This fun science kit is designed to excite and engage experimenters of all ages in re-creating the development of the first light […]
Analog Geiger Counter
MAKE contributor John Iovine has been designing and improving affordable Geiger counters for decades. After Japan’s nuclear crisis last spring, his company was swamped with orders.

This analog counter detects beta radiation above 36 kilo-electron volts (keV) and gamma above 7keV, signaling each radioactive particle detected with an […]

What forms does it take? How can it be converted […]
