Descripción

Operating principle

Irradiator based on the use of radionuclide sources of 137Cs.

The installation scheme is realized with a fixed irradiator and linear-positioned platform of calibration bench.
The range values ??of dose rate of gamma radiation is achieved by using different sources of 137Cs with different activity and changing in the distance "a source-detector".

Sizeof the radiation field varies by distance "a source-detector" or diameter collimator channel.
The positioning of calibrated equipment in the collimated gamma beamis provided by the calibration stand.
Management function of the stand is carried out by means of software and portable control panel.
