2. Roentgen
   The roentgen is a unit used to measure radiation exposure. This canonly be used to describe an amount of gamma and X-rays, and only in air. Oneroentgen is equal to depositing in dry air enough energy to cause 2.58x10^-4 coulombs kg^-1.It is a measure of the ionizations of the mol...

17. roentgen
    Unit of radiation exposure, used for X-rays and gamma rays. It is defined in terms of the number of ions produced in one cubic centimetre of air by the radiation. Exposure to 1,000 roentgens gives rise to an absorbed dose of about 870 rads (8.7 grays), which is a dose equivalent of 870 rems (8.7 sieverts)
