Dose equivalent is expressed in which units?

Explanation:
Dose equivalent accounts for the varying biological impact of different radiations by weighting the absorbed dose with a radiation quality factor. This produces a measure of risk that is expressed in rem (traditional) or sievert (SI). Absorbed dose by itself is energy deposited per mass and is measured in rad or gray, not dose equivalent. Energy units like joule or watt, and activity units like curie or becquerel, don’t convey the radiation’s biological effect. So, the dose equivalent uses rem or sievert.
