Risø HDRL services:

Calibrations are carried in accordance with the recommendations given in the report CIRM 29 (Guidelines for the calibration of dosimeters for use in radiation processing). Link to PDF file.

1. Irradiation of dosimeters and samples to specified doses. Irradiations are carried out at the Risø HDRL cobalt-60 gamma-cells, at a 10-MeV electron accelerator or at the Risø HDRL 100 keV electron accelerator.

2. Calibration of dosimeters by irradiation of the dosimeters at the user’s facility together with HDRL reference transfer dosimeters.
Risø HDRL reference transfer dosimeters are
- dichromate solution in ampoules
- alanine pellets and films

3. Issue of calorimeters for routine or reference dose measurement at the user’s electron beam facility. Risø HDRL supplies the software CalDose for dose measurement with calorimeters.

4. Dosimetric validation of irradiation facilities for Installation and Operational Qualification (IQ – OQ) in accordance with the requirements in the international standard for radiation sterilization EN ISO 11137-1:2006.

5. Measurement of dose distribution in products for performance qualification (PQ) in accordance with the requirements in the international standard for radiation sterilization EN ISO 11137-1:2006.

6. Risø B3 radiochromic dosimeter film for dose mapping.

7. RisøScan – software for dose measurement with radiochromic dosimeter film and an office scanner. [Link to Risø HDRL website]

8. Other dosimetry equipment
- aluminium wedge for energy determination at electron accelerators,
- phantoms for irradiation of dosimeters at gamma and electron accelerator facilities.

9. Courses on 
Validation and Process Control for Low Energy Electron Beam Irradiation 

Validation and Process Control for Electron Beam Sterilization
