Geiger counters -or called merely as radiation detectors- are used to detect and measure the radiation level in a particular area or object. Through the Geiger–Müller tube, ionising radiation such as alpha particles, beta particles and gamma rays are detected. Geiger counters are handheld devices, but they can help you become aware of the amount of radiation contaminating the objects inside your house and around your surroundings.

Due to human intervention and other activities, a lot of places in the world have already been contaminated with radionuclides. You might not notice it, but these ionising radiations can be found in common household items such as paint, rock collections, granite flooring, and even on metal spoons and ceramic dinner plates.
With all the Geiger counters out there, it’s not easy to choose which one can accurately detect the type of radiation you have in your area. That’s why I have come up with some tips to help you pick the Gieger counter that will work best for you.
1. Accuracy
The accuracy of any radiation detector or Geiger counter depends primarily on the built-in detector of ionising radiation. There are two types of two types detecting methods used by radiation detectors: the Geiger–Müller tube which can detect alpha, beta and gamma radiation and the “pancake tube” which better detect beta and gamma radiation but not as reliable when it comes to detecting alpha radiation.
2. Display
Make sure you get a Geiger counter that has a clear and highly readable display. All the information are essential, so you should be able to see every detail on the screen.
3. Purpose
Geiger counters are small handheld devices, but they can cost a lot. Before buying one, you have to be clear on what to do with it. Whether it’s for personal or educational use, the purpose of obtaining one can help you in choosing the right Geiger counter for you.
Those are just some of the things that should be taken into consideration when buying a Geiger counter, but there are still a lot of factors that you should take note of – and that depends on the reason you’re planning to buy one. Nonetheless, you will surely find the Geiger counter that will fit your needs perfectly. With that said, here are some of the best and most effective Geiger counters you can get on the market today.
