Material giving rise to these enhanced exposures has become known as naturally occurring radioactive material (NORM). Historically, most regulatory attention has been focused on the mining and processing of uranium ore, because such activities are a direct consequence of the radioactivity in the ore and form part of the nuclear fuel cycle.
Naturally Occurring Radioactive Materials (NORM)and Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) consist of materials, usually industrial wastes or byproducts enriched with radioactive elements found in the environment, such as uranium, thorium and potassium and any of their decay products, such as radium and radon.

Naturally occurring radioactive materials (NORM), including uranium ore or other mineral deposits containing radionuclides (such as some mineral sands, some rare earth minerals or gold/copper deposits) may pose a risk to workers'' health. Similar to any other hazard at a mine, this hazard and associated risks must be managed.
material (TENORM)) and (or) enhanced potential for exposure to naturally occurring radioactive materials in products, byproducts, residues and wastes. Such activities may include, for instance, the mining and processing of ores, the combustion of fossil fuels, or the production of natural gas and oil. If these residues containing naturally ...
NATURALLY OCCURRING RADIOACTIVE MATERIAL If you currently work in the Oil Gas or Mining industry, or are aspiring to, then it''s more than likely you will come across NORM. NORM IN MINING, OIL GAS. READ MORE. RADIATION MANAGEMENT PLANS (RMPs) COMPLIANCE AUDITS.
Naturallyoccurring radioactive material (NORM) is the term used to describe materials that contain radionuclides that exist in the natural environment. Longlived radioactive elements of interest include uranium, thorium and potassium, and any of their radioactive decay products, such as radium and radon.
mental Protection Agency data on technologically enhanced naturally occurring radioactive materials (TENORM) emanating from copper mines. EPA developed this report to provide a better understanding of the nature and extent of TENORM at copper mining and mineral processing sites.
Radiation Professionals consultants have extensive expertise identifying and quantifying NORM (Naturally Occurring Radioactive Material) contaminated sites and facilities in the mining industry. Support from our team includes: Site surveys to identify the .
Accumulation of mine wastes with high concentrations of potentially toxic elements has been occurring in different mining regions of Mexico. Few data are available on the activity concentration of natural radionuclides in metallic mine wastes. Radioactive data is necessary to assess the impact of mine wastes from a radiological point of view.

In this report, Naturally Occurring Radioactive Material (NORM) is defined as: Materials which may contain any of the primordial radionuclides or radioactive elements as they occur in nature, such as radium, uranium, thorium, potassium, and their radioactive decay products, that are undisturbed as a result of human activities.
uraniferous area. Copper mine wastewater may contain a number of alpha and beta emitters and routine control of the mine wastewater requires the measurement of mixtures of naturally occurring radionuclides. In 1993, a zero radioactivity limit value (no discharge accepted) for any radioactive material was adopted into
EPA has shown that copper mining in Arizona generates substantial radioactive waste, called TENORM (Technologically Enhanced Naturally Occurring Radioactive Materials), and TENORM from the Rosemont Mine has been cited as a major environmental concern.

Special Wastes Branch, Mining Waste Section MC 5302W, 401 M St., Washington, 20460. ABSTRACT The Environmental Protection Agency (EPA) has been working to better understand the nature and extent of naturally occurring radioactive materials (NORM) that may become concen trated at copper mining sites.
Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2015 amounted to 60,496 tonnes. Kazakhstan, Canada, and Australia are the top three producers and together account for 70% of world uranium production. Other important uranium producing countries in excess of 1,000 tons per year are Niger, Russia, Namibia, Uzbekistan, China, the ...
For mining and minerals processing, radioactivity and radioactive materials are always present, and appropriate management and regulation that is commensurate with the actual risk is important. This avoids overregulation due to perception. International approach to naturally occurring radioactive material
2 Managing naturally occurring radioactive material (NORM) in mining and mineral processing Guideline NORM 1 Applying the system of radiation protection to mining operations Practicable means reasonably practicable having regard, where the context permits, to:
Natural Occurring Radioactive Material. Oil and gas production mobilize naturally occurring radioactive material (NORM) from the deep underground reservoir rock. The radionuclides are primarily 226 Ra, 228 Ra and 210 Pb and appear in sludge and scales and in the produced water. Scales and sludge containing NORM represent an increasing amount of ...
Another situation is the mining and/or processing of material where the activity concentrations of radionuclides of natural origin in the material itself, or in any material arising from the process, are significantly elevated — such material ... Naturally occurring radioactive material (NORM) assessment of oil and gas production ...
Naturally Occurring Radioactive Material The naturally occurring radioactive elements uranium and thorium, like most chemical elements, are formed in stars and comprise a small amount of the material that formed the earth. The radioactive isotopes uranium238 (U238) and thorium232 (Th232) have decay times (halflives)
Mining mineral processing; NORM. NORM. Naturally occurring radioactive material (NORM) is the term used to describe materials containing radioactive materials that exist in the natural environment. NORM is widespread. Sands, clays, soils, rocks and many ores and minerals can contain varying amounts of naturally occurring radionuclides.
Material giving rise to these enhanced exposures has become known as naturally occurring radioactive material (NORM).
