EC Proficiency Testing on I-131, Cs-134, and Cs-137 in maize powder

Description

This proficiency testing (PT) exercise focuses on the analysis of I-131, Cs-134, and Cs-137 in maize powder. This PT is organised to ensure the quality of the results reported to the European monitoring networks under Art. 35 and 36 of the EURATOM Treaty and to improve the knowledge on the measurement methods used by the laboratories in the Member States. The main objective of this exercise is to assess the capabilities of nominated laboratories.

Registration is free of charge.

Test materials and analytes

The test material to be analysed consists of maize powder spiked with standardised radioactive solutions and placed in an amber glass bottle. Each participant will receive one bottle of the test item, with around 100 g of powder.

General outline of the exercise

Participants are requested to perform 1 - 3 independent analyses using the method of their choice, and to report their result for the PT assessment, its associated measurement uncertainty and coverage factor k.

Detailed instructions will be sent together with the test sample.
