Evaluaton of dose rate data provided by non-governmental networks

Abstract

In recent years, the number of non-governmental networks providing quasi real time dose rates is growing. This data is available to the general public via open access based platforms on the internet. The research on the non-governmental networks is scarce and the measurements represented there are mostly carried out using broadly available commercial simple hand-held devices. Without proper testing of these devices in metrological laboratories, there is a significant possibility for discrepancies between the official and non-governmental data, which may have wider implications. Within project 16ENV04 Preparedness, a systematic study of non-governmental networks produced a list of 16 types of dosimeters that are commonly used. Four dosimeters of each type were sourced and commissioned by project partners and are currently undergoing the testing. Test procedures are shortly described in this paper and preliminary results for 2 types of dosimeters are presented.
