1pcs of SBT10 geiger counter

Details:
The SBT-10 is a Geiger-Muller tube containing 10 separated detectors, and a huge mica window which allows detection of u03b1, u03b2 (hard and soft) and u03b3 radiation. Basically it for soft beta radiation by datasheet. The STB-10 tube is designed to be operated in various PROFESSIONAL radiometric devices. It has very HIGH SENSITIVITY (efficiency of registration) in comparison to other counters.
Designed for registration of beta radiation with energy from 0.156 MeV

The counter has 10 similar anodes used in SBM-20. The overall measurement efficiency is at least 5 times greater than SBM-20.
