1.1 This practice outlines irradiator installation qualificationand dosimetric procedures to be followed in the irradiation ofblood and blood products by the blood-banking community. Iffollowed, these procedures will help to ensure that the productsprocessed with ionizing radiation from gamma, bremsstrahlung X-raysor electron sources receive absorbed doses within a predeterminedrange.
1.2 This practice covers dosimetry for the irradiation of bloodfor these types of irradiators: self-contained dry-storage137Cs or 60Co irradiators (free-standingirradiators), teletherapy units, self-contained bremsstrahlungX-ray units and electron accelerators. The absorbed dose range forblood irradiation is typically 15 Gy to 50 Gy.
1.3 This practice also covers the use of radiation-sensitiveindicators for the visual and qualitative indication that theproduct has been irradiated.
1.4 This practice is intended for use by technically andnon-technically oriented people. It, therefore, contains moretutorial information than many other ASTM and ISO/ASTM dosimetrystandards.
1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establishappropriate safety and health practices and to determine theapplicability or regulatory limitations prior to use.
