I don't want to put my baby daughter through a scanner, pure and simple. Studies can say many things (and in this case, they do), but we won't know the true effect of this largely untested family of (lucrative and rushed to market) technologies for 20 years.There are clear shortcomings evident in many of the "its safe" studies (such as the testing which uses volumetric radiation measurements while the technology doesn't pass through (suggesting much higher concentration at a lower depth)).
Short answer: I think all of us (with children) would prefer our children to opt out of the the complimentary skin cancer and just get the college diploma at 21.
