When it comes to working in the oil and gas industry, safety is of the utmost importance. One of the unique concerns in this field is the presence of naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM). In this blog post, we’ll take a closer look at what NORM and TENORM are, where they come from, the level of radiation associated with them, and how we can safely manage and dispose of them.
First, let’s define what NORM and TENORM are. NORM refers to materials that contain naturally occurring radioactive elements, such as uranium, thorium, and radium. These materials can be found in the earth’s crust and can be present in a variety of forms, including rock, soil, and water. TENORM, on the other hand, refers to materials that have become contaminated with NORM as a result of human activities, such as oil and gas production, mining, and industrial processes.
One of the key differences between NORM and TENORM is the level of radiation associated with them. NORM typically has a lower level of radiation than TENORM, which can have higher levels of radiation as a result of the concentration of radioactive materials through human activities. However, it’s important to note that the level of radiation can vary depending on the specific materials and the location.
To safely manage NORM and TENORM, it’s important to first identify and assess potential sources of exposure. This includes conducting regular radiation surveys and monitoring the environment to determine the levels of radiation present. Once potential sources of exposure have been identified, it’s important to implement controls to minimize exposure, such as using personal protective equipment (PPE) and implementing strict protocols for handling and disposing of the materials.
Another important aspect of managing NORM and TENORM is separating the materials from other waste streams. This can be done by using various methods such as gravity separation, density separation, or magnetism separation. It’s also important to ensure that the materials are properly stored and labeled to prevent accidental exposure.
One of the key challenges in managing NORM and TENORM is the permissible dose of radiation that a worker can be exposed to. The International Atomic Energy Agency (IAEA) sets the standard for the permissible dose of radiation for workers in the field of gas and oil. According to the IAEA, the maximum annual radiation dose for workers in this industry should not exceed 20 millisieverts (mSv).
To reduce the exposure of workers to NORM and TENORM, employers should take necessary steps to minimize the worker’s exposure as much as possible. This includes providing workers with personal protective equipment (PPE) such as radiation-shielding clothing and dosimeters, implementing strict protocols for handling and disposing of radioactive materials, and regularly monitoring the environment for any leakage or spills.
It’s important to consider the option of reusing NORM and TENORM. These materials can be processed and reused in various industries such as construction, ceramics, and fertilizers. However, it’s important to ensure that the materials are properly processed and the level of radiation is within the permissible limit before reuse.
Managing NORM and TENORM is a critical aspect of the oil and gas industry. By identifying and assessing potential sources of exposure, implementing controls to minimize exposure, and properly managing and disposing of these materials, companies can work to ensure that workers are protected and that radiation levels are within acceptable limits. It is also important to comply with all relevant federal and state regulations regarding radiation safety and to keep in mind that radiation exposure is cumulative over a lifetime.
One of the best ways to minimize exposure to radiation is to properly train workers on the hazards of radiation and how to protect themselves. This includes providing workers with personal protective equipment (PPE) such as radiation-shielding clothing and dosimeters and implementing strict protocols for handling and disposing of radioactive materials. Companies should also regularly monitor the environment and conduct radiation surveys to ensure that radiation levels are within safe limits.
Another important aspect of managing NORM and TENORM is to consider the option of reusing these materials. This can be done by processing and purifying them before reuse, and ensuring that the level of radiation is within the permissible limit.
In short, radiation safety is a critical aspect of the oil and gas industry and companies need to understand the unique hazards associated with NORM and TENORM, take the necessary precautions to minimize exposure, and properly manage and dispose of these materials. It is a shared responsibility among all parties involved to manage and minimize the risk associated with radiation, both for the workers and the surrounding community.
In conclusion, NORM and TENORM are naturally occurring radioactive materials that can be found in the oil and gas industry. Understanding the differences between NORM and TENORM, identifying potential sources of exposure, implementing controls to minimize exposure, and properly managing and disposing of these materials are all crucial to ensuring the safety of workers and the public. It is also important to comply with all relevant federal and state regulations regarding radiation safety, including obtaining the necessary licenses and permits, as well as regularly reporting radiation levels and other safety information to the appropriate regulatory agencies. Additionally, it’s important to keep in mind that radiation exposure is cumulative over a lifetime, so it is crucial to minimize the worker’s exposure as much as possible to protect their health and safety over time. It is important to remember that radiation safety is a shared responsibility among all parties involved and it is crucial to work together to minimize the risk associated with radiation, both for the workers and the surrounding community. By implementing proper radiation safety measures, companies can help to ensure that their operations are not harming the environment and that the public is not being exposed to excessive radiation levels.
