Detail

This report presents an assessment of the radiological impact of routine atmospheric and liquid discharges from UK civil nuclear licensed sites. It updates the previous report, NRPB-R312, in considering discharges in the mid-2000s and using the most recent assessment methodology.

Calculations of collective effective doses integrated to 500 and 100,000 years, typical annual individual doses and per caput-doses were performed for discharges in the mid-1990s and mid-2000s using the updated PC-CREAM 08® software program, which implements the EC methodology for assessing doses from routine releases from nuclear installations.
