The growing outrage over the Transportation Security Administration’s new policy of backscatter scanning of airline passengers and “enhanced pat-downs” brings to mind these wise words from President Ronald Reagan: “The nine most terrifying words in the English language are: ‘I’m from the government and I’m here to help you.’”
So, what is all the concern really about — will these radiation scanners increase your risk of cancer or other diseases? A group of scientists and professors from the University of California at San Francisco voiced their concern to Obama’s science and technology adviser John Holdren in a well-stated letter back in April.
The group included experts in radiation biology, biophysics, and imaging, who expressed “serious concerns” about the “dangerously high” dose of radiation to the skin.
Radiation increases cancer risk by damaging the DNA and various components within the cells. Much of the damage is caused by high concentrations of free radicals generated by the radiation. Most scientists think that the most damaging radiation types are those that have high penetration, such as gamma-rays, but in fact, some of the most damaging radiation barely penetrates the skin.
