Abstract

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 90Sr and 239,240Pu 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 90Sr and 239,240Pu analysis, which is fit-for-purpose for a particular scenario.

    In the original article, the LOD assigned to method Sr-B in Table 1 was published incorrectly as 24 Bq/kg, the correct LOD for that method should be 10.4 Bq/kg. As a consequence the range of LODs, as presented in the first sentence of the section Limit of detection should be stated as “It can be seen from Table 1 that, the LODs of 90Sr vary from 0.2 to 10.4 Bq/kg among the four methods used in this work”.
