They should look at the thyroids of children living in Fukushima. Something like 60% are showing signs of exposure. Doctors in Japan have been ordered not to tell parents that their children’s health problems may be related to the disaster.
This is about well managed British nukes. Not about the Japanese disaster.
I am 67 years old and worked in the nuclear propulsion and nuclear power plants for 40 years. Retired 2 years ago and no health issues. Draw your own conclusions.
