The Rados Dosimeter Irradiator has been designed for calibration of the Rados TLbased dose control system.
The instrument is used for sensitivity calibration of the system, for system linearity checking and for individual sensitivity calibration of the TL-material in use.
The Irradiator is microprocessor controlled and uses stepping motor for controlled irradiation of the dosimeter pellets.
During the irradiation process the pellets are continuously moved below the source in order to provide precise and equal dose for each individual pellet.
The drift of exposure of individual pellet in one dosimeter card is negligible.
A source of Sr90 is used to give standard doses of app. 1mSv.
The irradiator may be programmed to give linearly increasing dose steps for checking the system linearity.
The actual dose may be varied by repeated irradiations.
