DHS' X-ray Car Scanners Now At Border Crossings

OverTheGeicoE (1743174) writes "CNET has a story on DHS' whole car X-ray scanners and their potential cancer risks. The story focuses on the Z Portal scanner, which appears to be a stationary version of the older Z Backscatter Vans. The story provides interesting pictures of the device and the images it produces, but it also raises important questions about the devices' cancer risks. The average energy of the X-ray beam used is three times that used in a CT scan, which could be big trouble for vehicle passengers and drivers should a vehicle stop in mid-scan. Some studies show the risk for cancer from CT scans can be quite high. Worse still, the DHS estimates of the Z Portal's radiation dosage are likely to be several orders of magnitude too low. 'Society will pay a huge price in cancer because of this,' according to one scientist."

This could be real trouble for cancer survivors (0)

My wife was treated for an aggresive form of breast cancer, with equally aggressive chemo and radiation. The doctors told her she'd had her lifetime dose of radiation in that treatment. She's to avoid any source of radiation she possibly can, notably including opting out of the TSA's nude scans. If one of these things gives here the once-over, it could be disastrous. What's worse it that there are reports of them roaming the streets [] , so you have no chance to decline.
