Strahlenschutz-Messgeräte - Passive, integrierende Dosimetriesysteme zur Umwelt- und Personenüberwachung - Teil 1: Allgemeine Eigenschaften und Leistungsanforderungen (IEC 62387-1:2007, modifiziert); Deutsche Fassung EN 62387-1:2012
Overview
This standard applies to all kinds of passive dosimetry systems that are used for measuring - the personal dose equivalent Hp(10) (for whole body dosimetry), - the personal dose equivalent Hp(0,07) (for both whole body and extremity dosimetry), or - the ambient dose equivalent H*(10) (for environmental dosimetry). It applies to dosimetry systems that measure external photon or beta radiation in the dose range between 0,01 mSv and 10 Sv and in the energy ranges given in a table. All the energy values are mean energies with respect to the prevailing dose quantity. The dosimetry systems usually use electronic devices for the data evaluation and thus are often computer controlled. In addition, this standard can be applied for testing neutron dosimetry systems. This concerns the testing concerning the design of the dosimetry system, the instruction manual, the software, environmental influences, electromagnetic influences, mechanical influences and the documentation. The tests utilizing radiation shall be done with neutron reference radiation qualities according to ISO 8529. In some countries the presence of beta dose has to be indicated by dosimeters worn on the trunk. Such an indication of the presence of beta dose is not a measurement. For that reason, a specific subclause deals with the indication of the presence of beta dose. Full compliance with this standard is given if the requirements for the mandatory ranges given in Tables 3 to 5 are fulfilled. If the customer or manufacturer requires extended ranges then the tests shall also be performed as specified in this standard. That means, the requirements given in Tables 3 to 5 apply as well. Thus, dosimetry systems can be classified by stating a set of ranges (for example, for dose, for energy, for temperature) within which the requirements stated in this standard are met. The absolute calibration of the dosimetry system is not checked during a type test according to this standard as only system properties are of interest. The absolute calibration is checked during a routine test. 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).
