For example:

Say you are standing next to a stream and directly across from you on the opposite bank is a large tree. Take out your compass and sight the tree. 

Let’s pretend the compass reads 300-degrees (Azimuth type compass) or S30W (Quadrant type compass). Mark this spot and then walk either downstream or upstream until the compass sighting on the same tree reads 45-degrees in either direction from your first reading (either 255-degrees or 345-degrees on an azimuth type compass, S15E or N15W on a quadrant type compass). 

Mark this position also. The width of the stream is equal to the distance between your two marks on the ground. If you have practiced pacing (and every survivor should) you can count the number of paces between the two marks and calculate the width of the stream.

The best survivalists are skilled in using whatever materials at hand in novel ways that give him an edge over his environment. "Thinking out of the box" is a trademark of the true survivor.

Reloading and Other Unique Survival Skills



Urban Survival Skills received this question from BlackHat16: "I want your opinion on reloading equipment. I want to buy, maybe spread out due to the cost, a reloading setup in case shit hits the fan I can reload ammunition as I believe it will be hard to come by. What versions of reloading equipment would you recommend and any other recommendations on equipment would be appreciated."

Mr BlackHat16, I would have to ask several questions before I get into reloading presses and ancillary equipment. Have you any experience in reloading? Do you plan on stocking reloading supplies, such as powder, primers and bullets? In a SHTF scenario, I would think that reloading supplies such as primers, powders and bullets would be as or more scarce than ammunition.

I think having reloading equipment and more important, the experience in reloading would be a good survival skill, in fact a mandatory skills, but much lower in priority that say, wilderness survival skills, farming and canning skills and others, simply because of the requirement of having the components - powder, primers and bullets, not to mention empty cases (brass). However, if all other survival material and equipment needs are met, having some reloading equipment would be a good idea.

Lyman hand press, single stage press, rotary (aka Progressive) presses could provide a capability, again given the components, to produce good quality ammunition, given the skill, and/or be a barter item in the coming crunch. If pushed, you could make a usable powder, re-manufacture spent primers and cast bullets, but you need some equipment, material and skill to do so.

I am NOT trying to dash your thoughts of getting reloading equipment just know that it can be overwhelming for a novice re-loader and most preppers may be better served using the required money to invest in ammunition, firearms or other higher priority survival equipment and items. All reloading presses or tools requires dies for that cartridge. Please go to YouTube and research reloading - plenty of people willing to help there.

A hand tool, such as the Lyman 310 hand-tool, is like a pliers type of re-loader and the cheapest route you can go. See the picture. You need the Lyman 310 and a set of dies for whatever caliber/cartridge you want to reload. The benefit in this method is the small, portable package. Go to Lyman Products to see their Lyman 310 and other reloading equipment.





http://www.lymanproducts.com/index.php/

A single stage reloading press like the RCBS Rock Chucker is a quality piece of equipment, not so portable!, but user friendly, just requires the changing out of dies for each step in the reloading process, so it's slow. See one of the RCBS single stage presses in the picture.


Going to the RCBS website and look at their equipment and kits is a good idea.

http://rcbs.com/Products/Presses-and-Kits.aspx



Likely the best reloading products come from Dillion Precision. Mike Dillon, the founder, just passed away this past November, but he left a legacy that won't be beat anytime soon. He revolutionized the reloading industry with his dynamic progressive presses which is about as automatic of a reloading setup as you can get. You can go to their website, but don't leave without requesting their Blue Press Catalog.

https://www.dillonprecision.com/




One overall good distributor of reloading equipment would be MidWay. They offer a lot of products and have good prices and service. Go to their site here:

Is George Orwell's 1984 Coming True?


" Here is a good article I just read. Its getting to get real...."

Urban Man-


In February 1937, an idealistic and ungainly Englishman in his thirties traveled to Spain to take his place in the trenches at the Aragón front to defend the Republic. His name was Eric Arthur Blair, remembered by history as George Orwell. This month, 80 years after the start of that adventure, Richard Blair, the writer’s only son, now a 72-year-old retired agricultural engineer, visited Huesca to take part in the opening of a major exhibition about his father.

Talking to EL PAÍS during his brief stopover in Madrid on his way back to London, Blair evoked the figure of Orwell and commented on the relevance of his legacy and the enormous interest in his final novel, 1984, which has become an international best-seller since Donald Trump became US president.

