   Nov 27, 2014 · RADIATION UNITS Exposure: Roentgen 1 Roentgen (R) = amount of X or gamma radiation that produces ionization resulting in 1 electrostatic unit of charge in 1 cm3 of dry air. Absorbed Dose: rad (Roentgen absorbed dose) = absorption of 100 ergs of energy from any radiation in 1 gram of any material; 1 Gray (Gy) = 100 rads = 1 Joule/kg; Exposure to ...

   What units are used to calculate a radiation dose?

   • Because this value is a calculated approximation, not a physical quantity, it cannot be used to predict individual health effects. The units for effective dose are sievert (Sv, international unit) and rem (rem, U.S. unit). Examples: Use the Radiation Dose Calculator to estimate your yearly dose from sources of ionizing radiation.

   What unit is a material's radioactivity measured in?

   • A material's radioactivity is measured in becquerels (Bq, international unit) and curies (Ci, U.S. unit). Because a curie is a large unit, radioactivity results are usually shown in picocuries (pCi). A picocurie is one trillionth of a curie. The higher the number, the more radiation released by the material. Examples:
