RDS-80 Radiation Survey Meter

For Surface Contamination

Rados RDS-80 Survey Meter

The RDS-80 Surface Contamination Meter is useful in different fields of radiation protection. It is used in the nuclear industry, medical field, research, emergency response, and other operations involving a possibility for abnormal contamination levels. This digital, pocket, pulse rate Meter is suitable for personnel who need to locate and detect contaminated surfaces and objects. The functions include contamination measurements with alarm functions and automatic conversion to activity value. Additionally, it is possible to store the histogram events into the meter´s internal memory. The use of CSW software is required for downloading the data into a PC via IrDA port.


Wide measurement range: up to 100 000 cps or 100 000 Bq/cm2
Standard surface contamination measurements in cps or Bq/cm2
Contamination measurements with histogram function
Visual and audible alarms
Lightweight and user-friendly
Software for parameter setting, histogram readings and nuclide calibration

Technical Specifications

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
