Bomb Drop Tests(Bomb Functioning Test) are usually conducted nsing bombs assembled in foe conventional manner, an for service usage, but provided with cither inert or simulated fuzes. The target is usually reinforced concrete Refs l)Ordnance proof Manual, Aberdeen Proving Ground, Nos 9—11(1949) Nos 10— 80(1957) 2)PATR l40l,Rev 1(1958)...

Uses of Plutonium. The fissile isotope Pu had its first use in fission weapons, beginning with the Trinity test at Alamogordo, New Mexico, on July 16, 1945, followed soon thereafter by the "Litde Boy" bomb dropped on Nagasaki on August 9, 1945. Its weapons use was extended as triggers for thermonuclear weapons. This isotope is produced in and consumed as fuel in breeder reactors. The short-Hved isotope Tu has been used in radioisotope electrical generators in unmanned space sateUites, lunar and interplanetary spaceships, heart pacemakers, and (as Tu—Be alloy) neutron sources (23). 

The British had proceeded less expeditiously. The Chiefs of Staff advised in October 1945 that the best defence against atomic bombs was likely to be the deterrent effect that the possession of the means of retaliation would have on a potential aggressor, and in January 1946 they said that a stock in the order of hundreds rather than scores would be necessary to deter a country with widely dispersed industries and population (like the Soviet Union). In December 1945, ministers in the Gen 75 committee approved the construction of the first reactor capable of producing plutonium, and in August 1946 the CAS sent the first requisition for an atomic bomb to the Ministry of Supply. The McMahon Act was amended in October 1950 to allow rather more cooperation between American and British scientists but the first British test did not take place until 3 October 1952, in the hold of a ship off Australia. The first test of a British atomic bomb dropped by an aircraft did not occur until 11 October 1956. 

Drop Safety of Bomb Test or Bomb Functioning Test. Drop safety of bomb may be defined as the maximum height of drop for a given bomb oo a given surface without causing the bomb to fail, or without detonation An empirical formula computed at Aberdeen PG before WWII.as a.result of dropping various bombs from an airplane at a height of ca 20 00 ft on 2 ft deep reinforced concrete hard surface laid over a suitable... 

Drop Test from Airplane — Hard Surface Test, Bombs are inert loaded to proper wt and center of gravity. They are released to impact from various heights (not over 10000ft).

TNA shows about the same sensitivity as tetryl in the drop test. Lead block experiments have been reported which showed that 10 grams of TNA produced a net expansion of 430 cc., TNT 254 cc., picric acid 297 cc., tetryl 375 cc., guncotton 290 cc., and 75 per cent dynamite 300 cc.76 Experiments with the manometric bomb gave the results indicated below. 

Most tests involved bombs dropped from aircraft. As the first bombing test, a B24 formation delivered a pattern bombing to the target area, but this test failed because of some mistake made by the Chemical Corps. John Thomas told me that the bombs went into the ground without exploding. Eventually they completed many successful tests and reached significant conclusions (W.A. Noyes, Jr., page 323). 

Static and Aerial Tests with 8-1000 lb Bombs. Two tests have been performed with CC [cyanogen chloride], one in which the eight bombs were placed in a rectangular pattern approximately 200 ft apart and fired statically. In the other, the bombs were dropped from 3000 ft, landing in a pattern somewhat different than that used for the static test but probably comparable to it without serious error. 

In order to simulate the performance of the bomb when dropped firom aircraft, a mortar was constructed at Standard Oil Development Company and used to fire the bombs downward onto a target at any chosen velocity. The mortar was mounted on a movable crane. .. so that the point of impact of the bomb on the structure below could be closely controlled. Various sections of typical enemy domestic and industrial structures were employed to test the penetration, functioning, and fire-raising characteristics of the 6-pound oil bomb.. . Over 20,000 bombs were tested by Standard Oil Development Company before the final design was standardized. [Noyes, page 391]. 

The first atomic bomb was tested at an isolated desert location in New Mexico on July 16,1945. President Truman then issued an ultimatum to Japan that a powerful new weapon could soon be used against them. On August 8, a single atomic bomb destroyed the city of Hiroshima with over 80,000 casualties. On August 11, a second bomb was dropped on Nagasaki with a similar result. The Japanese leaders surrendered three days later. 

DROP TESTS. There are many tests which may be called drop tests. Some of them are conducted by dropping the object to be tested onto a hard surface as for testing bombs, described under Drop Safery of Bomb Test. Testing of projectiles, rockets and qC cojifsincrs is... 

Environmental chemicals were originally associated with cancer through experimental studies in animals. The classic experiment is to repeatedly paint a test substance on the back of a mouse and look for development of both local and systemic tumors in the animal. Likewise, the ability of ionizing radiation to cause human cancer, especially leukemia, was dramatically shown by the Increased rates of leukemia among survivors of the atomic bombs dropped in World War II, and more recently by the increase in melanoma (skin cancer) in individuals exposed to too much sunlight (UV radiation).
