Uncontrolled disposal of produced water from oil and gas industry in the
environment involves the environmental hazard like contamination soil by NORM and
increase the radiation exposure to terrestrial gamma radiation by workers and public. the
st
udy aims to measure radiation levels in the drainage zone and vicinity in the field of
crude oil storage tanks in the site of Syrian company for oil transport in Banyas. Terrestrial
gamma radiation dose was measured, the values ranged between 0.02 – 0.24 μSv.h-1. The
radioactivity concentrations of NORM were determined for Ra226, Th232, K40 by gamma
spectroscopy using HPGe detector in surface soil samples taken from three sites, two of
them recorded the highest rate of radiation dose, while the third recorded the rate of
radiation background. The Ra226, K40, Th232highestconcentrations in the soil samples were
found to be 210, 213 and 55.9 Bq.kg-1, respectively. Radiation indexes were estimated.
The present results were compared with results published in different countries.
