![]() ![]() To estimate the standard uncertainty associated with the property value the MM-median based Standard Deviation S(MM-median) was calculated from the span of the central 50% of the MM-PDF density function. The property values of all radionuclides were established on the basis of the Mixture Model Median (MM-median) of the analytical results reported by the expert laboratories. LNHB (France), MNA (Malaysia), IJS (Slovenia), AECS (Syria), and the IAEA Laboratories (Austria). ![]() * Uncertainty is expressed as a Mixture model median based standard deviation S(MM-median) at 95 % confidence level.įour National Metrological Institutes (NMI) and seven expert laboratories nominated by their respective NMI took part in the IAEA-434 interlaboratory comparison namely: ERISS (Australia), PTB (Germany), HAA (Hungary), ARPA (Italy), KINS (Korea), KRISS (Korea), Radiation processing for safe, shelf-stable and ready-to-eat food. Codex Guidelines on Measurement Uncertainty, CAC/GL 54-2004. ![]() Results of a Coordinated Research Project 1998-2002. Reference date for decay correction: Analyte Irradiation as a Phytosanitary Treatment of Food and Agricultural Commodities. After bottling the material was sterilized by gamma ray irradiation with a total dose of 25 kGy using a Co-60 source according to EN ISO 13485:2003 to ensure long-term stability of the material by inhibiting microbial action. Portions of 250 g each were filled into plastic bottles, sealed with security polyethylene caps and labeled with the code IAEA-434. Bottling of IAEA-434 was carried out under normal laboratory conditions. The material was dried and milled by air jet mill to less than 100 μm, and homogenized. The material was obtained from a processing plant located in Gdansk (Poland) in 2003. ![]()
