Ionizing Radiation: Not To Worry?

Beginning with Madam Curie, the story of nuclear power and “ionizing radiation” is one where key players have consistently miscalculated or misrepresented the risks of radiation.

The victims from “ionizing radiation” include many of those who worked on the original Manhattan Project, the 200,000 soldiers who were assigned to eye witness our nuclear tests, the residents of the Western US who absorbed the lion’s share of fallout from our nuclear testing in Nevada, the thousands of forgotten victims of Three Mile Island or the likely hundreds of thousands of casualties of Chernobyl and now the Japanese reactors which hold about 1,000 times more “ionizing radiation” than the bombs dropped over Hiroshima.(1)

Every day, the jet stream carries pollution from Asian smoke stacks and dust from the Gobi Desert to the West Coast of California, contributing 10 to 60 percent of the total pollution inhaled by Californians, depending on the time of year.

Mercury is probably the second most toxic substance known after plutonium. Half the mercury in the atmosphere over the entire US originates in China. It, too, is 5,000 miles away. A week after a nuclear weapons test in China, radioactive iodine 131 could be detected in the thyroid glands of deer in Colorado, although it could not be detected in the air or in nearby vegetation.(2)

Even properly functioning nuclear plants emit a steady stream of radiation into nearby water and atmosphere, which can be inhaled directly or ingested from soil contact, plants or cows milk. Many studies confirm higher rates of cancers like childhood leukemia, and breast and thyroid cancer among people who live in the same counties as nuclear plants, and among nuclear workers.(3)

The idea that a threshold exists or there is a safe level of radiation for human exposure began unraveling in the 1950s when research showed one pelvic x-ray in a pregnant woman could double the rate of childhood leukemia in an exposed baby.(3) Furthermore, the risk was ten times higher if it occurred in the first three months of pregnancy than near the end. This became the stepping-stone to the understanding that the timing of exposure was even more critical than the dose. The earlier in embryonic development it occurred, the greater the risk.

A new medical concept has emerged, increasingly supported by the latest research, called “fetal origins of disease,” that centers on the evidence that a multitude of chronic diseases, including cancer, often have their origins in the first few weeks after conception by environmental insults disturbing normal embryonic development. It is now established medical advice that pregnant women should avoid any exposure to x-rays, medicines or chemicals when not absolutely necessary, no matter how small the dose, especially in the first three months.

Many epidemiologic studies show that extremely low doses of radiation increase the incidence of childhood cancers, low birth-weight babies, premature births, infant mortality, birth defects and even diminished intelligence.(4) Just two abdominal x-rays delivered to a male can slightly increase the chance of his future children developing leukemia.(5) By damaging genetic matter anywhere in a living cell, radiation can accelerate the aging process and diminish the function of any organ. Cells can repair themselves, but the rapidly growing cells in a fetus may divide before repair can occur, negating the body’s defense mechanism and replicating the damage.

Comforting statements about the safety of low radiation are not even accurate for adults.(6)Small increases in risk per individual have immense consequences in the aggregate. When low risk is accepted for billions of people, there will still be millions of victims. New research on risks of x-rays illustrate the point.

Radiation from CT coronary scans is considered low, but, statistically, it causes cancer in one of every 270 40-year-old women who receive the scan. Twenty year olds will have double that rate. Annually, 29,000 cancers are caused by the 70 million CT scans done in the US.(7)(8) Common, low-dose dental x-rays more than double the rate of thyroid cancer. Those exposed to repeated dental x-rays have an even higher risk of thyroid cancer.(9)

This could be the latest chapter in that long and tragic story when, once again, we were told by the powers to be “not to worry.”

Special Note:

Development of nuclear power was halted at the stage of Westinghouse-style fission reactors. We have not really progressed technologically, which means we have regressed. It is because of the blockade against science. “Nuclear power” is not a type of reactor at a given time, but a continuous dynamic of development. The lesson to be drawn is that we all should have developed fourth-generation reactors, and moved into controlled thermonuclear fusion more quickly. Fourth-generation reactors, and HTRs, are inherently safe, which means that when the reaction stops, heat production also stops, in contrast to the boiling water reactors like those in the Japanese power plants. Fusion, in particular laser fusion, would then come into play in some 40 years and supply very cheap energy. Of course, opting for this direction and pursuing our human adventure requires considerable long-term investments. They are impossible under the current financial system, which destroys the economy and is socially unjust, and that’s why we have to change systems before it is too late.

  1. Excellent article which I would like to republish on my blog and also in my book Radiation Toxicity Syndrome. I also will be recommending your four mineral bicarbonate formula which I tried to get my friends to make but they did not appreciate the importance of this formula. Please contact me at
