Abstract: In this work, we have measured specific activity in ten motor oil samples for ten origins taken from the local markets by using high purity germanium (HPGe) detector. The results obtained have shown that the highest values of specific activity of (U-238, Th-232 and K-40) which was equal to (22.520 Bq/l, 26.640 Bq/l and 221.340 Bq/l), for [(Rasheed) sample (Iraq origin), (Noblu) sample (Iran origin) and (Maas) sample (Netherland origin)], respectively, while the lowest values of specific activity for (238U,232Th and 40K) was found in (Jopetrol) sample (Jourden origin) which was equal to (12.340 Bq/l, 11.450 Bq/l and 97.530 Bq/l), respectively, the paper consider is the first study in Iraq to measured specific activity for motor oil samples.
