Convert roentgen to tissue roentgen

Roentgen

The roentgen is the traditional CGS unit of radiation exposure, defined as the amount of X-ray or gamma radiation that produces 2.58×10⁻⁴ coulombs of charge per kilogram of air.

Tissue Roentgen

The tissue roentgen is an older unit of radiation absorbed dose, approximately equivalent to the roentgen but defined in terms of energy absorption in tissue rather than air ionization.
