Best Portable Geiger Counters [Amazon Best Sellers]

Here you have the list with best portable Geiger counters, all handheld, affordable and easy to use Amazon bestselling items. The term Geiger counters describes gadgets designed for detecting alpha particles, beta particles, and gamma rays.

Perhaps you might want to know that alpha particles are doubly ionized helium nuclei. Beta particles are high-speed electrons or positrons. Gamma rays or gamma radiation is a short wavelength and highly penetrating electromagnetic radiation which is created in the radioactive decay of atomic nuclei, so these are energetic photons.

These instruments are sometimes called Geiger-Muller dosimeters so just to know that this term describes the same type of items. All in all, these are versatile items which you can use to detect a variety of harmful radiation types and particles. You might want also to check our separate list with best portable radiation detectors.

Many items in the list are Amazon Prime items so you can have them shipped for free and in a couple of days. Some of them are also on sale and you can save some money. So here they are, please have a look:
