What is radiation dose?
Equivalent dose measures the biological effect of ionizing radiation. The SI unit is the sievert (Sv); the older unit is the rem.
FormulaSv = 100 rem
Key conversions
- 1 sievert (Sv) = 1,000 millisieverts (mSv) = 100 rem
- 1 rem = 10 millisieverts (mSv)
- 1 mrem = 0.01 millisieverts (mSv) = 10 microsieverts (µSv)
- 100 mrem = 1 rem
- 1 mSv = 1,000 microsieverts (µSv)
