RDS-80 表面污染仪Surface Contamination Meter

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, easy to use design

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 possibility for abnormal contamination levels.

The functions comprise contamination measurements with alarm functions ａnd automatic conversion to activity value ａnd additionally surface contamination measurement with a possibility to store the histogram events into the meter′s internal memory （external accessories required for downloading the data into a PC via IrDA port）.

Physical 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 measurement range: surface contamination 1 to 100 000 CPM or 0.1 to 1 000 000 DPM* alarm levels: freely adjustable alarm levels for contamination level CPM linearity: ±15% ±1 digit within the range of 200 to 100 000 CPM the DPM display is calculated from CPM values by multiplying with

Isotope coefficient

Functional characteristics display in either CPM or DPM surface activity DPM display configurable for different nuclides activity 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
