Gamma radiation monitoring plant УДГ-АТ130 / UDG-АТ130 is designed for testing and calibration of radiation-monitoring equipment in a collimated beam of gamma radiation.
The plant is based on using 137Cs radionuclide sources, additionally 60Co and 241Am.
The plant implements a scheme with a fixed exposure irradiator and linearly positioned calibration bench platform.
Range of gamma radiation dose rates is achieved by using 137Cs sources with various activity and various "source - detector" distances.
The size of radiation field is varied by the "source - detector" distance or by diameter of collimator channel.
Positioning of measuring means in collimator radiation beam is provided by the calibration benchmark.
Control of the plant automated functions is performed remotely by operator.
• Standard collimation assembly in accordance with GOST 8.087.2000
