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.

About Kilosieverts

The kilosievert (kSv) equals 10³ Sv. Doses above ~10 Sv are rapidly lethal; the kSv scale is encountered only in extreme irradiator calibration measurements, high-energy accelerator beam-loss scenarios, and nuclear detonation effects calculations at the closest survival radii. 1 kSv = 10³ Sv = 10⁵ rem.
