Introducing DEPDOSE, a Tool to Calculate Dose Coefficients to Members of the Public for Radioactive Aerosols

This paper presents DEPDOSE, an open-source computer application that combines the KDEP respiratory tract deposition fractions for inhaled aerosols with DC_PAK committed equivalent dose coefficients for a unit deposition in each region of the respiratory tract. DEPDOSE allows the user to rapidly produce tables of dose coefficients for workers and members of the public inhaling precisely defined, user-specified aerosols using the ICRP Publication 60 methodology. Combined with a plume dispersion modeling system, such as the Quick Urban & Industrial Complex (QUIC) Dispersion Modeling System, this makes it possible to predict radiation doses downstream from an accidental or intentional release of radioactive materials. For this work, a radioactive plume was calculated to members of the public downstream from a dirty bomb in Chicago.
