Uses chlorine-36 and americium-241 sources to deliver beta and gamma radiation for a predetermined time and with excellent repeatability for an individual EPD.
- 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
