Radiation Monitor
Atomtex АТ1125 and AT1125A portable, highly sensitive Radiation Monitors designed to search and detect sources of gamma radiation, measure ambient gamma radiation dose equivalent rate, alpha and beta particle flux density from flat contaminated surfaces, as well as for radiometric monitoring of radionuclides in samples using a beaker.
The Atomtex АТ1125 and AT1125A are equipped with NaI(Tl) scintillation detectors of high sensitivity and are able to rapidly respond to minor changes in the radiation background. “Spectrum-Dose” correction functions in an energy range from 0.05 to 3 MeV, which allows for highly accurate dose rate measurements in a wide range of gamma energies. Apart from the scintillation detector, the AT1125A Radiation Monitor is equipped with a Geiger-Muller tube (Geiger Counter) that significantly expands the range of ambient gamma radiation dose equivalent rate measurement. These devices allow for sample radiometric radionuclide content monitoring with lead protecting unit indoors and express-testing in field environment without lead protecting unit. Users may opt for an external BDPS-02 detection unit which allows for measurement of alpha and beta particle flux density from contaminated surfaces.
Features:
- Field operation capability over a wide temperature range
- Integrated system for measurement path LED stabilization
- Threshold level crossing alarm
- Memory function for up to 100 measurement results
- Writing, storing and transmitting measurement data into PC via RS232 or USB (adapter) interface
