Estimation of committed collective dose equivalents resulting from discharges from the RP-10 research reactor

An environmental investigation was performed on the site of a 10 MW research reactor in Lima, Peru, and on the surrounding area. A simplified environmental model for estimating the effective dose equivalent for critical groups, and the collective dose for the surrounding area (radius 10 km) was postulated. The Gaussian atmospheric dispersion model was adopted. Estimated doses were calculated using gaseous discharges with local transfer parameters as input data. It was demonstrated that, under normal operating conditions, the doses to the critical groups and to the population as a whole are insignificant. (author). 9 refs, 3 figs, 5 tabs
