Description
The GI-01H gamma irradiator, when fitted with appropriate radionuclide sources, and optionally equipped with an attenuator set, serves as a reference source of homogeneous collimated gamma ray beam ranging from some tenths of μGy/h to Gy/h. This type of equipment is normally used in metrology laboratories for the calibration of gamma dose rate and dose meters.
Key Features
– Irradiator for one Co-60 radionuclide source
– Provides homogeneous collimated beam with dose rate up to Gy / h
– Low dose rate on the irradiator surface
– Fully automated irradiation process
– Integrated safety system
– ISO 4037:2019 complaint collimator
– The sources do not rotate in the transport system
Purpose
The GI-01H gamma irradiator, when fitted with appropriate radionuclide sources, and optionally equipped with an attenuator set, serves as a reference source of homogeneous collimated gamma ray beam ranging from some tenths of μGy/h to Gy/h. This type of equipment is normally used in metrology laboratories for the calibration of gamma dose rate and dose meters.
The GI-01H Gamma Irradiator consists of:
– a lead shielded rotating container for one Co-60 radiation sources,
– a beam collimator,
– a control unit,
– safety and alarm systems.
The irradiator and other components are fully remotely controlled from a host PC, which has the DARS Data and Control Software installed.
When irradiation is commenced, the source is lifted to the collimator opening and the irradiation begins.
The collimator meets the requirements of ISO 4037:2019. Lead is used as standard material for the collimator. Optionally, tungsten can be used.
The irradiator is fitted with a safety system that ensures irradiation stops in the case of emergency.
In case of a power failure the exposed source drops into the shielded position by gravity.
