The head of the Transportation Security Administration has backed off a public commitment to conduct a new independent study of X-ray body scanners used at airport security lanes around the country.
Earlier this month, a ProPublica/PBS NewsHour investigation found that the TSA had glossed over research  that the X-ray scanners could lead to a small number of cancer cases. The scanners emit low levels of ionizing radiation, which has been shown to damage DNA. In addition, several safety reviewers who initially advised the government on the scanners said they had concerns about the machines being used, as they are today, on millions of airline passengers.
