DIN IEC/TS 62743:2013-04

The specification and determination of the special characteristics required for dosemeters to be used in pulsed fields of ionizing radiation have been excluded from all standards for direct reading personal and environmental dosemeters issued before 2012 for radiation protection purposes. This Technical Specification provides the necessary information for the measurement of one single radiation pulse, which is the most difficult situation to be measured. The characteristics of a dosemeter for repeated pulses are expected to be better than for one single radiation pulse with the same parameters but worse than for continuous radiation. This specification applies for such direct reading dosemeters that use pulse counting for the determination of the measured dose value. Dosemeters that use delayed pulses, for example, due to activation by neutrons, are excluded. As a help to the user to judge whether or not the dosemeter under consideration can be used, Table A.1 in the informative Annex A gives some parameter values for typical workplaces where pulsed radiation occurs. They are based on the knowledge available in 2012 and may change with the next generation of pulsed radiation generating equipment. This Technical Specification contains much information for which worldwide experience is not available at the date of its development. Therefore, the responsible IEC working committee decided to publish the publication prepared on the basis of knowledge yielded by the German project management as a Technical Specification for the time being. The responsible committee is GUK 967.3 "Strahlenschutzdosimeter" ("Radiation protection devices") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE, Joint Committee with the Radiology Standards Committee (NAR).
