Description

Assessments of the levels of radioactivity in sludge from the Brent Spar storage tanks have been performed. Based on field and laboratory measurements, only 44 drums (of a total of 2268 drums) were identified as drums with 226Ra concentrations above the exemption level of 10 Bq/g given by the Authorities. Field measurements showed satisfactorily agreement with laboratory measurements. The drums containing radioactivity concentrations below the exemption level were classified as non-radioactive and shipped to Sloevaeg Industriservice AS for incineration. Only small amounts of radioactivity were found in the ashes after incineration. The concentrations in the offgas and the outlet water were below or close to the detection limit for gamma spectrometry. Incineration of sludge with activity concentrations below the exemption level was found to be a well-suited method for disposal. (orig.)
