I ran across an interesting video in the video section of Google, this is the link: http://video.google.com/videoplay?docid=-3626298989248030643&q=genre%3Aeducational+nuclear [Broken] It caught my eye because it was from Hippie News Network. It seemed that the interviewee was hyping the how much we are affected by weapons testing (and to some degree power plants) so I looked up how much weapons added to background radiation exposure, and according to the following paper, the maximum average was 5%. (http://ej.iop.org/links/r8NRKgE1R/ikwqBZFo2xGDvod0av5vpA/jr3102.pdf [Broken]) But, that is an average, it seems to me that a maximum for someone near the testing sites would be higher. Is that information recorded? Interesting lady, as well. I sort of get the feeling she does not have too strong of a background in the nuclear sciences though. A lot of the results from a quick Google were about her talking about DU and Wikipedia said she never published anything in a peer reviewed journal. Near the end of the video she is talking about Pu and U from nuclear weapons, I expected if one is discussing fallout, the fission products would be more important.
