Naturally occurring radioactive materials (NORM) are found to have high concentration in oil sludge, and special care is required before disposing them. In this study, oil sludge from two oil terminals was incinerated and their environmental radioactivities were monitored. Thermolumi- nescence dosimeters (TLDs) were used to measure accumulated external radiation. The maximum equivalent dose recorded during incineration was 317 µSv/month. The specific activities of Ra-226 in slag, air particulate, discharge water and fly-ash were 34.4 Bq/kg, 4.5 Bq/kg, 4.3 Bq/kg and 0.0053 Bq/m3, respectively. Our results show that incinerating oil sludge is relatively safe to the environment.
