An approximate relation for the prediction of the dose rate from radioactivity induced in high energy particle accelerators

If the dose rate from radioactivity induced by high energy particle radiation depends on irradiation time T and decay time T according to D=K0log (T+t/T), where 0 is the flux density of high-energy particles causing the activation and K is a constant for any given set of irradiation, target and geometrical conditions, then this paper shows that K can be estimated such that the formula can be used to make absolute dose rate predictions of sufficient accuracy for radiation protection purposes.
