A proposed countermeasure simulation model for the new ICRP recommendations

Abstract

(icRp, 2007) takes into account all terrestrial exposure pathways, including ingestion, and considers sheltering, evacuation, relocation, food restrictions, and the use of iodine tablets for thyroid blocking, for reducing or avoiding doses. The screening goal is the identification of action strategies that limit the total effective equivalent dose received from all pathways over a given time period, the "criterion dose", below a given reference level.the proposed model represents a consistent and holistic approach to solve such a problem, by treating in one screening assessment sheltering, evacuation and relocation together, and linking the outcome via the criterion dose and the reference level to the ingestion pathways. Due to its specific characteristics, thyroid blocking does not fit well into the procedure.

An application example for the new ICRP screening tool of JRodos

“…The inhalation dose contribution to the criterion dose is recalculated under the assumption of 100% efficiency; see (Landman et al, 2013). If that suffices to reduce the modified criterion dose below the reference level, the problem is considered to be solved and the cells are characterised by an "iodine tablets sufficient" tag.…”

“…As part of the work performed in the framework of the project "Towards a self-sustained European Technology Platform (NERIS-TP) on Preparedness for Nuclear and Radiological Emergency Response and Recovery", a screening tool was developed (Landman et al, 2013) that accounts for the new ICRP-103 recommendations (ICRP, 2007); it was implemented in the program environment of the decision support system JRodos (Ievdin et al, 2010) under the model name "ICRP" as version ICRP 1.0.…”

European model for inhabited areas – ERMIN 2

“…A new screening module has been developed for RODOS that considers all pathways of exposure (Landman et al, 2013). Inevitably, there will be situations in which emergency actions fail to reduce the residual dose below the reference level.…”
