IRSN Fukushima Report

The French Institut de radioprotection et de sûreté nucléaire (IRSN) (“Radioprotection and Nuclear Safety Institute”) published a new report “ASSESSMENT ON THE 66TH DAY OF PROJECTED EXTERNAL DOSES FOR POPULATIONS LIVING IN THE NORTH-WEST FALLOUT ZONE OF THE FUKUSHIMA NUCLEAR ACCIDENT – OUTCOME OF POPULATION EVACUATION MEASURES -“.

Regarding this report, Dr. Arjun Makihijani, President of the Institute for Energy and Environmental Research, made the following comment:

This is indeed a terrible prognosis for doses. The people of the area simply cannot be allowed to have accumulated doses of these magnitudes. A policy for cleanup of the contaminated areas and for protecting children especially is very necessary. The evacuation policy, while understandable for the first few weeks, is revealed to be quite messy as the accident continued. One reason is that it was eminently clear by then that the pattern of contamination would not follow a radially declining mode and that hot spots and preferential directions had already developed.

Estimation of internal doses (ingestion, inhalation) is important. As the IRSN notes, internal doses were not included in its analysis. Moreover, doses from the radioactive isotopes of iodine were also not included.

And the accident is not over yet. This means that cesium-134 and cesium-137 contamination could increase, even as cesium-134 already deposited (half-life 2.1 years) decays.

The German and Swiss response is the only sensible one for Japan. Specifically, if Japan made a similar decision, they could better focus on clean up and public protection without having one eye on how they might continue keeping the nuclear plants in operation. This would also allow the spent fuel that has aged somewhat to be located in more secure dry facilities and away from tsunami threats.
