In 2014 about 7,060 new cases of anal cancer were diagnosed in the United States (4,430 in women and 2,630 in men). [39] It is typically found in adults, average age early 60s. [39] In 2019, an estimated 8,300 adults will be diagnosed with anal cancer. [40] In the United States, an estimated 800 to 900 people die of anal cancer annually. [39]
The human body can survive relatively high blast overpressure without experiencing barotrauma. A 5 psi blast overpressure will rupture eardrums in about 1% of subjects, and a 45 psi overpressure will cause eardrum rupture in about 99% of all subjects. The threshold for lung damage occurs at about 15 psi blast overpressure.
Cancer induction is the most significant long-term risk of exposure to a nuclear bomb. Approximately 1 out of every 80 people exposed to 1 Gray will die from cancer, in addition to the normal rate of 20 out of 80. About 1 in 40 people will get cancer, in addition to the typical rates of 16-20 out of 40.
Since the E1 component of nuclear EMP depends on the prompt gamma-ray output, which was only 0.1% of yield in Starfish Prime but can be 0.5% of yield in low-yield pure nuclear fission weapons, a 10 kt (42 TJ) bomb can easily be 5 * 8%= 40% as powerful as the 1.44 Mt (6.0 PJ) Starfish Prime at producing EMP.
An air burst or airburst is the detonation of an explosive device such as an anti-personnel artillery shell or a nuclear weapon in the air instead of on contact with the ground or target. The principal military advantage of an air burst over a ground burst is that the energy from the explosion, including any shell fragments , is distributed ...
Calculations demonstrate that one megaton of fission, typical of a two-megaton H-bomb, will create enough beta radiation to blackout an area 400 kilometres (250 miles) across for five minutes. Careful selection of the burst altitudes and locations can produce an extremely effective radar-blanking effect. [20]
The visual effects of a high-altitude or space-based explosion may last longer than atmospheric tests, sometimes in excess of 30 minutes. Heat from the Bluegill Triple Prime shot, at an altitude of 50 kilometers (31 miles), was felt by personnel on the ground at Johnston Atoll , and this test caused retina burns to two personnel at ground zero ...
The M107 can be fired more than 10 miles (16 km) and on detonation it produces approximately 1,950 fragments. The M107 was approved for use in 1958 and issued to the army from 1959. Its intended replacement is the M795, manufacture of which began in 1999. The M198 howitzer can fire an M107 up to 18.5 km (11.5 mi) using M4A2 "White Bag" propellant.
