Sellafield has been
discharging radioactive substances into the environment since
1950 when it first began producing fissile materials for nuclear
bombs. Radionuclides such as plutonium-239 and americium-241
have been flushed into the sea - at times unmonitored - while
accidents, particularly the 1957 Windscale Fire, have released
radioactive gases including iodine and polonium to the air.
Such radioactive releases have prompted years of controversy
over how many cancers and deaths might have been caused by Sellafield's
civil and military activities.
