Producing Laboratory: TERC
Milk Powder

​​​​​​
The raw material used for production of IAEA-479 was high quality milk powder (26% fat content) without detectable radio-caesium and radio-strontium isotopes. The raw material was spiked with radionuclides, using dilutions of high precision radioactive certified reference solutions from metrological institutes. After spiking, it was homogenised and tested for heterogeneity. The particle size distribution of the material is between 50 and 280 µm (at 10 % and 90 % cumulative percentage, respectively).​

Reference date for all specified radionuclide decay corrections: 01 January 2020​
