ISO/ASTM 51702:2013,Practice for dosimetry in a gamma facility for radiation processing.
ISO/ASTM 51702:2013 outlines the installation qualification program for an irradiator and the dosimetric procedures to be followed during operational qualification, performance qualification, and routine processing in facilities that process products with ionizing radiation from radionuclide gamma sources to ensure that product has been treated within a predetermined range of absorbed dose.
4. Significance and use
4. 1 Various products and materials routinely are irradiatedat predetermined doses in gamma irradiation facilities to reduce their microbial population or to modify their characteristics. Dosimetry requirements may vary depending upon their radiation application and end use of the product. Some examples of irradiation applications where dosimetry may be used are:
4.1.1 Sterilization of medical devices;
4. 1.2 Treatment of food for the purpose of parasite andpathogen control, insect disinfestation, and shelf life extension;
4.1.3 Disinfection of consumer products;
4. 1.4 Cross-linking or degradation of polymers and elastomers
4.1.5 Polymerization of monomers and grafting of monomers onto polymers;
4. 1. 6 Enhancement of color in gemstones and other materials;
ds
4. 1. 7 Modification of characteristics of semiconductor de-vices. and
4. 1. 8 Research on materials effects.
