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 � 4.4 cm ( 1.74� )
� measurement range: surface contamination 1 to 100 000 cps or 0.01 to 100 000 Bq/ cm2
� alarm levels: freely adjustable alarm levels for contamination level
� cps linearity: ± 15% ± 1 digit over the range. The Bq/ cm2 display is calculated from cps values by multiplying with Isotope coefficient
