Airport scanner radiation risk low, agencies say

VIENNA (Reuters) – New full-body airport security scanners using X-rays generate much lower doses than normal background radiation, a draft report compiled by international agencies says.

Such devices, which cost about 10 times as much as conventional airport scanners, are likely to go into much wider use since a Nigerian man with explosives hidden undetected in his underwear boarded a U.S. airplane heading to Detroit on December 25.

While normal annual background radiation per person runs to about 3,000 microsieverts — a unit used to measure radiation exposure — the body scan delivers 0.1 to 5 microsevierts, the report, compiled by a group of international bodies including the European Commission and the U.N. nuclear agency said.

“This (risk) is very small,” Renate Czarwinski, head of radiation safety and monitoring at the International Atomic Energy Agency (IAEA) in Vienna, told Reuters Friday.

“Every application of X-ray systems should be justified…you have to weigh the benefits and the probable harm. The benefit, for security, is very high,” she said.

There are two types of full-body scanner — one which uses high frequency radio waves and one using X-rays — and only the latter machine would expose passengers to the ionizing radiation such as that used in medical X-rays, Czarwinski said.

Although the dosages are small, the inter-agency report said exposures should be carefully monitored.
