About Sieverts
The sievert (Sv) is the SI coherent unit of equivalent and effective dose, equal to 1 J/kg of absorbed dose weighted by radiation type. Named after Rolf Sievert (Swedish radiophysicist, 1896-1966). Whole-body LD50 for acute exposure ~3-5 Sv; ICRP emergency responder limit 0.25 Sv; acute radiation syndrome threshold ~1 Sv. 1 Sv = 100 rem = 1 J/kg.
About Megasieverts
The megasievert (MSv) equals 10⁶ Sv. Entirely theoretical for biological contexts - severe radiation damage occurs well below 1 MSv. Appears in materials science modelling of extreme radiation environments, theoretical nuclear detonation effects at point of burst, and advanced reactor pressure vessel damage accumulation calculations. 1 MSv = 10⁶ Sv = 10⁸ rem.
