More generally, there is controversy over the use of RAD as a label in the healthcare setting, largely due to the ambiguous definition that the term has. [1] [3] Since RAD is not recognized as a real clinical diagnosis, its meaning is highly inconsistent and may cause confusion and misdiagnosis within the medical community. [1]

This unit is obsolete and no longer clearly defined. One roentgen deposits 0.877 rad in dry air, 0.96 rad in soft tissue, [9] or anywhere from 1 to more than 4 rad in bone depending on the beam energy. [10] These conversions to absorbed energy all depend on the ionizing energy of a standard medium, which is ambiguous in the latest NIST definition.
