Heathrow Body Scanners & Cancer

exposure to x-rays can lead to leukaemia , cancer of the bone marrow. The plan for broad use of X-ray body scanners to detect bombs or weapons under airline passengers clothes has rekindled a debate about the safety of delivering small doses of radiation to millions of people — a process some experts say is certain to result in a few additional cancer deaths. The scanning machines, called backscatter scanners, deliver a dose of ionizing radiation equivalent to 1 percent or less of the radiation in a dental X-ray. The amount is so small that the risk to an individual is negligible, according to radiation experts. But collectively, the radiation doses from the scanners incrementally increase the risk of fatal cancers among the thousands or millions of travelers who will be exposed, some radiation experts believe. The guiding principle is not whether Mother Nature is going to kill you one day, said Arjun Makhijani, a nuclear physicist. Its whether we can justify doing something to each other based on the benefit
