Radioactivity is a part of our planet. It has existed from the very beginning and it exists today. It is everywhere – in the food we eat, the water we drink, and the air we breathe. This naturally occurring radioactivity can be detected in our bodies as well – in our bones, muscles, and tissue. But, it’s man-produced radioactivity that we fear most. A Geiger counter is a device that detects and measures ionizing radiation, the most harmful kind of radiation on our planet. 

We think that we are the undisputed rulers of this planet firmly in control of our environment. However, Chernobyl and Fukushima disasters remind us how suddenly things can get out of control. Not to mention small viruses like COVID-19 who know nothing about our power and authority. 

Do I Need a Geiger Counter?

Well, I can’t answer this question for you. The truth is that if we wanted to cover all possible SHTF scenarios, we would end up with more gear than we can store. So, we need to prioritize. The need for a Geiger counter depends on perceived radiation hazard levels. 

I’d say that if you live anywhere near a nuclear plant, it is a good idea to have one (just ask the people from the town of Okuma where the Fukushima power plant is located). While I don’t believe in the possibility of a nuclear war, the threat of nuclear terrorism is real and possible. But, it also depends on where you live.  

Today’s Geiger counters are more accurate, more affordable, and much more compact than they used to be. It makes them available and easy to carry and store. You can pack them into your bug out bag (BOB) without taking up much space. Truth be told, I wouldn’t keep it in my BOB all the time. I would store it somewhere else and add it if there’s a nuclear accident or a significant nuclear hazard.

If a nuclear accident happens, this gadget suddenly becomes vital. It will tell you how bad it is, how much protection your shelter provides, and when it’s safe to relocate.

But, at the end of the day, it is your call. If you want to add a Geiger counter to your equipment, here are some of the best models.

It is a Geiger counter, but it can also measure EMF (electromagnetic field) levels in your home, nitrate levels in your food, and water quality (levels of dissolved solids). It’s an impressive 4-in-1 device. You can monitor radiation levels and radiation doses. While it’s a little bit bigger than typical hand-held Geiger counters, it is also very accurate.

A Geiger counter is a cool device even if it’s not a top-priority survival item. However, in the case of a nuclear disaster, it would become irreplaceable. It’s also not a bad idea to check out your home and your working environment occasionally. Sometimes we are exposed to slightly higher levels of radiation even if we don’t know it. So, if you want to be fully prepared, you might want to have one of these gadgets. 

Hopefully, you will never have to use it in a nuclear disaster scenario, but if it ever happens, this device can make the difference between life and death. In the meantime, you can monitor your environment and the food you eat.
