Air kerma definition
Air kerma means kerma in a given mass of air. The unit used to measure the quantity of air kerma is the Gray (Gy). For X-rays with energies less than 300 kiloelectronvolts (keV), 1 Gray of absorbed dose is delivered by 114 roentgens (R) of exposure.
Air kerma means kerma in air (see definition of Kerma).
Air kerma or “K” means the sum of the initial kinetic energies of all the charged ionizing particles liberated by uncharged ionizing particles per unit mass of air. Kerma is deter- mined as the quotient of dE divided by dM, where dE is the sum of the initial kinetic energies of all the charged ionizing particles liberated by uncharged ionizing particles in air of mass dM. The SI unit of air kerma is joule per kilogram and the special name for the unit of kerma is the gray.
More Definitions of Air kerma
Air kerma or "K" means kerma in air (see definition of "kerma"). "Air kerma rate" or "AKR" means the air kerma per unit time.
Air kerma means the sum of the initial kinetic energy of all charged ionizing particles liberated by uncharged ionizing radiation in a given mass of air. The unit for air kerma is joules per kilogram which is given the special name of gray (Gy). To determine air kerma in Gy from exposure in units of roentgens (R) multiply exposure by the conversion factor 0.00876 Gy/R.
Air kerma. (K) means the kinetic energy released in the mass of a small volume of air by ionizing radiation (see kerma). Air kerma is measured in joules per kilogram (J/kg). For diagnostic x-rays, air kerma is the same as the absorbed dose measured in gray (Gy) delivered to the volume of air in the absence of scatter.
Air kerma means the kinetic energy released by ionizing radiation per unit mass of air. This unit is the gray. The air kerma in gray (mGy) is equivalent to exposure in roentgen (R) multiplied by 8.37 E+2.
Air kerma means kerma in a given mass of air. The unit used to measure the quantity of air kerma is the Gray (Gy). For x-rays with energies less than 300 kiloelectronvolts 9keV), 1Gy=100rad.
