RADIATION MONITORS AT1125 AND AT1125A

Portable high sensitive radiation monitors intended to search and detect gamma radiation sources, measure ambient gamma radiation dose equivalent rate and alpha and beta radiation flux density from contaminated surfaces and estimate ¹³⁷Cs specific activity in environmental samples

Features

- Multifunctionality
- High sensitivity
- Fast response to radiation background changing
- Wide-temperature operation under field conditions
- Built-in LED stabilization system of the measuring path providing no need to use a reference source
- 256-channel MCA
- Special large backlit LCD
- Alarm at threshold exceeding
- Logging and transfer measurement results to PC
- Keeping up to 100 measurement results in the instrument memory
- Scrap metal radiation monitoring
- Specific activity measuring under field conditions as an option
- Three power types

Application

- Search, detection and location of radiation sources
- Scrap metal radiation monitoring
- Radiation monitoring of the environment, area, targets and materials
- Dosimetric and radiometric monitoring at industrial enterprises
- Monitoring of contamination fluctuations
- Radiometric control of ¹³⁷Cs in agricultural products under field conditions
- On-site radioactive monitoring of mushrooms and berries

The main function of the radiation monitors AT1125 and AT1125A is to search, detect and locate gamma radiation sources and measure ambient gamma radiation dose equivalent rate from near-background levels. The instruments are high sensitive and have fast response to slight radiation background changes due to using scintillation NaI(Tl) and at the same time they provide accurate dose rate measuring in the wide gamma radiation energy range because of the correction function 'instrument spectrum - dose' in 13 intervals of the whole energy range of 0.05-3 MeV. The radiation monitor AT1125A has scintillation NaI(Tl) as well as a G-M tube, which extends greatly ambient gamma radiation dose equivalent rate measuring range. The instrument can be connected to the external smart probe BDPS-02 providing alpha and beta radiation flux density measuring from contaminated surfaces and also ambient x-ray and gamma radiation dose equivalent rate and dose equivalent measuring. The radiation monitors can have an optional operation mode of ¹³⁷Cs specific activity monitoring in liquid and granular samples under field conditions.
