Alpha-Beta Probe

Alpha-Beta Probe

The Radiological Detection System (RDS) Alpha-Beta Probe is used for the measurement of surface contamination survey meter of both alpha and beta radiation. It has dual detection capability, having both a phosphor scintillator and a zinc sulfide PMT. The probe can discriminate between Alpha and Beta simultaneously. Designed and tested for military ruggedness to meet both military/defense requirements and industrial applications.
