Radiation converters offer conversions of the radiation source activity, radiation exposure, radiation absorbed dose, and radiation equivalent dose units.
The radiation source activity converter offers conversion between different radiation source activity units. The radiation source activity is measured in Becquerel [Bq] (SI unit) and is defined as the number of radioactive transformations per second that occur in a particular radionuclide. In literature, it can be found an older non-SI unit of activity called curie [Ci] where 1 [Ci] is equal to \(3.7 \times 10^{10}\) transformations per second.
The radiation exposure converter offers conversion between various radiation exposure units. The SI unit for radiation exposure is coulomb per kilogram \(\left[\frac{\mathrm{C}}{\mathrm{kg}}\right]\). Radiation exposure is the measure of the ionization of air due to ionizing radiation from photons (gamma rays and X-rays). The radiation exposure is defined as the electric charge freed by radiation in specified volume of air which is divided by the mass of that air. Besides commonly used \(\left[\frac{\mathrm{C}}{\mathrm{kg}}\right]\) unit there is roentgen [R] unit used to measure radiation exposure.
Radiation absorbed dose converter offers conversion between various radiation absorbed dose units. The radiation absorbed dose or absorbed dose is the measure of the deposited energy in the matter by ionizing radiation per unit mass. The absorbed dose measure is used in the calculation of dose uptake in living tissue in radiation protection, and radiology. The SI unit for absorbed dose unit is gray [Gy], which is a derived unit and is equal to Joule per kilogram \(\left[\frac{\mathrm{J}}{\mathrm{kg}}\right]\). Besides [Gy] the [rad] unit is also used which is older non-SI CGS unit.
Radiation equivalent dose converter offers conversion between various equivalent dose units. The radiation equivalent dose or shortly equivalent dose is a dose H that represents the stochastic health effects of low levels of ionizing radiation on the human body; that represents the probability of cancer and genetic damage. The equivalent dose is derived from the absorbed dose, however, it takes into account the biological effect of radiation (radiation type and energy). The SI unit for absorbed dose is Sievert (Sv) which is a derived unit and is equal to Joule [J] per kilogram [kg] \(\left[\frac{\mathrm{J}}{\mathrm{kg}}\right]\).