“It’s true that in recent weeks, with the references in the United States to ‘alternative facts’ [cited by Kellyanne Conway, one of the president’s top advisors], there has been increased interest in his book. But my father has never gone out of fashion.” The book was not so much a prophecy as a fable about Nazi and Stalinist totalitarianism, says Blair, although as he points out, some details from the novel that once seemed like science fiction have been part of our everyday life for some time, such as security cameras that watch our movements, or what some companies know about us from our internet activity, or how we use our credit cards. “Society has evolved toward what he saw. The world is becoming Orwellian,” he says.

Blair is patron of the Orwell society, a not-for-profit organization dedicated to spreading knowledge about the life and work of the writer, as well as debate about ideas, and that remains scrupulously neutral about politics. Which might explain why he is so careful in choosing his words when talking about Trump.

“I think that there is a lot of tension and compression in the White House right now. It is true that Trump is attacking the press, but he is a complete enigma, they are all maneuvering and learning to live with each other,” he says.

Nevertheless, he says he cannot help but be happy at the hike in sales of his father’s books, particularly as he inherited the publishing rights (“which expire in 2020,” he points out). But he recognizes concerns that this has been due to the public finding parallels between the current situation and the dystopia Orwell described.

Orwell and his wife Eileen adopted Richard in 1944. Ten months later, Eileen died on the operating table. Some of the friends of the tuberculous-stricken writer suggested that he give up custody of the child but he ruled out the possibility. The relationship between Orwell and his adopted son became closer when the two of them moved to the Scottish island of Jura, chosen because it was a healthier location for Orwell to overcome his illness and where it was so cold that “if you move six feet away from the fireplace, you freeze.”

Blair’s memories from those days are of a loving father who made wooden toys, who had a strange sense of humor, and whose parenting style had none of the political correctness of modern upbringings. On one occasion he allowed the three-year-old Richard to smoke from a pipe filled with tobacco collected from his cigarette butts. The result, aside from a vomiting fit, was that the child saw himself temporarily vaccinated against the vice of smoking.

It was on Jura that Orwell finished 1984, writing in his room during the day and spending the evenings with the child. One of their favorite activities was fishing, especially for the lobsters that filled out a diet otherwise made frugal by post-war rationing. One weekend in August 1947, however, on a journey back from a weekend of relaxation on the west side of Jura, their boat sank and they almost drowned. Blair says Orwell’s health suffered as a result. David Astor, owner of The Observer newspaper, which published the writer’s work, asked to be allowed import the newly discovered antibiotic streptomycin from the United States, with which he was treated between December 1947 and July 1948 in a hospital near Glasgow. But his efforts were in vain: Orwell developed an allergy to the medication. “His nails fell out and blisters appeared on his lips,” Richard recalls. The writer died in January 1950 at age of 46, when his son was about to celebrate his sixth birthday.

What is the most important lesson that Orwell taught us? For journalists, says Blair, there are many. “To be honest. The most important things are facts which can be corroborated, not reality as you want it to be. Journalists today do not have time to check facts, and errors are perpetuated and multiplied on the internet until they become true.” The writer’s son also recalls Orwell’s six rules for clear writing from his 1946 essay Politics and the English Language. “Never use a metaphor, simile or other figure of speech that you are used to seeing in print; Never use a long word where a short one will do; If it is possible to cut a word out, always cut it out; Never use the passive where you can use the active; Never use a foreign phrase, a scientific word or a jargon word if you can think of an everyday English equivalent; Break any of these rules sooner than say anything barbarous.”

Blair finished up with his father’s definition of liberty: “If liberty means anything at all it means the right to tell people what they do not want to hear.”

Blair is particularly concerned about the lack of dialogue in contemporary society. “All people do is shout at one another, without actually listening.” And he is surprised to see young people who, instead of speaking face to face, spend all day staring into their smartphones. “Even couples in restaurants! Are they communicating with each other via text messages?!” he jokes. And what would Orwell make of the 21st century, the era of the internet, great scientific advances and post-truth?

“Ah, now that’s the million-dollar question. But it’s impossible to get into anyone’s head. Nor to come up with the answer by reading his books. If he were still alive he would be 113, and would have had a lot of new influences… There’s no point in speculating.” As such, we don’t know, and we can’t know. But he does go as far as to assume one thing: whatever his thoughts, they would be characterized by common sense.
