A jacket of 75 As, irradiated by the intense highenergy neutron flux from an exploding thermonuclear weapon, would transmute into the radioactive isotope 76 As with a half-life of 1.0778 days and produce approximately 1.13 MeV gamma radiation, significantly increasing the radioactivity of the weapon's fallout for several hours. read more

Arsenic is a chemical element that has the symbol As and atomic number 33. Its position in the periodic table is shown at right. This is a notoriously poisonous metalloid that has many allotropic forms; yellow, black and gray are a few that are regularly seen. Arsenic is not found free in nature, but its compounds are widely distributed in minerals. read more

Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the second most commonly used semiconductor after doped silicon. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. read more
