Laboratories interested in the analysis of natural and man made radionuclides from the fall-out.
Participants will receive one moss-soil sample of 100 grams, and three spiked water samples of 500 grams.
For gamma emitting radionuclides the design of the proficiency test will be such that the participants will be asked to analyse the moss-soil and water samples for the following radionuclides K-40, Co-60, Zn-65, Cs-134, Cs-137, Cd-109, Ba-133, Ce-144, Eu-155, Pb-210, Ra-226, Ac-228, Th-234 and Am-241. It should be noted that only some of the listed radionuclides will be present in the samples. The levels of the radionuclides are such that they can be measured within a 12 hour measurement period using a conventional HPGe g‑spectrometer of 35% relative efficiency.
For radiochemical analysis the participants will be asked to analyse the moss-soil sample for the following radionuclides
Sr-90, Po-210, Th-232, U-234, U-238, Pu-238, Pu-239+240 and Am-241.
Below 1000 Bq kg-1 for each of the radionuclides.
and below 20 Bq kg-1 for each of the radionuclides in the spiked water.
