I'm thinking about buying a Geiger counter, I'm not an expert so I don't really know what Geiger counter I/we should buy.


any advice is welcome

Hi Pashalis, they have been flying off the shelves do to the panic.....some companies ( and there are many many vendors) that sell them have run out of inventory, and there is a back log of orders yet to be filled with no new orders being taken at this time. Good idea? Why not, it seems to be something that will continue to be a handy item for future events. ;) the second pic. is mirth.

The Radalert 100:(geiger counter)
The Radalert 100, our most popular product, is a general purpose geiger counter. It measures alpha, beta, gamma, and x-radiation. Its digital display shows readings in your choice of counts per minute (cpm) or mR/hr, up to 100,000 cpm or 100 mR/hr, or in accumulated counts. A red LED blinks and a beeper chirps with each count (the chirp can be muted). An audible alert sounds when the radiation reaches a user-adjustable level. This geiger counter meets CE certification requirements for Europe.
