"TSA's response lacked any detail as to why the agency no longer believes an independent study on the health effects of X-ray backscatter machines is warranted, nor did it explain how the IG's review would be a sufficient substitute for an independent study," Collins said. "That is why I have introduced this bill today."
Collins said her bill was also prompted in part by the story of a pregnant woman who unknowingly went through an X-ray scanner at an airport, then miscarried.
"Only two weeks later, she suffered a miscarriage which she attributes to the radiation she received from this scan," Collins said. "We will never know for certain the cause of this family's loss, but they believe in their hearts that the backscatter radiation is to blame."
