Unformatted text preview: nuclear disintegration per second. Beta Particle: A charged particle emitted from a nucleus during radioactive decay. The beta particle, with a mass equal to 1/1837 that of a proton, is similar to an electron. Large amounts of beta radiation may cause skin burns, and beta emitters are harmful if they enter the body. Beta particles from radioactive decay are easily stopped by a thin sheet of metal or plastic. Blast Effect: A pulse of air in which the pressure increases sharply at the front, accompanied by winds, propagated from an explosion. Boiling Water Reactor (BWR): A type of reactor system which allows water to boil directly in the reactor core to produce steam for the turbine generator. Central Nervous System: The body's organ system that originates, sends, and receives electrical signals to control movement and action. Acute exposures of over 2,200 R cause death within hours by damage to this organ system....
