Surveillance of tritium in the environment
This paper is a report on the monitoring of tritium in oxide from HTO in the environment near the ESSOR reactor, which was placed in long term shutdown in 1982. Continuous monitoring has since been carried out to verify that gaseous or liquid emissions from the plant remain within acceptable limits. A measurement programme begun in 1977 for surface water was later extended to vapours in the air, to deep water and finally to water recovered from milk produced at a local farm. By examining experimental half-life values for concentrations in water from these sources and comparing them with similar data for surface water in the Federal Republic of Germany and with concentration trends in atmospheric precipitation it can now be established that liquid and gaseous emissions from the plant have had no effect (or only a negligible effect) on tritium concentrations in the environment of the Ispra site. This means that the levels measured are the result of remnants from atmospheric weapons tests from 1950-1960 combined with emissions from nuclear facilities still operating.
