IAEA-TEL-2012-03 World Wide Open Proficiency Test
Status: Final evaluation reports in preparation
World-wide proficiency test, IAEA-TEL-2012-03, on the determination of anthropogenic gamma-emitters in water in the presence of natural background, of radio-caesium in hay and of both natural and anthropogenic radionuclides in soil samples
The IAEA Terrestrial Environmental Laboratory is planning to organise a proficiency test on the determination of the anthropogenic and natural radionuclides in water, hay and soil samples according to the following schedule:
- Target group: World-wide laboratories who are interested in the determination of the anthropogenic and natural radionuclides in environmental samples
- Tap water, spiked with anthropogenic radionuclides and with 226Ra to simulate a natural background.
- Hay, collected in Austria shortly after the Chernobyl accident "naturally contaminated" with 137Cs and spiked with 134Cs isotope.
- Soil, from "Jeju Island" (Korea, Republic of), containing anthropogenic and natural radionuclides. The sample is milled, sieved under the 150 micron particle size and sterilized with 20 kGy gamma dose.
- Sample Set: Each participant will receive three water samples, 500 g each, one hay sample (150 g) and one soil sample (200 g).
- Target analytes (tentative):
in water: unknown gamma-emitters,
in hay: 134Cs and 137Cs,
in soil: 90Sr, 137Cs, TRU and natural radioisotopes.
These analytes will be evaluated against pre-established reference values and associated uncertainties.
- Target dates (tentative):
- 22 Oct. 2012 - Opening date for on-line registration
- 16 Nov. 2012 - Closing date for on-line registration
- 1st Dec. 2012 - Organizer confirmation of the participation in the PT
- 14 Jan 2013 - Shipment of the samples
- !13 May 2013 - Results submission deadline!
- 03 June 2013 - Individual evaluation reports
30 April - 10 May 2014 - Final evaluation reports distribution
- 30 May 2014 - Draft of summary report
- 31 December 2014 - Final of summary report
