About These Units
Sievert (Sv)
The sievert (Sv) is the SI unit of equivalent dose, measuring biological effect of radiation exposure. Accounts for radiation type via quality factors. 1 Sv = significant health risk, 4-5 Sv = 50% fatality (LD50). Acute exposure above 0.5 Sv causes radiation sickness.
Rem (rem)
The rem (Roentgen Equivalent Man) is the traditional unit of equivalent dose. One sievert = 100 rem exactly. Still used in US nuclear industry and regulations. Annual occupational limit: 5 rem/year. Natural background: 0.3 rem/year. Acute 450 rem ≈ LD50.
