Fukushima Plays Shoot The Messenger On Radiation

TWENTY-FIVE years after Chernobyl, many billions of dollars are at stake if the Fukushima reactor meltdowns cause the so-called "atomic renaissance'' to halt or even slow down. This is evident from the nuclear industry's vociferous attacks on its critics.

We see this especially in Australia, where the industry is conducting a whatever-it-takes propaganda campaign to ensure that nothing stands in the way of vast profits to be made from continuing to export uranium; from the plan to establish a radioactive waste dump at Muckaty Station in the Northern Territory; and from the industry's desire to dot the continent with reactors.

Yet by reassuring the public that things aren't too bad, Monbiot and others misrepresent and distort the scientific evidence of the harmful effects of radiation exposure.

Their first piece of disinformation is to confuse the effects of external and internal radiation. The former is what populations were exposed to when atomic bombs were detonated over Hiroshima and Nagasaki in 1945.

Internal radiation, by contrast, emanates from radioactive elements that enter the body by inhalation, ingestion, or skin absorption. Hazardous radioactive elements being released in the sea and air around Fukushima accumulate at each step of various food chains (for example, into algae, crustaceans, small fish, bigger fish, then humans; or soil, grass, cow's meat and milk, then humans). Entering the body, these elements - called internal emitters - migrate to specific organs such as the thyroid, liver, bone, and brain, continuously irradiating small volumes of cells with high doses of alpha, beta and/or gamma radiation, and over many years often induce cancer.

Further, many remain radioactive in the environment for long periods, posing danger for future generations.
