How do you feel about MMW vs Backscatter?
Next month, I am taking a trip to PBI(West Palm Beach, FL) I am flying delta out of LGA, which is NOS free. On the return, I am flying Delta out of PBI, which according to TSAStatus.net is MMW Primary for most passengers. A friend of mine just flew through there recently and said they are using the new ATR system. With the ATR, the privacy concerns are gone, and I belive there is no radiation from the MMW, correct? I am leaning twoards being OK with MMW with ATR, but still opting out of non ATR MMW and all Backscatter machines, but wanted to get opinions first?
So is there a diffrence between MMW and Backscatter that makes it big enough for you to use one but opting out of the other? How does the ATR come into play there?
