1. True but our industry has done a poor job of public education.
2. Many basements are much higher dose from radon than the exposure in most of the restricted land but not all.
1. Most of the 'lack of public education' stems from the 50's - 70's (and even now) equation of nuclear power to nuclear weapons, i.e., one and the same. Even in the early days the 'Admiral' didn't want a whole lot said because of the equation, a practice still followed in the industry today.
2. Many public buildings, particularly in DC, built from stone, have higher dose from a typical work day than a lot of nuclear facilities!
In the early 80's we had a particularly anti-nuke reporter, where I lived. The utility took the opportunity to send him to a class in OR (at the expense of the utility). He became a supporter and very pro-nuke in responding to anti statements and publications. Unfortunately, we as an industry, didn't take an active 'public education' role years ago!
