Rem
The rem is the old unit of Equivalent Dose
(or more accurately Dose Equivalent
) and is derived by multiplying Absorbed Dose
(in Rads
) by a Quality Factor
. The modern SI unit is the Gray
(Gy). 1 Gy = 100rem. See equivalent dose for a explanation of why the absorbed dose is modified to reflect the relative effectiveness of Ionising Radiations
in causing biological damage.
