ISO/ASTM 52628:2013,Standard practice for dosimetry in radiation processing.ISO/ASTM 52628:2013 pdf free download.
ISO/ASTM 52628:2013 describes the basic requirements that apply when making absorbed dose measurements in accordance with the ASTM E61 series of dosimetry standards. In addition, it provides guidance on the selection of dosimetry systems and directs the user to other standards that provide specific information on individual dosimetry systems, calibration methods, uncertainty estimation and radiation processing applications.
ISO/ASTM 52628:2013 applies to dosimetry for radiation processing applications using electrons or photons (gamma- or X-radiation).
ISO/ASTM 52628:2013 addresses the minimum requirements of a measurement management system, but does not include general quality system requirements.
The use of ionizing radiation for the treatment of commercial products such as the sterilization of medical devices, the reduction of microbial contamination in food or the modification of polymers is referred to as radiation processing. The types of radiation used may be gamma radiation (typically from cobalt-60 sources),X-radiation or accelerated electrons
The development, validation and routine control of a radiation process comprises a number of activities, most of which rely on the ability to measure the delivered dose accurately. It is therefore necessary that dose is measured with traceability to national, or international, standards, and the uncertainty is known, including the effect of influence quantities. The E61 standards on radiation processing dosimetry serve to fulfill these requirements.
The practices describing dosimetry systems have several common attributes, and there is a need to have one general standard that can act as a common reference and that can be used as a basis for the selection of dosimetry systems for defined taskS. ISO/ASTM Practice 52628 serves this purpose. It outlines general requirements for the calibration and use of dosimetry systems and for the estimation of measurement uncertainties. Details relating to each dosimetry system are found in the respective standards and each of these refer to ISO/ASTM Practice 52628 for the general requirements.
