It's a classic false dichotomy. Specifically, a person can care about both issues simultaniously. The problem is that we're not producing the radiation in the air -- it's already there. Radiation shielding is heavy and infeasible for use in current airplane technology. It's a very, very hard problem. BackScatter scanners, in contrast, are optional.
