ProPublica has released a new report detailing the medical risks of radiation based scanners in use by the TSA at the nation’s airports.

On Sept. 23, 1998, a panel of radiation safety experts gathered at a Hilton hotel in Maryland to evaluate a new device that could detect hidden weapons and contraband. The machine, known as the Secure 1000, beamed X-rays at people to see underneath their clothing.

“I think this is really a slippery slope,” said Jill Lipoti, who was the director of New Jersey’s radiation protection program. The device was already deployed in prisons; what was next, she and others asked — courthouses, schools, airports? “I am concerned … with expanding this type of product for the traveling public,” said another panelist, Stanley Savic, the vice president for safety at a large electronics company. “I think that would take this thing to an entirely different level of public health risk.”

The machine’s inventor, Steven W. Smith, assured the panelists that it was highly unlikely that the device would see widespread use in the near future. At the time, only 20 machines were in operation in the entire country.

“The places I think you are not going to see these in the next five years is lower-security facilities, particularly power plants, embassies, courthouses, airports and governments,” Smith said. “I would be extremely surprised in the next five to 10 years if the Secure 1000 is sold to any of these.”

Today, the United States has begun marching millions of airline passengers through the X-ray body scanners, parting ways with countries in Europe and elsewhere that have concluded that such widespread use of even low-level radiation poses an unacceptable health risk. The government is rolling out the X-ray scanners despite having a safer alternative that the Transportation Security Administration says is also highly effective.

Note who made this decision that involves medical risks. Not the FDA which has responsibility for regulating X-ray devices, but the TSA? What medical studies were done? How reliable is the testing the day-to-day operation of these devices? Who is checking to protect the TSA employees from health threats that might come from working around such machines day after day?  A TSA administrator claims that “It’s a really, really small amount relative to the security benefit you’re going to get.” What is that conclusion based on? Where is the data, the analysis and the conclusion, in writing?
