Minor Scale test at the White Sands Missile Range utilized 4880 tons of ANFO to simulate an equivalent airblast of a tactical nuclear weapon. High explosive nuclear effects testing comprises large scale field tests using conventional high explosives as alternatives to atmospheric nuclear testing.
Nuclear test detection experiments are designed to improve the capabilities to detect, locate, and identify nuclear detonations, in particular, to monitor compliance with test-ban treaties. In the United States these tests are associated with Operation Vela Uniform before the Comprehensive Test Ban Treaty stopped all nuclear testing among ...
The underlying principle is, under conditions of stress, diseased myocardium receives less blood flow than normal myocardium. MPI is one of several types of cardiac stress test. As a nuclear stress test, the average radiation exposure is 9.4 mSv, which when compared with a typical 2 view chest X-ray (.1 mSv) is equivalent to 94 Chest X-rays. [83]
First nuclear weapons test, conducted as part of the Manhattan Project. Tested the Mark 3 Fat Man design. Crossroads: 1946 2: 2: 2: 21 42: First postwar test series. Sandstone: 1948 3: 3: 3: 18 to 49 104: The first use of "levitated" cores made of oralloy. Tested components for Mark 4 design. Ranger: 1951 5: 5: 5: 1 to 22 40: First tests at the ...
The low estimates on the yield of the test—potentially less than a kiloton in strength—have led to speculation as to whether it was a fizzle (unsuccessful test), or not a genuine nuclear test at all. On May 25, 2009, North Korea announced having conducted a second nuclear test.
World anthropogenic background radiation levels peaked at 0.11 mSv/yr above natural level of 2.40 mSv/yr in 1963, the year that the Partial Nuclear Test Ban Treaty was enacted. This was a 4.6% increase above normal background radiation exposure. Since then, by about 2008, anthropogenic background radiation has decreased to 0.005 mSv/yr above ...

The stress test can result in three outcomes: Pass, Partly Pass and Fail, based on the comparison of the quantified risks to acceptable risk exposure levels and a penalty system. Phase 3: Decision, during which the results of the stress test are analyzed according to the goal and objectives defined in Phase 1. Critical events (events that most ...
