Radiation Detection Kit
Ideal for Emergency Response
The DSM-506 Emergency Kit features the digital DSM-506 Survey/Scaler meter which detects most alpha, beta, and gamma contamination fields. Sensitivity ranges from background to 2000 mR/hr. The DSM-506 utilizes an internal energy compensated G-M detector for high range. External probes include the pancake G-M probe (model HP-265) and a high sensitivity tissue equivalent scintillation probe (MRSP-1). The meter measures in dose or cpm, which can be switched from the front panel. The timed count scaler function provides more accuracy in low level contamination measurements. Digital display, auto-ranging and diagnostics are a user-friendly improvement over the older analog systems. Other components of the system include a 1 micro curie cesium check source. All components of the system are contained in a durable hard case for easy storage and portability.
