Review of models for use in probabilistic assessments of the disposal of high level radioactive wastes on or beneath the seabed: appendix III

MARINRAD (MARINe RADionuclide Transport and Dose) is a system of computer programs designed to evaluate the consequences from release of radioactive waste into the ocean. It is presently being used in safety assessment studies for the Subseabed Disposal Program by Sandia National Laboratories. MARINRAD calculates doses to humans and biota and health effects to humans. The MARINRAD software system is composed of three computer programs: ORIGEN, MARRAD and MAROUT. The use of the ORIGEN program to generate a nuclide inventory file is optional. The MARRAD program incorporates an ocean transport box model that calculates radionuclide concentrations as a function of time, and a steady-state food-chain model that calculates the biota concentration factors. Program MAROUT evaluates a pathways-to-man model which is used to calculate dose and health effects to man for up to seven different exposure pathways. (author)
