Cesium-137 deposition and contamination of Japanese soils due to the Fukushima nuclear accident
Pieter Franken

As I understand from a review of this work by whom I believe is a
KEK researcher, this is a simulation result based on data from
20th March to 19th April, suggesting lack of influence of the
large fall out on 15th March.
Still, this work shows an interesting suggestion that east of
Hokkaido may have high level of contamination, which should be
verified by actual measurements.

explained. Unfortunately the output from their modeling
does not align with field measurements, pointing out
severe weaknesses in either the model (FLEXPART) or its
limitations given imperfect input data. Or cesium
depositions on dates outside the range used were more
intense than assumed and dominate the actual total
contamination values observed.
On second thought, no, that could only account for
underestimates. The maps in this paper also show areas
where more cesium is predicted than is present. So
this paper only shows that their model needs further
development or better source data.
