Total body disruption is the most severe and invariably fatal primary injury. [2] Primary injuries are especially likely when a person is close to an exploding munition, such as a land mine. [3] The ears are most often affected by the overpressure, followed by the lungs and the hollow organs of the gastrointestinal tract.
Although tetryl is among the most toxic explosive compounds, it is very short-lived. This combined with the fact that the health impacts of this compound are largely unstudied, not much is known about any health problems that this compound may cause. Epidemiological data shows that tetryl has most effect on the skin, acting as a strong irritant ...
In the event of a nuclear attack, a human body can be irradiated by at least three processes. The first, and most significant, cause of burns is thermal radiation and not caused by ionizing radiation. Thermal burns from infrared heat radiation, these would be the most common burn type experienced by people.
These waves mostly damage junctions between tissues of different densities (bone and muscle) or the interface between tissue and air. Lungs and the abdominal cavity, which contain air, are particularly injured. The damage causes severe hemorrhaging or air embolisms, either of which can be rapidly fatal. The overpressure estimated to damage ...
The generation of heat in large quantities accompanies most explosive chemical reactions. The exceptions are called entropic explosives and include organic peroxides such as acetone peroxide. [6] It is the rapid liberation of heat that causes the gaseous products of most explosive reactions to expand and generate high pressures. This rapid ...
The chemical reaction produces heat and pressure, and some beetles exploit the latter to push out the chemicals onto the skin; this is the case in the beetle Metrius contractus, which produces a foamy discharge when attacked. [14]
A high explosive violent reaction (HEVR) includes reactions ranging from a fast deflagration of the high explosive (HE), up to and including a detonation of the high explosive. The explosive wave may be subsonic or supersonic.
A contact explosive is a chemical substance that explodes violently when it is exposed to a relatively small amount of energy (e.g. friction, pressure, sound, light). Though different contact explosives have varying amounts of energy sensitivity , they are all much more sensitive relative to other kinds of explosives.
