Absorbed dose
Absorbed dose is a measure of the energy deposited in a medium by ionizing radiation per unit mass. It is equal to the energy deposited per unit mass of medium, which may be measured as joules per kilogram and represented by the equivalent SI unit, gray, or the antiquated CGS units, rad and rep. The absorbed dose depends not only on the incident radiation but also on the absorbing material: a soft X-ray beam may deposit four times more dose in bone than in air, or none at all in a vacuum. The absorbed dose is equal to the kerma of the radiation beam times the ionization energy of the medium to be ionized. For example, the ionization energy of dry air at 20°C and 101.325 kPa of pressure is 33.97 ± 0.06 J/C. Therefore a beam kerma of 2.58×10^-4 C/kg would deposit an absorbed dose of 8.76×10^-3 J/kg in dry air at those conditions. Absorbed dose is used to rate the survivability of electronic components to nuclear environments, to gauge the risk of acute radiation syndrome, and as an intermediate figure in dosimetry calculations. The absorbed dose alone is not an adequate indicator of the likely health effects in humans. Consideration must also be given to the type of radiation, the dose rate, the affected tissues, and other factors. For example, 1 Gy of alpha radiation would carry a much greater risk of cancer than 1 Gy of photon radiation. Further calculation can be performed to find the equivalent dose for whole body external exposure, the effective dose for partial body external exposure, or the committed dose for internal exposures. These adjusted doses, measured in units of sievert or rem, are much more representative of the stochastic risks to human health.
