What is it NORM is naturally occurring radioactive

What is it? § NORM is naturally occurring radioactive material which is deposited in Gas and Oil production systems. § It can be in the form of scales, silts/sludges or very thin deposits on surfaces. § It is impossible to predict where it is going to occur. ﻤﺎﻫﻲ ﺍﻟﻤﻮﺍﺩ ﺍﻟﻤﺸﻌﺔ ﻃﺒﻴﻌﻴﺔ ﺍﻟﻤﻨﺸﺄ ؟ § ﻫﻲ ﻤﻮﺍﺩ ﻤﺸﻌﺔ ﻤﺘﺮﺴﺒﺔ ﻓﻲ . ﺃﻨﻈﻤﺔ ﺇﻨﺘﺎﺝ ﺍﻟﻨﻔﻂ ﺍﻟﻐﺎﺯ § ﻴﻤﻜﻦ ﺃﻦ ﺘﻮﺠﺪ ﻋﻠﻰ ﺸﻜﻞ ﻗﺸﻮﺭ ﺃﻮ ﻃﻴﻦ ﺃﻮ ﺤﻤﺄﺔ )ﺃﻮﺴﺎﺥ ﻤﺘﺮﺴﺒﺔ( ﺃﻮ ﺭﻭﺍﺴﺐ ﻃﻴﻨﻴﺔ ﺃﻮ ﺭﻭﺍﺴﺐ ﺭﻗﻴﻘﺔ ﺠﺪ . ﻋﻠﻰ ﺍﻷﺴﻄﺢ § ﻤﻦ ﺍﻟﻤﺴﺘﺤﻴﻞ ﺍﻟﺘﻨﺒﺆ ﺒﻤﻜﺎﻥ . ﻭﺠﻮﺩ ﻫﺬﻩ ﺍﻟﻤﻮﺍﺩ Translated Draft of Shell UK Exploration and Production presentation package {NORM Training and Awareness} for Approval and Information delivery and understanding only 2

Why is it a hazard. § The naturally radioactive material is concentrated into these deposits. § They become sufficiently active to require precautions to be taken when working with them. They emit alpha, beta and gamma radiation. § They also require to be disposed of in a controlled manner under Omani and International regulations. ﻟﻤﺎﺫﺍ ﺘﻌﺘﺒﺮ ﻫﺬﻩ ﺍﻟﻤﻮﺍﺩ ﺨﻄﺮﺓ ؟ § ﺘﺘﺮﻛﺰ ﺍﻟﻤﻮﺍﺩ ﺍﻟﻤﺸﻌﺔ ﻃﺒﻴﻌﻴﺔ . ﺍﻟﻤﻨﺸﺄ ﻓﻲ ﻫﺬﻩ ﺍﻟﺮﻭﺍﺴﺐ § ﺘﺼﺒﺢ ﻨﺸﻄﺔ ﻟﻠﻐﺎﻴﺔ ﻟﺪﺭﺠﺔ ﺘﺘﻄﻠﺐ ﺍﺘﺨﺎﺫ ﺇﺠﺮﺍﺀﺍﺕ ﺍﺤﺘﺮﺍﺯﻴﺔ ﻋﻨﺪ ﺍﻟﺘﻌﺎﻤﻞ ﻤﻌﻬﺎ ﻭﺘﻨﺒﻌﺚ ﻤﻨﻬﺎ ﺃﺸﻌﺔ . ﺃﻠﻔﺎ ﻭﺒﻴﺘﺎ ﻭ ﺠﺎﻤﺎ § ﻴﺠﺐ ﺍﻟﺘﺨﻠﺺ ﻤﻨﻬﺎ ﻭﻓﻖ ﺇﺠﺮﺍﺀﺍﺕ ﺨﺎﺼﺔ ﺘﺘﻤﺎﺸﻰ ﻤﻊ ﺍﻟﻘﻮﺍﻨﻴﻦ ﺍﻟﻤﺎﻨﻴﺔ . ﻭﺍﻟﻌﺎﻟﻤﻴﺔ Translated Draft of Shell UK Exploration and Production presentation package {NORM Training and Awareness} for Approval and Information delivery and understanding only 3

Radionuclides Found § In dry gas systems restricted to lead-210 and polonium-210 from the Uranium-238 decay series. § In systems where produced water is present the radionuclides beyond radium in both Uranium-238 and Thorium-232 decay series can be found.
