摘要：

The Rn-222 emanation fraction (EF) released from the technically enhanced naturally Occurring radioactive material (TE-NORM) wastes at certain sites of petroleum and gas production was determined. The samples were analyzed by gamma-ray spectrometry to determine the activity concentration of the Ra-226 content, of which the Rn-222 emanation fraction was calculated. The results showed that the Rn-222 emanation fraction differs in the oil and gas production sites and it is independent of the activity concentration of Ra-226.
