About These Units
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.
Milliroentgen (mR)
A milliroentgen (mR) equals 0.001 roentgen. Radiation survey meters often display mR/h for monitoring X-ray and gamma fields. Natural background: 10-20 mR/year. Typical survey meter range: 0-1000 mR/h.
