Experimental and computational determination of the dose characteristics of a standard source of γ-radiation

The absorbed dose in a calorimeter is compared with Monte Carlo calculations for a standard source of exposure dose of γ-radiation from 60 Co. It is shown that if the initial γ-radiation spectrum is known to a high degree of accuracy, then a mathematical model of the interaction of particles and γ-r...

Description
Summary:The absorbed dose in a calorimeter is compared with Monte Carlo calculations for a standard source of exposure dose of γ-radiation from 60 Co. It is shown that if the initial γ-radiation spectrum is known to a high degree of accuracy, then a mathematical model of the interaction of particles and γ-rays with matter can be used to calculate the absorbed dose in a detector and the exposure dose in air to within several percent. This makes it possible to develop an experimental-computational method of transferring the dimensional units for the exposure dose and dose rate from a static standard to working means of measurement and pulsed bremsstrahlung sources.
