Environmental survey at the Lucas Heights Research Laboratories, 1981

Abstract

This survey of environmental conditions in the neighbourhood of the Lucas Heights Research Laboratories during 1981 indicates no significant radiological hazard to the general public. This result is consistent with the fact that controlled airborne and liquid effluent releases throughout the year were maintained within the authorised limits and also indicates that there were no significant accidental releases. Residual cobalt-60 and zinc-65 activity in the Woronora River has decreased since the cessation of controlled liquid effluent discharges in 1980. No trends are obvious in any of the data which could lead to future problems from continued operation on the present scale.
