NORM Naturally occurring radioactive material (NORM): Is radiation
NORM Naturally occurring radioactive material (NORM): Is radiation that exists naturally in the environment Is also known as background radiation Has many sources, such as soil and rocks Can be found in things like tap water, cigarettes, and smoke detectors PPT-SM-N 2017
2 Radiation becomes dangerous when it becomes concentrated in some way by human activity. Technically enhanced NORM (TENORM) is radioactive material disturbed and concentrated by human activities, such as drilling for oil. TENORM is often used interchangeably with NORM.
PPT-SM-N 2017 3 NORM is a serious health risk because high levels of radiation can cause cancer. You must protect yourself when you work in an area contaminated with NORM. NORM exposure mostly happens through inhalation or ingestion. PPT-SM-N 2017
4 There are two types of exposures to radiation, acute and chronic: Acute exposure is when a very large amount of radiation is suddenly released Chronic exposure is exposure to low levels of radioactivity over a long period of time PPT-SM-N 2017
5 Workers in the oil and gas industry encounter NORM when they tap NORM deposits within shale. NORM can be produced as waste water and can take the form of scale buildup in: Tubulars Wellheads Flowlines
Pits Drill pipes PPT-SM-N 2017 6 NORM is typically encountered at older manufacturing centers with old equipment and abandoned wells. NORM contamination may spread when the old equipment is recycled as scrap metal.
PPT-SM-N 2017 7 The three most basic ways to protect yourself from radiation include time, distance, and shielding: Time Limit your time around radiation and remove yourself from the source if possible
Distance If you are aware of a radioactive source, try to stay as far away as possible Shielding Shield yourself and put a shield around the source of the radiation for the best protection PPT-SM-N 2017 8
Good work practices and engineering controls that can be used to protect workers from harmful radiation include: Using filtered ventilation via high-efficiency particulate absorption (HEPA) filters Posting radioactive material signs around restricted areas to keep unauthorized personnel out Monitoring workers occupational dose intake to make sure they are not close to the
occupational dose limit PPT-SM-N 2017 9 Radiation areas will be boldly labeled with radioactive materials (RAM) signs. When you see an area with a RAM sign, do not eat or drink in that area.
PPT-SM-N 2017 10 Exposure to NORM must be kept as low as is reasonably achievable. Your company should have a radiation protection program outlined in its policies and procedures. PPT-SM-N 2017
11 Jobsites should be monitored for radiation before work begins. Monitor the air and equipment to create a baseline of radioactivity. PPT-SM-N 2017 If any source of radioactivity is found, immediately
report the source to your supervisor. 12 If significant levels of NORM are found, workers should be medically evaluated to determine their existing occupational dose of radiation.
PPT-SM-N 2017 13 Respiratory protection may be needed in NORM-contaminated areas if engineering controls cannot keep the airborne radioactivity levels below the exposure limits. PPT-SM-N 2017
14 Two types of respirators may be used when dealing with NORM: Half-face respirators with HEPA cartridges Supplied air respirators (SARs) PPT-SM-N 2017 15 Wear appropriate PPE for the job, such
as gloves, aprons, and hard hats. If appropriate PPE is unavailable or damaged in any way, do not work in the restricted area. PPT-SM-N 2017 16 NORM is a serious health risk to workers in the oil and gas industry. You must protect yourself when you work in an area contaminated with NORM.
Exposure to NORM must be kept as low as is reasonably achievable. Your company should have a radiation protection program outlined in its policies and procedures. PPT-SM-N 2017 17 Copyright 2016 by PEC/Premier Safety Operations, LLC
