I recently had an article published in the UK's Daily Telegraph about the health situation in Fukushima. It was based upon two visits I made to the evacuation zone, the first in December 2018 with photographer Simon Townsley, whose evocative photos accompany the story here (free registration required to view full article).
In addition to venturing deep into the evacuated zone, Simon and I also jumped aboard a fishing boat to take an early morning trip out into the Pacific with a group that takes samples of water samples near the two Fukushima nuclear plants for analysis.
It was a fascinating trip and opinions still differ hugely on the health risks. On the one hand there have been few deaths directly resulting from radiation exposure (based on information actually reported to date) and confirmed or suspected thyroid cancers among children are thought by some experts to be unrelated to the Fukushima nuclear accident. At the same time, the views of those same experts are refuted by the likes of Greenpeace and Japanese government's attempts to paint a rosy picture of the situation (not to mention historical collusion with the energy sector) does give one pause.
From my experience during these most recent visits to the zone, I would err on the side of caution: armed with a Geiger counter, I took regular radiation measurements and one area where we visited was more than 350 times the safe limit stipulated by the International Atomic Energy Agency!
