Apparently the feds have decided we need more cancer

Except this time it's coming from the DHS instead of the TSA. I guess variety really is the spice of life (or that could just be a mutation in your taste buds causing air to become spicy).

In another classic "one-two" that we've all come to know and love from our government, the DHS has started using a new kind of scanner at border crossings. Never fear, though, this one is safe because its radiation dose is only about "three times the average energy in CT [scans]". This, of course, coming in on the heels of a new study which suggests that CT scans are more dangerous than previously thought.

And I'm sure one isn't supposed to get CT scans that often either. So what about the people that travel across the border frequently?

The impression that I'm getting is that it's kinda like asking the maximum safe "dose" of invasive surgery: zero, unless you need it. So I guess the answer to your question is "don't do that".
