Ecological impacts of explosives are the effects that both unexploded explosives and post-explosion by-products have on the environment. [1] Explosive derived contaminants may have adverse effects on the environmental as well as human health. In addition to their military use in warfare, explosives are also used in construction and demolition.
Overpressure psi (kPa; bar) Effect on buildings and people within 1 (6.9; 0.069) Window glass shatters; Light injuries from fragments occur; 2 (14; 0.14) Moderate damage to houses (windows and doors blown out and severe damage to roofs)
The medical effects of the atomic bomb upon humans can be put into the four categories below, with the effects of larger thermonuclear weapons producing blast and thermal effects so large that there would be a negligible number of survivors close enough to the center of the blast who would experience prompt/acute radiation effects, which were observed after the 16 kiloton yield Hiroshima bomb ...
In the initial microseconds after the explosion, a fireball is formed around the bomb by the massive numbers of thermal x-rays released by the explosion process. These x-rays cannot travel very far in standard atmosphere before reacting with molecules in the air , so the result is a fireball that rapidly forms within about 10 metres (33 ft) in ...
The effect is less for higher frequencies in the microwave region, as well as lasting a shorter time – the effect falls off both in strength and the affected frequencies as the fireball cools and the electrons begin to re-form onto free nuclei. [20] A second blackout effect is caused by the emission of beta particles from the fission products ...
It occurs when a high explosive detonates in a free field: that is, with no surfaces nearby with which it can interact. Blast waves have properties predicted by the physics of waves. For example, they can diffract through a narrow opening and refract as they pass through materials. Like light or sound waves, when a blast wave reaches a boundary ...
The RShG-1 is the more powerful variant, with its warhead having a 10-metre (33 ft) lethality radius and producing about the same effect as 6 kg (13 lb) of TNT. [43] The RMG is a further derivative of the RPG-26 that uses a tandem-charge warhead, with the precursor high-explosive anti-tank (HEAT) warhead blasting an opening for the main ...
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
