ASTM-51939 › Standard Practice for Blood Irradiation Dosimetry
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This practice outlines irradiator installation qualification and dosimetric procedures to be followed in the irradiation of blood and blood products by the blood-banking community. If followed, these procedures will help to ensure that the products processed with ionizing radiation from gamma, bremsstrahlung X-rays or electron sources receive absorbed doses within a predetermined range.
1.2 This practice covers dosimetry for the irradiation of blood for these types of irradiators: self-contained dry-storage 137Cs or 60Co irradiators (free-standing irradiators), teletherapy units, self-contained bremsstrahlung X-ray units and electron accelerators. The absorbed dose range for blood irradiation is typically 15 Gy to 50 Gy.
1.3 This practice also covers the use of radiation-sensitive indicators for the visual and qualitative indication that the product has been irradiated.
1.4 This practice is intended for use by technically and non-technically oriented people. It, therefore, contains more tutorial information than many other ASTM and ISO/ASTM dosimetry standards.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability or regulatory limitations prior to use.
