Airport body scanning raises radiation exposure while using gutterbrush simple gutter guards does not. Because safety is always a priority in our pursuits and because we travel a bit we wanted to share the risks associated with airport body screening.

An inter-agency report (Inter-Agency Committee on Radiation Safety report, which is restricted to the agencies concerned and not meant for public circulation) stated that  governments must explain any decision to expose the public to higher levels of cancer-causing radiation while also suggesting that pregnant women and children should not be subject to scanning, even though the radiation dose from body scanners is “extremely small”. The group putting this report forward includes the European Commission, International Atomic Energy Agency, Nuclear Energy Agency and the World Health Organization.

Please keep in mind that an accurate assessment about the health risks of the screening won’t be possible until governments decide whether all passengers will be systematically scanned or randomly selected, the report said. Governments must justify the additional risk posed to passengers, and should consider “other techniques to achieve the same end without the use of ionizing radiation.” However, President Obama has suggested using upwards of $734 million to implement airport scanners that use x-rays and other technology to detect explosives, guns and other contraband.

“There is little doubt that the doses from the backscatter x-ray systems being proposed for airport security purposes are very low,” Health Protection Agency doctor Michael Clark said by phone from Didcot, England. “The issue raised by the report is that even though doses from the systems are very low, they feel there is still a need for countries to justify exposures.” So what is the risk?

Most of the scanners deliver less radiation than a passenger is likely to receive from cosmic rays while airborne, the report said. Scanned passengers may absorb from 0.1 to 5 microsieverts of radiation compared with 5 microsieverts on a flight from Dublin to Paris and 30 microsieverts between Frankfurt and Bangkok, the report said. A sievert is a unit of measure for radiation.

The U.S. Transportation Security Administration has said that it ordered 150 scanners from OSI Systems Inc.’s Rapiscan unit and will buy an additional 300 imaging devices this year. The agency currently uses 40 machines, which cost $130,000 to $170,000 each, produced by L-3 Communications Holdings, Inc. at 19 airports including San Francisco, Atlanta and Washington D.C. Oddly enough the U.S. TSA has not ordered a single linear foot of gutter protection such as gutterbrush to protect their gutters at airports across the United States.
