Best Radiation Detectors Buyer’s Guide

Radiation is an extremely serious thing to deal with if you fear that you have been potentially exposed to radiation or there is an area where you think radiation is building up, using a detector can be an easy way to measure that the radiation is at a safe level.

With something as serious as radiation, it can be daunting to know what to look for when buying a detector.

You want to ensure you buy a good one so that you and your loved ones are protected, however it can be difficult to know exactly what makes a good radiation detector. 

That’s why we’ve put together this handy guide to help you. The detectors that we’ve looked at in this article are some of the best on the market but if you still aren’t sure there’s no need to worry.

Read on for all the important information you need to know when shopping for a radiation detector.

We’ve even included an FAQ section to help answer any questions you may have. 

Digital or Analog

The first major choice you will encounter when buying a radiation detector is whether to buy an LCD or an analog reader.

An LCD detector will display the readings on a digital screen, whereas an analog reader will display the data on a basic screen.

You will most likely choose a digital LCD screen as this is what we know in the modern age, the screen will likely resemble your cell phone’s screen and this will provide you with some security. 

However, if you are more of an old-fashioned individual you may opt for an analog device. Neither one is better than the other, it is all down to personal preference.

The important thing is that you buy a device that you are comfortable with and one that you can read easily. You should consider both options and buy the one that you think will work best for you. 

Accuracy in Results

You may encounter the screen first, but by far the most important thing to look for when buying a radiation detector is accuracy.

The only thing with shopping for accuracy is that you will be unable to tell how accurate the device is until you can actually use it.

To shop for accuracy, you should pay a lot of attention to the reviews of the device you are considering buying.

You should not dive headfirst into a purchase as this could lead to you buying an inaccurate device, instead, you should do a lot of research.

Read the reviews that other people have left for the device you are interested in, paying attention to their experience with the accuracy of the device. 

As well as looking at the reviews, another great way to tell if the device is accurate is by looking at the reputation of the company the product is manufactured by.

Companies do not gain a good reputation by manufacturing poor goods, so as long as you are buying a device from a company with a good reputation, the device should provide accurate information. 


The final thing you should consider when purchasing a radiation detector is versatility.

Radiation is not made up of a single ray, instead, it is a build-up of multiple rays from different areas and all these rays will likely be different times of radiations.

Some forms of radiation can be a lot more dangerous than others, so for optimum safety, you should buy a radiation detector that can identify more than one type of radiation. 

With something as serious as radiation you want to know exactly what you are dealing with, the risks associated with it, and possible causes of the radiation.

A lot of radiation detectors will be able to do just this, providing potential causes of the level of radiation measured in your home.

Versatility will be more important depending on the situation you are measuring radiation in so you should consider your situation and buy a device accordingly
