ISO/ASTM DIS 51939
Practice for Blood Irradiation Dosimetry
|Publication Date:||6 June 2016|
|ICS Code (Radiation measurements):||17.240|
This practice outlines irradiator installation qualification program and the dosimetric procedures to be followed during operational qualification, performance qualification, and routine radiation processing of blood product (blood and blood components). If followed, these procedures will help ensure that blood products processed with radiation such as gamma radiation or X-radiation (bremsstrahlung) receive absorbed doses within a predetermined range.
This practice covers dosimetry for the irradiation of blood product for self-contained irradiators (free-standing irradiators) utilizing radionuclides such as 137Cs and 60Co, or X-radiation (bremsstrahlung). The absorbed dose range for blood irradiation is typically 15 Gy to 50 Gy.
The photon energy range of X-radiation used for blood irradiation is typically from 40 keV to 300 keV.
This practice also covers the use of radiation-sensitive indicators for the visual and qualitative indication that the product has been irradiated (see ISO/ASTM Guide 51539).
This document is one of a set of standards that provides recommendations for properly implementing dosimetry in radiation processing and describes a means of achieving compliance with the requirements of ISO/ASTM Practice 52628 for dosimetry performed for blood irradiation.
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
