Here's a bit of shocking news. Okay, it's not shocking at all. Maybe this is the least shocking news this week. From ProPublica:

The Transportation Security Administration says its full-body X-ray scanners are safe and that radiation from a scan is equivalent to what's received in about two minutes of flying. The company that makes them says it's safer than eating a banana..

But some scientists with expertise in imaging and cancer say the evidence made public to support those claims is unreliable. And in a new letter sent to White House science adviser John Holdren, they question why the TSA won't make the scanners available for independent testing by outside scientists.

By the way, about those bananas? I visited the TSA headquarters cafeteria once. The bananas they sell are the delicious Fukushima variety.
