Geiger Counters are essential to have if you think you may be at risk of radiation poisoning. This article will cover the different types, reviews, and more to give you a head start.

Best Geiger Counters

Nuclear warfare is probably the worst disaster imaginable. If you look at the sheer size of the dangerous weapons the world has, you will pucker up quickly. Many countries have these weapons, and some countries aren’t necessarily good friends with the United States. 

Luckily, we have a military built like no other, which has allowed us to be significantly protected thus far. However, war can break at any time, even if things seem to be going in a great direction. 

Nuclear bombs, when detonated, cause an enormous explosion at the detonation site, which after the fact, causes a large amount of fallout to fall from the sky. The topic relevant for today, though, is radiation. 

Nuclear bombs leave an extraordinarily large amount of radiation behind after detonation, which is deadly if you absorb too much of it. However, it can still cause severe long-term side effects; even if you absorb a little of it. 

If you have a bunker and plan to ride out this wave of toxicity, you’ll need to make sure it’s safe to exit the shelter. This is why Geiger Counters are critical to have if you want to play it safe after disasters. Let’s get into it.

Types Of Geiger Counters

Portable/Stationary

If you’re like most people looking for a Geiger Counter, you’re likely going to buy a portable one. These are handheld and frequently are compact enough to fit in the pocket. Some Geiger Counters can detect one type of radiation or many.

They’re typically used acutely for short amounts of time and are powered by batteries. However, if you are looking for one of them to stay active long term, a stationary Geiger Counter would be best. 

Stationary Geiger Counters are often powered via USB, meaning they can stay powered on for long periods. The performance of both types are pretty similar, so it comes down to personal preference.

X-Ray Detectors

Some Geiger Counters can detect X-Ray radiation. This type of radiation is rarer to run into than the other types of radiation listed here, but if you are exposed to high enough levels, it can lead to severe illnesses. 

Gamma Detectors

Like X-Ray radiation, Gamma radiation can also penetrate through the thickest walls, carrying similar harmful effects as X-Ray radiation, leading to various illnesses. Luckily, Gamma is easily detected with Geiger Counters that have this detection built-in.

Beta Detectors

More common than X-Ray and Gamma radiation, Beta radiation is roughly 8,000 times smaller than the others, making it a hazardous type of radiation. It is typically blocked by walls or another solid object, but if it comes into contact with the skin, it can cause extreme injuries like skin burns.

Alpha Detectors

This type is by far the least dangerous type of radiation typically detected by Geiger Counters. It does not travel through solid objects. Alpha radiation is very unlikely even to penetrate the skin. It can, however, be swallowed or get into any wounds, at which point it could lead to minor or severe injuries, depending on your luck.

Soeks Quantum Professional Radiation Detector Dosimeter Two Geiger Counter Tubes

Probably the most sophisticated Geiger Counter on this list, the Soeks Quantum is one to have if you’re serious about radiation detection. This Geiger Counter features a sizable colored LCD screen with a plethora of useful features. 

This Geiger Counter, however, is best-used stationery. It is excellent to use around the home or other locations at risk of radiation and placed there long-term.

How To Use Geiger Counters

Turn It On

If you’ve already got a Geiger Counter and you’re ready to start using it, the first step is to turn it on. If you have a portable one, you’ll likely need to place a few batteries inside. If it is a stationary type Geiger Counter, you may need to plug in into a power or USB outlet.

Set It Up

If you have a Geiger Counter device with an LCD screen, you may be required to set it up. Many also have logging systems that need to be set up before you test for radiation to record and save the data. It may also make you do tests to ensure that it is working correctly.

Refer To User Manual

Each type of radiation is different, so refer to your user manual regarding what your particular Geiger Counter results mean. However, the higher the scale goes, the more radiation there is in met cases.

Start Using It

To start, walk to the area you’d like to check for radiation and wave the Geiger Counter near the particular area or item you’d like to check. You’ll need to listen for clicks or watch the LCD screen to determine how much radiation there is. 


Frequently Asked Questions

How Accurate Are They? 

This varies widely to each Geiger Counter due to the quality and spectrum of radiation types that the Geiger Counter detects. 

Many of them are used for non-emergency purposes, so they are not entirely accurate. Keep in mind, handheld Geiger counters will not hold a candle to those used by our military, but they are valid enough for the average user. 

I think it’s okay to expect around 50% accuracy, although this, as said before, can vary widely. These Geiger Counters are undoubtedly good enough for most situations and will let you know if danger is prominent.

Why Should I Have One?

Geiger Counters are great for anyone preparing for any SHTF scenario or for those of you who want to be prepared for more common disasters like Hurricanes. 

Although rare, equipment malfunction can emit a dangerous amount of radiation that you may not even know is there, affecting you long-term. 

They are also great for those of you who work around equipment or material that has a possibility of emitting radiation.

Which One Is Best For Me?

This mainly comes down to personal preference, although other factors do come into play, such as which features it includes.

If you use the Geiger Counter for portable uses such as work or disaster scenarios, then any portable one that covers most radiation types like Beta, Gamma, and Alpha would probably suit you best. 

However, if you plan to use it as a long-term device to alert of radiation in or around your home, then a stationary Geiger Counter would likely fit you best, plus many stationary Geiger Counter pick up more types of radiation.


Verdict

Geiger Counters are, in my opinion, critical to have if you are a prepper or work around materials that pose a radioactive risk. Radiation can pose a severe threat to any living thing and can cause illnesses like skin burns, loss of consciousness, cancer, and much more. 

They come in different sizes and uses, some better for particular kinds of radiation than others. They’re typically easy to use, although you should make sure that you read the user manual well so you’re able to judge the conditions without risking injury due to misuse. 

The Military often uses Geiger Counters during operation that poses a risk of radiation poisoning. They’re even used by adventurers traveling into Chernobyl, a city in Russia that has very high levels of radiation due to a nuclear reaction mishap within the town.
