RDS-80 Surface Contamination Meter
Portable Survey Meters
TECHNICAL SPECIFICATIONS:
Radiological Characteristics
• radiation detected: alpha >2 MeV, beta
Emax
>100 keV, gamma and x-rays from 5 keV to 1.3 MeV
• detector: end window GM tube, 1,5-2 mg/cm
2
• MICA window active surface area 15,2 cm
2
• measurement range: surface contamination 1 to 100 000 cps or 0.01 to 1 000 000 Bq/cm
2
• alarm levels: freely adjustable alarm levels for contamination level
• cps linearity: ±15% ±1 digit over the range. The Bq/cm
