Terms and definitions in the field of radiological technique. Dose quantities and units. Begriffe und Benennungen in der radiologischen Technik. Dosisgroessen und Dosiseinheiten

Abstract

The standard gives the terms and definitions of concepts, dose quantities and units. The radiation field condition 'secondary electron equilibrium', which forms part of the definition of standard ion dose, is given more precisely. The term 'free in air' is used in its original meaning, i.e. characterization of measuring conditions excluding avoidable stray radiation, which deviates from DIN 6814, part 3/06.72. Dosemeters for measurement of standard ion dose of air kerma are calibrated 'free in air', but this calibration condition is not part of the quantity definition. The quantities standard ion dose or air kerma therefore can also be measured in any other material. The qunatitative relationships between standard ion dose and the quantities 'exposure' and air kerma, as given in the ICRU publication 33 'Quantities and Units' (1980), are explained. The standard introduces the SI units Gray (for energy dose), Sievert (for dose equivalent), and Becquerel (for the activity of a radioactive substance). As the change to the SI units conceals the approximated equality of the numerical values of the standrd ion dose of photon radiation in roentgen, of the energy dose for soft tissue in rad, and of the dose equivalent in rem, new definitions are given in  More>>

As the change to the SI units conceals the approximated equality of the numerical values of the standrd ion dose of photon radiation in roentgen, of the energy dose for soft tissue in rad, and of the dose equivalent in rem, new definitions are given in accordance with ICRU 33 for the quantities specified dose rate, dose rate constant, and area exposure product. These definitions use the terms 'energy dose' and 'kerma'. The dose concepts applied in the field of radiation protection, especially ambient dose and individual dose, are defined as dose equivalents in compliance with the Radiation Protection Ordinance. The relevant sections present information on the conversion of standard ion dose values to the corresponding values of kerma, energy dose, or dose equivalent.}
