What is the CGS unit of absorbed dose?

Absorbed dose is a dose quantity which is the measure of the energy deposited in matter by ionizing radiation per unit mass. Absorbed dose is used in the calculation of dose uptake in living tissue in both radiation protection (reduction of harmful effects) and radiology (potential beneficial effects for example in cancer treatment). It is also used to directly compare the effect of radiation on inanimate matte…

Absorbed dose is a dose quantity which is the measure of the energy deposited in matter by ionizing radiation per unit mass. Absorbed dose is used in the calculation of dose uptake in living tissue in both radiation protection (reduction of harmful effects) and radiology (potential beneficial effects for example in cancer treatment). It is also used to directly compare the effect of radiation on inanimate matter such as in radiation hardening. The SI unit of measure is the gray (Gy) which is defined as one Joule of energy absorbed per kilogram of matter. The older non-SI CGS unit rad is sometimes also used predominantly in the USA.

The measurement of absorbed dose in tissue is of fundamental importance in radiobiology as it is the measure of the amount of energy the incident radiation is imparting to the target tissue. Dose computation The absorbed dose is equal to the radiation exposure (ions or C /kg) of the radiation beam multiplied by 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±0.05 J/C. (33.97 eV per ion pair) Therefore an exposure of 2.58×10 C/kg (1 roentgen ) would deposit an absorbed dose of 8.76×10 J/kg (0.00876 Gy or 0.876 rad) in dry air at those conditions. When the absorbed dose is not uniform or when it is only applied to a portion of a body or object an absorbed dose representative of the entire item can be calculated by taking a mass-weighted average of the absorbed doses at each point. More precisely ${\bar {D_{T}}}={\frac {\int _{T}D(x y z)\rho (x y z)dV}{\int _{T}\rho (x y z)dV}}$ Where Read more on Wikipedia
