Science Lessons by FTCua 5/28/08


read up on the different radiation measurement techniques then; my MS in Radiation Science thesis was on the comparison of radiation measurement techniques at five high energy accelerator facilities including CERN PS

there is a NOVA series and I am waiting to watch the new ones...

more later; why don't you ponder on these: some of the nuclear weapon testings cause earthquakes and/or tsunamis

Nuclear Weapons Test Map

Since 1945 there have been a total of 2,057 known nuclear tests worldwide. The United States and the former Soviet Union conducted the majority of these with the U.S. performing 1,030 tests from 1945 - 1992 and the Soviet Union carrying out 715 between 1949 and 1990. In 1963 both the Soviet Union and the United States signed the Limited Test Ban Treaty which prohibited nuclear weapons tests in the atmosphere, in outer space, and underwater. Additionally, the treaty banned underground tests that would cause "radioactive debris to be present outside the territorial limits of the State under whose jurisdiction or control" the explosions were conducted.

Alaska (US) -- 3 Tests
Johnston Island (US) -- 12 tests
Christmas Island (UK & US) -- 30 tests
Malden Island (UK) -- 3 tests

Nevada (US) -- 935 tests
Colorado (US) -- 2 tests
New Mexico (US) -- 2 tests
Mississippi (US) -- 2 tests
South Atlantic Ocean (US) -- 12 tests
Algeria (France) -- 17 tests
Russia (USSR) -- 214 tests (many at Novaya and Zemlya)
Ukraine (USSR) -- 2 tests
Kazakhstan (USSR) -- 496 tests
Uzbekistan (USSR) -- 2 tests
Turkmenistan (USSR) -- 1 test
Pakistan (Pakistan) -- 2 tests
India (India) -- 4 tests
Lop Nur (China) -- 41 tests
Marshall Islands (US) -- 66 tests
Australia (UK) -- 12 tests
In September, 1996 the United Nations General Assembly voted to adopt the Comprehensive Nuclear Test Ban Treaty, which prohibits all "nuclear weapons test explosions and all other nuclear explosions." As of September 1998, 150 nations had signed the treaty, and 21 nations had ratified it. Notable exceptions are India and Pakistan, both of which conducted nuclear tests in May, 1998.
