TECHNICAL SPECIFICATIONS
Radiological Characteristics
• radiation detected: alpha >2 MeV, betaEmax >100 keV, gamma and x-rays from 5 keV to 1.3 MeV • detector: end window GM tube, 1,5-2 mg/cm2 • MICA window active surface area 15,2 cm2 • measurement range: surface contamination 1 to 100 000 cps or 0.01 to 1 000 000 Bq/cm2 • alarm levels: freely adjustable alarm levels for contamination level • cps linearity: ±15% ±1 digit over the range.
