EPD™ Irradiator IRR-1

Thermo Scientific™ EPD Irradiator IRR-1 checks the constancy of performance of individual Electronic Personal Dosimeters. It permits verification/calibration check of EPD radiological performance in the field. It also gives confidence that an EPD is performing within design specification.

• Easy-to-operate,compact benchtop unit requires no special shielded facility
• Compatible with both EPD Mk1 and MK2
• Allows large numbers of dosemeters to be processed quickly, easily and with no radiation risk to the operator
• When the IRR-1 is used in conjunction with the Thermo Scientific EPD Maintenance Database software, records can be maintained for the calibration of individual EPDs

Irradiator Performance

• 15 to 25°C (59 to 77°F) 95% confidence level
• Am-241 60 keV γ: Statistical accuracy better than +2% (irradiation time 2 min.); systematic positional error of better than 2%
• CI-36 714 keV β (Emax): Statistical and positional accuracy better than +10% (irradiation time)
