Inter-laboratory exercise with an aim to compare methods for Sr-90 and Pu-239,Pu-240 determination in environmental soil samples
Journal article, 2017
In order to deliver reliable results for a multitude of different scenarios, e.g. emergency preparedness, environmental monitoring, nuclear decommissioning and waste management, there is a constant process of method development in the field of radioanalytical chemistry. This work presents the results of a method comparison exercise aimed at quantifying Sr-90 and Pu-239,Pu-240 in environmental soil samples, with the intention of evaluating the performance and applicability of different methods. From the methods examined in this work, recommendations are given in order to find a radioanalytical measurement procedure, for Sr-90 and Pu-239,Pu-240 analysis, which is fit-for-purpose for a particular scenario.
