A new reference material for the activity concentration of (137)Cs, (40)K and (90)Sr in a dried berry matrix was certified from a batch of bilberries collected in the vicinity of the Chernobyl nuclear power plant. Radionuclides in this material were

The goal of the CCRI(II) “Realisation of the becquerel” project is to design a reproducible radioactivity standard which will increase the robustness of the current international reference system for radioactivity measurements. Tests performed wi

The most common gross alpha/beta standard methods used for drinking water analysis are discussed, and sources of interferences are reviewed from a metrological point of view. Our study reveals serious drawbacks of gross methods on the basis of an int

Radioactivity found in wild food products has assumed greater importance when assessing the total exposure of the population. For this reason, IRMM has been developing a reference material for the activity concentration of three radionuclides in bilb

A comparison was organised by the Institute for Reference Materials and Measurements (IRMM) among 73 environmental radioactivity monitoring laboratories for the determination of 15 radionuclides in soil. The reference material IAEA-375 soil was repro

In 2007/2008 the Institute for Reference Materials and Measurements (IRMM) organised an interlaboratory comparison (ILC) on the determination of 226Ra, 228Ra, 234U and 238U activity concentrations in mineral water. This paper describes the determinat

The threat to global security from terrorist attack does not solely arise from illicit use of firearms, explosives or weapons of mass destruction. Terrorist threats will inevitably become more subtle as information and expertise is acquired by terror

In 2009, the CCRI approved a supplementary comparison to be organised by the IRMM as pilot laboratory for the activity concentrations of 137Cs, 90Sr and 40K in a matrix material of dried bilberries. The organisation of this comparison and the materia

A method has been developed for measurement of the homogeneity of analyte distribution in powdered materials by use of electrothermal vaporization with inductively coupled plasma mass spectrometric (ETV-ICP-MS) detection. The method enabled the simul
