ISO/ASTM 51261

Description / Abstract: This practice specifies the requirements for calibrating routine dosimetry systems for use in radiation processing, including establishing measurement traceability and estimating uncertainty in the measured dose using the calibrated dosim- etry system.

NOTE 1—Regulations or other directives exist in many countries that govern certain radiation processing applications such as sterilization of healthcare products and radiation processing of food requiring that absorbed-dose measurements be traceable to national or international standards (ISO 11137-1, Refs (1-3)²).

The absorbed-dose range covered is up to 1 MGy.

The radiation types covered are photons and electrons with energies from 80 keV to 25 MeV.

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 ASTM E2628 "Practice for Dosimetry in Radiation Processing" for the calibration of routine dosimetry systems. It is intended to be read in conjunc¬tion with ASTM E2628 and the relevant ASTM or ISO/ASTM standard practice for the dosimetry system being calibrated referenced in Section 2.

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 appro¬priate safety and health practices and determine the applica¬bility of regulatory limitations prior to use.
