“…This field consists of both cosmic radiation and terrestrial (gamma) radiation from the soil. As an interim solution, the IEC has published some guidance points on the calibration of dosemeters in the standard for ambient dose equivalent meters, IEC 60846 [23], in the informative Annex C. Additional guidance can be found in the Technical Recommendations of the EURADOS Working Group 12 (see [24] and therein [1]).…”

Measurements for radiation protection dosimetry in medicine, industry, science and in the environment require instruments for photon, beta and neutron radiation and for combinations of them. To characterize and calibrate such instruments reference radiation fields are required, together with the dosimetry of these fields and the methods to calibrate the instruments. For all these tasks standards are available; an overview of them is given in this paper. In addition, an overview of secondary standard instruments is provided which serve as a tool to ensure the traceability between the primary standards laboratories and the calibrating and type testing laboratories. The part on neutrons is kept short as neutrons will be dealt with in a future special issue in this journal.About 10 years ago, Böhm et al (1999 Radiat. Prot. Dosim. 86 87–105) summarized the ISO recommended reference radiations used in radiation protection. This paper updates that review and adds environmental radiation and secondary standard instruments.

“…In particular, to assess the energy and angle response characteristics of the performance of dosemeters in fields simulating those found in the workplace, similar to routine monitoring conditions. The simulated workplace fields can be devised to reproduce features of fields encountered in practice by selection of components from the ISO recommended fields (13)(14)(15)(16) and combined sequentially. Alternatively, specific workplace fields can be simulated, particularly for neutrons, and then be fully characterised by both calculation and measurement (12,17,18) .…”

Radiation Protection Dosimetry

The current situation amongst Member States is that there are widely differing national requirements for dosimetric services and for dosemeter performance. It is clear that with the free movement of workers within the European Union (EU) and the requirements for individual dosimetry given in Council Directive 96/29 EURATOM, a degree of harmonisation of requirements and procedures of EU Member States would be desirable. A EURADOS action group, made up of members from each of the EU Member States plus Switzerland, was set up with the overall objectives of consolidating within the EU the quality of individual monitoring using personal dosemeters and assisting movement towards harmonised procedures. An outline of the work of the action group is given and the term 'harmonisation' is discussed.

“…Primary dosimetry for beta radiation protection has a long history at the Physikalisch-Technische Bundesanstalt (PTB) which is closely connected to the scientific work of Böhm [1][2][3][4][5][6][7][8][9][10][11][12], which found one of its highlights in the development of an extrapolation chamber for primary beta dosimetry: the Böhm chamber [13]. This has been and still is commercially available since the late 1980s [14] and is in use as the primary standard for beta dosimetry at PTB as well as many other national metrology institutes.…”

Firstly, in this work, the main characteristics of PTB’s new beta primary standard (BPS2) are presented in comparison to its previous one (BPS1), i.e., to the Böhm chamber. Secondly, the main changes of the revised ISO standard series on beta reference radiation fields, ISO 6980, are described. Finally, the application of the revised ISO 6980 to both PTB’s new and old beta primary standard is implemented. It turned out that both devices, BPS2 and BPS1, agree with each other within theier one sigma statistical uncertainties, i.e., approximately 3 % for 147Pm and 1.5 % to 1.8 % for 85Kr, 90Sr/90Y and 106Ru/106Rh radiation qualities. Therefore, as of approximately mid 2023, PTB will change from the 2004 to 2006 version of ISO 6980 to the revised version from 2022 and from the old beta primary standard, BPS1 (i.e., the Böhm chamber) to the new one, BPS2.
