Biography
Ezeddine Hamida graduated with BSc Degree in Physics from Tripoli University(Libya) in 1996, in 2010 completed his MSc in Radiation and Environmental Protection (REP) from University of Surrey (UK). He has number of training courses and approved certificates in training and communication skills. He is a professor of physics and fluid mechanics since 2001 for PTQI (Petroleum Training and Qualifying Institute-Tripoli-Libya) and as a collaborator for some Libyan Universities since 2011. He was a founder of Fluid Mechanics Lab and author of methodic book of Fluid Mechanics Lab for PTQI in 2003 , he has10 years experience as a supervisor of Fluid Mechanics Lab. He participated by scientific papers locally and international in NORM area (Tripoli 2014 - Budapest 2016). He published scientific paper entitled “Quantifying the Nuclear Slow-Process via Neutron Activation†in the scientific journal “Alnawa †which issue from Center of Nuclear Research-Tajoura in 2015, and scientific article entitled “ Nuclear Techniques at service of Oil & Gas Industry†in the scientific bulletin “The Atom and Development†which issue by aaea (Arabic Atomic Energy Agency) was published in June 2016.

Abstract
This paper is the second part of a comprehensive research, its goal is to create a database about the existence of the NORM (Naturally Occurring Radioactive Material) in Petroleum Fields, Terminals & Gas Export Stations across Libya, the NORM was measured in two oil ports (Al-Hariqa Port –Tobruk, east of the country, and Zawia Port, west of the country) where oil is exported therefrom, which is coming from two oilfields in which a relatively high proportion of radiation in scales’ samples was recorded (the first part of the research, which was presented in -RANC2016- Budapest) in order to try to track the spread of pollution resulting of the Scales’ NORM and make sure the possibility of arriving at the ports . The results were as follows: : \r\n\r\nActivity concentration recorded in thewaters of Al-Hariqa port Activity concentration recorded in the scales sample in the field connected to the Port Al-Hariqa Activity concentration recorded in the waters of Zawia port Activity concentration recorded in the scales sample in the field connected to the Zawia \r\nPort\r\n26.6± 5.15(Bq / L) 5522.6±74.31 (Bq /kg) 19.9±4.46 (Bq / L) 4017.2±63.38 (kBq / kg)\r\nTable (1)\r\n \r\n(P.S.: There was no reference to the name of fields upon the request of officials of these fields)\r\n\r\nThe NORM was also measured in some commercial ports so as to compare the NORM levels in each of the Petroleum Ports and the Commercial ones. The results were as follows:\r\n\r\nThe Port Port Rating Activity concentration(Bq/L) \r\nZawia Port Petroleum 19.9±4.46\r\nPort of Tobruk(Al-Hariqa) Petroleum 26.6±5.15\r\nKhoms port commercial 15.9±3.98\r\nMisrata port commercial 33±5.74\r\nPort of Tripoli commercial 8±2.8\r\n Table(2)\r\n\r\nFrom the results, it is clear that the NORM levels in oil ports & Commercial ones is within the allowed limits(Exemption level). Samples were of 1.5 liters of water taken from the ports’ basins where the oil tankers are shipped in shipping oil ports at the shipping & discharge basins into the commercial ports. Gamma Ray which was emitted from the samples was measured by High pure Germanium Detector –HPGe at the Radiation Prevention Department in Tajura Nuclear Research Center-Tripoli, Libya.\r\n
