Mercury (element) is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alternatives such as alcohol- or galinstan-filled glass thermometers and thermistor- or infrared-based electronic instruments. Likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. Mercury remains in use in scientific research applications and in amalgam for dental restoration in some locales. It is also used in fluorescent lighting. Electricity passed through mercury vapor in a fluorescent
Gyeongju nuclear waste disposal facility and inspections required to enforce the policies set in place by the M.O.S.T., as well as setting standards for safety, is the KINS: Korea Institute of Nuclear Safety. The Nuclear Safety Commission (NSC), a branch within the KINS, has the task of being the decision making body on nuclear safety and regulatory policies, as well as licensing. Gyeongju nuclear waste disposal facility The Gyeongju nuclear waste disposal facility is of silo-type design involving disposal at depth meant to safely house dangerous radioactive waste at Gyeongju in South Korea. Storage of Low to Intermediate Level Waste (LILW) was planned. In its
