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 Megarems
The megarem (Mrem) equals 10⁶ rem = 10⁴ Sv. Found in legacy radiation hardness assurance (RHA) documentation for space and military electronics: some total ionising dose (TID) test reports specify doses in Mrem(Si); at Mrem-level equivalent doses all organic structures suffer irreparable radiation damage. 1 Mrem = 10⁴ Sv = 10 kSv.
