DESCRIPTION

20/30408289 DC


This standard 20/30408289 DC BS ISO 21909-1. Passive neutron dosimetry systems is classified in these ICS categories:
  • 13.280 Radiation protection

This document provides performance and test requirements for determining the acceptability of neutron dosimetry systems to be used for the measurement of personal dose equivalent, Hp(10), for neutrons ranging in energy from thermal to 20 MeV 1

1

This maximal limit of the energy range is only an order of magnitude. The reference radiation fields used for the performance tests are those defined in ISO 8529-1. This means that the maximal energies could only be 14,8 MeV or 19 MeV. This document gives performance requirements to 14,8 MeV which is the typical neutron energy encountered for fusion. For fission spectra, the highest energies are around 20 MeV but the contribution to dose equivalent coming from neutrons with energy higher than 14,8 MeV is negligible.

. No distinction between the different techniques available in the market place is made in the description of the tests. Only generic distinctions, for instance, as disposable or reusable dosemeters, are considered.

This document gives information for extremity dosimetry in the Annex A, based on recommendations given by ICRU Report 66. This document addresses only neutron personal monitoring and not neutron criticality accident conditions.
