Which non-SI unit is commonly used for dose equivalent?

Explanation:
Dose equivalent is the biological effect-adjusted dose, built from the absorbed dose in gray multiplied by a radiation weighting factor. The SI unit for this quantity is the sievert, but historically a non-SI unit called the rem has been widely used. One rem equals 0.01 sievert (1 Sv = 100 rem). This is why rem is the commonly referenced non-SI unit for dose equivalent. In contrast, gray measures absorbed dose, and becquerel measures activity, not dose.
