Helen Caldicott, the Australia-born American physician and anti-nuclear activist of the late 1970s and early 1980s, was a practitioner of paediatrics at the Children’s Hospital Medical Center in Boston, U.S. A leading critic of nuclear technology and armament industries, she tried to conscientise the world through her almost solitary protest writings and TV and radio appearances against the dangers of nuclear technology for the environment.
In the light of Fukushima (2011), Chernobyl (1986) and Three Mile Island (1979) nuclear accidents (all of which happened after 1978) and the great concern they generated in the world during the last four decades, Caldicott’s 1978 book Nuclear Madness assumes prophetic significance.

On day one of NOW DC ( http://nowdc.org ) Helen Caldicot speaks at the EPA about nuclear radiation and the need to shut down the dozens of reactors in the United States that are identical to the Fukishima plant and they are also on mostly on fault lines.
Governments Worldwide Raise Acceptable Radiation Levels Based Upon Politics … Not Science
*Note: Single radiation dose of 2,000 millisieverts (200,000 millirems) and above causes serious illness. See also exposure list below.
Half-life of some radioactive elements
In addition, Fukushima’s Unit 3 reactor also used MOX [mixed oxide], a plutonium-uranium fuel mixture that is deadly. A single milligram of MOX is 2-million times more deadly than enriched uranium.
[NOTE: Half-life is the time taken for a radioactive substance to decay by half.]
* Cesium-134 ~ 2 years
* Cesium-137 ~ 30 years
* Iodine-131 ~ 8 days
* Plutonium-239 ~ 24,200 years
* Ruthenium-103 ~ 39 days [Ruthenium is a fission product of uranium-235.]
* Ruthenium-106 ~ 374 days
* Strontium-90 ~ 28.85 years [Strontium-90 is a product of nuclear fission and is found in large amounts in spent nuclear fuel and in radioactive waste from nuclear reactors.]
* Uranium-234 ~ 246,000 years
* Uranium-235 ~ 703.8 million years
* Uranium-238 ~ 4.468 billion years
