Details:
The SBT-10A is a Geiger-Muller tube containing 10 separated detectors, and a huge mica window which allows detection of α, β (hard and soft) and γ radiation. Basically it for soft beta radiation by datasheet. The STB-10A 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
