CEDE is expressed in which unit?

Explanation:
CEDE stands for Committed Effective Dose Equivalent, a dose-quantity used to estimate cancer risk from internal radionuclide intake. It is a dose equivalent, not absorbed dose, and in traditional U.S. practice this type of dose was expressed in rem. The rem accounts for radiation type and tissue sensitivity, linking to the concept of dose equivalent. Among the options, rem is the unit historically used for CEDE. In SI terms, the same quantity would be in sieverts (1 Sv = 100 rem, so 1 rem = 0.01 Sv). The other units relate to different concepts: Gray is absorbed dose, Becquerel is activity, and Sievert is the SI unit for dose equivalent.
