This booklet was written by me in 1969 for the Atomic Energy Commission. It is, of course, totally out of date. It was given away free at the time it was written. What the University Press of the Pacific has done is to claim that this title is in the public domain and with no input from me has republished the same 1969 edition which was some eighty pages and is selling it for a rather high price considering what it is. This practice may or may not be legal depending on what the copyright situation really is-something I am investigating. But is it ethical?
