1 This practice outlines irradiator installation qualifica-tion, operational qualification, performance qualification, and routine product processing dosimetric procedures to be fol-lowed in the irradiation of blood and blood components by the blood-banking community. If followed, these procedures will help to ensure that the products processed with ionizing radiation from gamma, X-rays (bremsstrahlung), or electron sources receive absorbed doses within a predetermined range.
2 This practice covers dosimetry for the irradiation of blood for these types of irradiators: self-contained irradiators (free-standing irradiators) utilizing Cs, Co or X-rays (bremsstrahlung), teletherapy units, and electron accelerators. The absorbed dose range for blood irradiation is typically 15 Gy to 50 Gy. In some jurisdictions, the absorbed dose range for blood irradiation is 25 Gy to 50 Gy.
3 The energy range is typically from approximately 40 keV to 5 MeV for photons, and up to 10 MeV for electrons.
4 This practice also covers the use of radiation-sensitive indicators for the visual and qualitative indication that the product has been irradiated.
