Validation of the atmospheric transport model: comparison of observed krypton-85 concentrations with those computed using a Gaussian plume model

Thirty monthly average 85Kr concentrations measured at 13 sampling locations between 25 and 150 km from a quasi-continuous point source were used in a validation study of the Atmospheric Transport Model for Toxic Substances (ATM-TOX). Although the computed values tended to overestimate, more than 60% of them fell within a factor of 2 of the observed concentrations
