The SBM-20-1 Geiger-Muller counter is designed to detect hard beta and gamma radiation in radio engineering devices
Geiger-Muller counter SBM20-1 ionizing radiation sensors are intended for use in household radiation monitoring devices. They have low supply voltage, high speed and excellent output signal parameters. The case is made of stainless steel with a thickness of 50 microns. Geiger counters respond to hard beta and gamma radiation.
SBM-20-1 is equivalent to SBM-20, STS-5, SI22G
