WebThe SI unit of radiation dose is "gray" (Gy) which is radiation equivalent to 1 J/kg. A small energy delivered as ionizing radiation can create huge damage at the cellular level, and the sievert is a unit of the health effect of radiation proportional to the radiation dose, but multiplied by factors allowing for the absorption and and the nature of the radiation. WebFeb 25, 2005 · A. A conversion from counts per second (cps) to dose rate (Gy h -1, Sv h -1, etc.) is possible, but the conversion factor depends on the kind of detector being used and on the type of radiation being measured and frequently on the energy of the radiation. The relationship between count rate and dose rate is usually established through empirical ...
