This unique publication contains 31 of the latest standards on dosimetry for the radiation processing industry. These standards were developed by ASTM International's Subcommittee E10.01 on Dosimetry for Radiation Processing, which is comprised of most individuals, worldwide, known to be active in this field.
To complement the ASTM dosimetry effort, a working group (WG3 ) was formed in 1996 under the International Organization for Standardization (ISO) Technical Committee TC85, and, after a period of 4 years, twenty of the completed ASTM standards were adopted by ISO. To prevent divergence of the ASTM and ISO versions of the standards at some future time, and to avoid duplication of effort, a Pilot Project was then created between ISO and ASTM to allow ASTM to remain in charge of the maintenance of the resulting published ISO/ASTM standards, with unrestricted participation from the ISO experts.
Twenty-five dosimetry standards have now been published as ISO/ASTM standards, and are included in this publication. Two of the standards are specifically for food irradiation applications, but the majority apply to all forms of gamma, X-ray, and electron-beam radiation processing, including dosimetry for the sterilization of health care products, for the radiation processing of fruits, vegetables, meats, spices, processed foods, plastics, inks, medical wastes and paper, and for the sterilization of insects.
Most of the standards specify exact procedures for using individual dosimetry systems or for characterizing various types of irradiation facilities. Others cover the selection and calibration of dosimetry systems, dose mapping, mathematical methods for calculating dose, and the treatment of uncertainties using the ISO-recommended Type A and Type B method for estimating measurement uncertainty. Additional standards are now being developed by ASTM Subcommittee E10.01.
This publication also includes five published ASTM dosimetry standards which have not yet been proposed as ISO/ASTM standards. Seventeen of the standards are either revisions of versions in the first edition of this publication or are completely new standards. This volume also contains ASTM Terminology Standard E170, which provides definitions of terms that apply to radiation measurements and dosimetry, and a Glossary consisting of an alphabetical listing of all the definitions found in the individual dosimetry standards.
This volume is a valuable resource for operators of commercial radiation processing plants, operators and researchers at university and government research facilities, government regulators and inspectors, and dosimetry experts worldwide. |
