Description
Overview
GAOTek portable radiation containment meter is a portable surface contamination monitoring equipment. The apparatus utilizes thin plastic scintillator detectors with ZnS coating, can be fixed for mobile use and directly or indirectly detect the surface contamination of alpha and beta ( wipe test samples ) radiation sensitively, lightweight,and easy to use.
Features
- Thin-layer plastic scintillator detector, not gas filling
- Large detection area up to 170cm2
- Simultaneously measure the alpha and beta radiation, no need of external probe
- Alarm threshold adjustable continuously.
- 25 freely programmable nuclides library, user-specific nuclides may be added
- Background subtraction
- Measurement time of background adjustable
- Large area LCD display with illumination
- Result display in CPS, Bq or Bq / cm2
- User-friendly interface, 4 key operation by one hand
- Light weight, measuring settings protected by pass code number
