09 Sep 10 - 01:19 PM (#2983244) Subject: BS: Radioactive Aftermath- Japan & the World From: Ebbie After the nuclear blasts at Hiroshima and Nagasaki there must have been fallout that blew around the world. Question: Is there an official, agreed-upon level of radioactivity that made it around the world? How heavy was it? Given the prevailing winds, were there any after-effects suffered by continents and countries and cities next in line and for what length of time were the levels measureable? I'm sure there are people and agencies who have tracked all this but a single question at ask.com didn't give me much information. |

There have been over 300 atmospheric nuclear blasts since 1948. Some of them were above the Stratosphere and ionoshere, some were deep in the sea off San Diego. America was not the sole atmospheric H bomb tester. The leukemia rate for children went up 1000% A single atom of plutonium in your body has the ability to trigger a cancerous response. The Kennedy administration was the last known presidency to have tested above ground. Chernobyl radiocativity did make it worldwide but was worst to the north and west of the plant as far as Denmark and China. |

09 Sep 10 - 02:27 PM (#2983305) Subject: RE: BS: Radioactive Aftermath- Japan & the World From: gnu My old man was in Nevada for some of the tests. He and a handful of others (mostly) RCAF set up the GND (Ground Nuclear Defense) Section and he was an instructor in the basics of same. He told me some things relating to your questions. All tests were followed up with weather observations at all altitudes, for long periods. Radiation was measured at all military US, British, French, Spanish... bases daily. As well, some tests were conducted during specific weather conditions with the intent of measuring high altitude fallout at great distances, particularly eastern US and CA. If you go through the test names you may note that some are names of states or towns. Some tests also had a "sub-name. One was Schooner and the high altitude fallout was specifically "aimed" at Atlantic Canada. They also used herds of sheep placed at varying distances... I'll stop there... you get the drift. Just one more... I was fascinated as a wee lad when he told me of the first test he attended. I don't know what distance they were away but the men were told to shield their eyes with their hands and he saw the bones in his hands. Okay... one more... I was even more fascinated by the fact that he could find a rock, no matter where I hid it, with a gieger counter. |

And that film that was on a thread here about 1945 - 1998, I think... may, the French sure nuked the South Pacific! |

09 Sep 10 - 04:30 PM (#2983415) Subject: RE: BS: Radioactive Aftermath- Japan & the World From: gnu High orbit blasts will be the first to be detonated in a war, but not necessarily nukes. Such blasts can render electic power transmission non-existant depending on various factors. Details are far beyond me. Just a vague memory of what my old man told me. |

09 Sep 10 - 05:30 PM (#2983454) Subject: RE: BS: Radioactive Aftermath- Japan & the World From: bubblyrat I remember reading a "National Geographic" back,I think, in the 1950s, in which there was an item about some fishermen who were found drifting about in their boat, out on the ocean (Pacific ?) and when rescued,they were all sick,with burns on their skin and metallic particles in their hair. It seems that they'd been through a radiation cloud ( without the benefit of "pre-wetting",which they probably didn't know about anyway )and fallout particles had stuck to them. I think it must have been from a British or French nuclear test ; does anyone out there know ?? |
