OB-SERVO LA/D

OverviewThe LA/D type irradiator is a Category II. Secondary Standard Lab (SSL) unit. The sealed source is stored in fully shielded position when the equipment is not operating. The shielding of the irradiation room is made of normal concrete by the End-User.

OperationThe source is placed in a special drawer in the centre of the equipment. The biological shielding of the equipment is made from lead. A pneumatic system hoists the source during operation. The standard collimator provides a horizontal beam which can be attenuated by different lead layers.

The operation and control of the facility is accomplished automatically by a PLC system.

ApplicationThe irradiator is suitable for research and calibration tasks. The equipment can be utilized mainly for calibration of detectors and other radiation protection units. The high dose rate also allows investigations in the field of material science.
