Full-Body Scanners to Fry Travelers With Radiation
"Officials must naturally defend compulsory passenger X-rays as harmless. But they are signing no guarantees because ionizing radiation in the X-ray spectrum damages and mutates both chromosomal DNA and structural proteins in human cells. If this damage is not repaired, it can lead to cancer. New research shows that even very low doses of X-ray can delay or prevent cellular repair of damaged DNA, raising questions about the safety of routine medical X-rays. Unborn babies can become grotesquely disfigured if their mothers are irradiated during pregnancy. Heavily X- rayed persons of childbearing age can sustain chromosomal damage, endangering offspring. Radiation damage is cumulative and each successive dose builds upon the cellular mutation caused by the last. It can take years for radiation damage to manifest pathology."
