RDS-80A Contamination Survey Meter

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 • 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 Functional Characteristics : • display in either cps or Bq/ cm2 • surface activity ( Bq/ cm2) display configurable for different nuclides • cps follow-up by audible signal with frequency proportional to activity • visual and audible alarm: user settable for surface activity • histogram capability of up to 480 points with user settable logging interval • backlit display with six large digits • built-in self diagnostics • gamma background reduction for Bq/ cm2 measurements • Built-in infra-red port ( IrDA) Electrical Characteristics: • power supply: 2 alkaline batteries IEC LR6/ AA size ( recommended) • battery life time: at least 2000 hours at normal background with alkaline cells • ( more than 1 year under normal operation) • battery alarm: two-step alarm for low battery voltage • electromagnetic compatibility: CE compliant Mechanical Characteristics : • rugged plastic case • dimensions: 78 x 126 x 57 mm • weight: 280 g without batteries, 330 g with batteries Environmental Characteristics : Temperature range: • -25...+ 55° C operational ( -13... 131° F) • -40...+ 70° C storage ( -40... 158° F) • protection level IP67 ( temporary immersion / floating device
