Project Overview

The overall objective of this project is to improve SI traceable measurements of operational radiation protection quantities in the participating NMIs from emerging countries.

This project will ensure that they have adequate equipment and procedures for measuring and assessing human exposure and radioactive contamination of the environment. The main goal of this project is to establish and harmonise the procedures for the calibration of radiation protection dosimeters in various types of radiation protection beams with a special focus on achieving a measurement uncertainty of 5 % (k=2) or less.

The improvement will be accomplished through research on operational quantities for external radiation exposure and secondary standards for eye lens dosimetry. In addition to these main goals, participating NMIs will prepare individual strategies for radiation protection metrology development and they will discuss them with the EURAMET community in order to ensure a coordinated and optimised approach.

Objectives

The specific objectives of the project are:

1. To develop traceable measurement capabilities for operational radiation protection quantities, including the full characterisation of a measurement setup conversion procedure from air kerma (kinetic energy released per unit mass) to (Hp(0.07), Hp(3), Hp (10), H’(0.07), H’(3), H*(10) operational quantities with an uncertainty of 5 % (k=2) or less. The applicable photon energy range and dose rate range are 5 keV   7000 keV and 0.05 μSv/h to 100 Sv/h respectively.
2. To validate the developed measurement capabilities for operational radiation protection quantities, to ensure that within an applicable energy range, from 5 keV to 7 MeV and dose rates, 0.05 µSv/h to 100 Sv/h, the accuracy of the dose measurement under well-defined calibration conditions has to be at least 5 % (k=2), by organising and undertaking a intercomparison in dosimetry, including activities related to travelling standards, technical protocols, logistical provisions, and the evaluation of intercomparison results.
3. To develop and submit draft CMCs for the traceable calibration of dosimeters, thus proving the international equivalence of their measurement standards and the calibration and certificates that they issue.
4. For each partner, to develop an individual strategy for the long term operation of the capacity developed, including possible regulatory support, research collaborations, quality control, the quality management system and accreditation. They should also develop a strategy for offering calibration services from the established facilities to their own country and neighbouring countries. The individual strategies should be discussed within the consortium and with other EURAMET NMIs/DIs, to ensure that a coordinated and optimised approach to the development of traceability in this field is developed for Europe as a whole.
