Specification :

The RDS-80A Surface Contamination Meter is a versatile contamination detector which has been designed for a wide range of applications in different fields of radiation protection in nuclear industry, rescue and other operations, involving a potential for abnormal contamination levels.

Features

• wide measurement range: up to 100 000 CPM or 1, 000 000 DPM
• standard surface contamination measurements in CPM or DPM
• contamination measurements with histogram function
• visual and audible alarms
• handy and easy to use design
• software for parameter setting, hitogram readings and nuclide calibration

Specification :

Radiological Characteristics :
• radiation detected: alpha > 2 MeV, beta > 100 keV, gamma and x-rays from 5 keV to 1.3 MeV
• detector: end window GM tube, 1, 5-2 cm2; MICA window Ø 4.4 cm ( 1.74� )
• measurement range: surface contamination 1 to 100 000 cps or 0.01 to 100 000 Bq/ cm2
