How is radiation exposure quantified?

The scientific unit for radiation exposure is the sievert (Sν), though several other types of units do exist. The maximum radiation exposure that is allowable for occupational exposure in the U.S. is 50 millisieverts (mSν). For comparison, the average natural background level of exposure is roughly 3 mSν.
