The RDS-30 is a geiger counter based on a GM-tube and is a survey meter for gamma radiation detection measurement H*(10). Calibrated towards Cs-137 (662 keV). It’s designed for applications involving a possibility for abnormal radiation levels. Compact, lightweight, waterproof make the RDS-30 well suited to radiation survey in field conditions.
