A rad measures the amount of radiation energy transferred to some mass of material typically humans One roentgen of gamma radiation exposure results in about one rad of absorbed dose Rem Or Roentgen Equivalent Man is a unit that relates the dose of any radiation
The radiation dose absorbed by a person that is the amount of energy deposited in human tissue by radiation is measured using the conventional unit rad or the SI unit gray Gy The biological risk of exposure to radiation is measured using the conventional unit rem or the SI unit sievert Sv
Measuring Radiation There are four different but interrelated units for measuring radioactivity exposure absorbed dose and dose equivalent These can be remembered by the mnemonic R E A D as follows with both common British e g Ci and international metric e g Bq units in use
Radiation Units Roentgen R is a unit of measurement to the exposure of ionizing radiation in air produced from X rays and gamma rays More specifically it is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air Named after German physicists Wilhelm Roentgen who is credited with the discovery of X rays in 1895
