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.
About Rems
The rem (roentgen equivalent man) equals exactly 0.01 Sv = 1 cSv. The pre-SI unit of equivalent dose, still dominant in US regulation: NRC occupational whole-body limit 5 rem/year; 10 CFR Part 20 exposure limits cited in rem; US military personnel dose records maintained in rem. 1 rem = 0.01 Sv = 1 cSv.
