Abstract

The Chernobyl accident has led to radioactive contamination of vast Belarussian forest areas. A total scheme for remediation of contaminated forest areas and utilisation of the removed biomass in safe energy production is being investigated in a Belarussian-American-Danish collaborative project. Here the total radiological impact of the scheme is considered. This means that not only the dose reductive effect of the forest decontamination is taken into account, but also the possible adverse health effects in connection with the much needed bio-energy production.

This report presents the results of an in-country, commercial-scale investigation of the effect of a baghouse filter in retaining contaminants so that they are not released to the atmosphere in the biomass energy production process. Approximately 99.5% of the activity of a commercially representative, dust-laden boiler flue gas was removed from the stream by using a combination of a cyclone and a baghouse filter.
