Portable dose rate alarm unit, specially designed for personal radiation protection when handling ionizing radiation.
GRAETZ GammaSmart two
Description
The GammaSmart two device is a very robust, pocket-sized, battery-operated dose rate warning device for personal radiation protection
It detects gamma and X-ray radiation and reports these with clear optical and acoustic single pulses, which increase in the pulse sequence as the dose rate increases
The splash-proof aluminum housing (IP54) provides shielding against electromagnetic influence, an optical battery control indicates the operational readiness of the device
A plastic clip is used to attach the dose rate warner to clothing
Optional:
- GammaSmart two V40 with a dose rate warning threshold at 40 µSv/h for use in non-destructive testing (NDT) radiographic testing. For mobile handling, the local dose rate must not exceed 40 µSv/h.
