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 ...
Potassium cyanide is a compound with the formula KCN.It is a colorless salt, similar in appearance to sugar, that is highly soluble in water. Most KCN is used in gold mining, organic synthesis, and electroplating.

The 450 km (280 mi) fallout plume from 15 megaton surface burst Castle Bravo, 1954. "Estimated total (accumulated) dose contours in rads at 96 hours after the BRAVO test explosion" [ 11 ] During detonations of devices at ground level ( surface burst ), below the fallout-free altitude, or in shallow water, heat vaporizes large amounts of earth ...
The term is considered by many safety professionals to be the same as the lower explosive level (LEL). At a concentration in air lower than the LFL, gas mixtures are "too lean" to burn. Methane gas has an LFL of 4.4%. [1] If the atmosphere has less than 4.4% methane, an explosion cannot occur even if a source of ignition is present.
Keenie Meenie Services (or KMS Ltd), was a British private military contractor set up by former Special Air Service (SAS) officers in 1975. It operated as a mercenary force in countries where the United Kingdom had political interests, such as Oman , Uganda , Afghanistan and Sri Lanka .
KMS Fusion was the first private company to attempt to produce a fusion reactor using the inertial confinement fusion (ICF) approach. The basic concept, developed in 1969 by Keith Brueckner , was to infuse small glass spheres with a fuel gas and then compress the sphere using lasers until they reached the required temperature and pressures.
A substance is characterized by a burn rate vs. pressure chart and burn rate vs temperature chart. Higher burn rate than the speed of sound in the material (usually several km/s): "detonation" A few meters per second: "deflagration" A few centimeters per second: "burn" or "smolder" 0.01 mm/s to 100 mm/s: "decomposing rapidly" to characterise it.
