[ RadSafe ] Testing bombs

[Steven Dapra]

June 28, 2008

	From time to time I have read that one of the Hiroshima and Nagasaki bombs 
had to be tested before it was used, and that one did not --- that the 
engineers were so certain the latter bomb would explode that they didn't 
bother testing it.  I also read recently that hydrogen bombs must be 
tested.  Of these three types of bombs, which ones must be tested, and 
why?  For the one that did not have to be tested, why not?  (I don't have 
any bombs I want to test, I am merely curious.)
