Coming up in a lightning deal later today is your very own Geiger Counter with inbuilt Data Logging and a USB charge and Data Interface to your PC.
Visiting Chernobyl (they did), in fear of Putin/Trump/Fukashima, etc, etc now you can watch out for radiation in real time.
Standard price is £94.00 it will drop for a while today!
I truly thought these were only industrial and laboratory tools - who remembers them in school in the '70s when you could handle mild radiation sources or poke mercury around the desk.
