Effluents and residual ash were monitored in order to determine the fate of 35S labelled liquid waste during high temperature incineration. Effluents were monitored using a modified EPA approved Method 5 isokinetic sampling probe with 3% H2O2 as the trapping solution. The radioactivity content in the gaseous effluents and residual ash was counted using a liquid scintillation counter calibrated for 35S. Eleven trial burns of liquid waste with activities ranging from 199 to 5659 μCi^1 were conducted. An aqueous solution of 35S labelled Methionine was the source of activity in eight of the trials and an aqueous solution of 35S labeled sulphate was the source in the remaining three trials. Percent of the total activity incinerated contained in the effluents and ash was determined.Master of Science in Public Healt
