yes, all true, but this is what causes my wife to worry that she will 
come home from work and find a crew in bunny suits outside our house.


When I was an undergrad at UCLA, the local chapter of the Committee to 
Bridge the Gap made radiation measurements on the roof of Boelter Hall 
(wherein there was a decommissioned reactor) and discovered "bigger than 
nominal background" .  Their excitement was tempered when it was 
discovered that the aggregate used in the concrete was granite from from 
the local mountains, which has a moderately high concentration of 
hornblende, and, hence has about double the usual background emissions.
