Metrology - Irradiators

An irradiator (or "calibrator") is the heart of a calibration laboratory. It is the source of radiation for calibration purposes and houses the radiation source. The typical sources are either an X-ray tube or isotopes emitting different types of radiation.

A high-end irradiator can accommodate up to 8 different isotopes, which allows a divergence of the possible calibration qualities and dose rates.

The main task of an irradiator is the safe storage and shielding of the sources while the irradiation is not active, and the collimation and safe movement of the sources while the irradiation is activated remotely from the control room.

PTW and VF use only carefully tested elements and systems to reduce the risk of malfunction to an absolute minimum. Redundant safety loops are installed in each laboratory to immediately stop the irradiation and move the source to the safe position if there is a possibility of exposure of personnel.

Below you will find typical equipment for each laboratory, sorted by the type of radiation source for your individual requirements. We support you in complementing existing laboratories or in opening a new turnkey laboratory, which will be tailored to your needs and requirements by our specialists.
