Abstract

The National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) for seaweed was developed through an interlaboratory comparison with 24 participants from 16 countries. After evaluating different techniques to calculate certified values for the radionuclides, the median method was found to be the most representative technique. The certified values were provided for 13 radionuclides and information values were given for 15 more radionuclides. Results for the natural decay series showed disequilibrium in both the uranium and thorium series. © 2006 Elsevier Ltd. All rights reserved.

Abstract

Prior to 2002, no comparisons of radon activity concentration had been performed within the scope of the EUROMET. The comparison presented here fulfils the need to provide confidence in the capability of national metrology institutes and calibration laboratories to measure radon activity concentration in air. This has been achieved by the measurement of radon reference atmospheres using an electronic, radon measuring instrument as the transfer comparison device (CD). Each of the twelve institutes, from nine countries, calibrated the CD using standard calibration procedures according to their quality system, at three different activity concentrations: 1 kBq/m3, 3 kBq/m 3 and 10 kBq/m3. For each activity concentration, a comparison reference value and its uncertainty have been derived. From these the degrees of equivalence have been calculated and are presented graphically and in the form of matrices. All the results are consistent within the assigned uncertainties. Main text.

The final report has been peer-reviewed and approved for publication by EUROMET, according to the provisions of the Mutual Recognition Arrangement (MRA).

Abstract

The costs of monitoring for internal exposure in the workplace are usually significantly greater than the equivalent costs for external exposure. Therefore, there is a need to ensure that resources are employed with maximum effectiveness. The EC-funded OMINEX (optimisation of monitoring for internal exposure) project is developing methods for optimising the design and implementation of internal exposure monitoring programmes. Current monitoring programmes are being critically reviewed, the major sources of uncertainty in assessed internal dose investigated, and guidance formulated on factors such as programme design, choice of method/techniques, monitoring intervals, and monitoring frequency. OMINEX will promote a common, harmonised approach to the design and implementation of internal dose monitoring programmes throughout the EU.
