Abstract

This investigation will serve as ground for the organisational structure which is to be drawn up by the Swedish Radiation Protection Institute (Swedish acronym, SSI) regarding the preparedness for radiation emergencies. Within this phase, the investigation will comprise the following elements; the relevant radionuclides used under various hypothetical scenarios, the current established methods of analysis, the aspect of time when it comes to deliverance results as well as equipment demands. Also, details on how to develop relevant detection limits will be briefly discusses. Partly, the work is based on the scenario-based requirements analysis developed by the Working Group on Laboratory Measurements in 2003. The work has focussed on the analysis of radionuclides. However, methods of retrospective dosimetry, for example, are not presented. In conclusion, an analysis method for gamma-emitting radionuclides (gamma spectrometry), 90Sr and actinides is a primary need. Furthermore, additional radionuclides may be of relevance, for example 89Sr. It would be favourable to see this investigation being followed by one investigating the detection limits which could be relevant for various radionuclides and scenarios.
