Newmont's mission is to build a sustainable mining business while leading in safety, environmental stewardship and social responsibility. Today, we primarily mine gold and copper, as well as silver and other metals and minerals.
In addition to yellowcake, uranium recovery operations generate waste products, called byproduct materials, that contain low levels of radioactivity. For mining activities, the regulatory responsibility depends on the extraction method that the given facility uses.
Mining & petroleum companies use isotopes to locate and quantify geological mineral deposits Industrial Uses Oil gas & mining companies useand how much to apply to crops for maximum yield Isotopes help farmers and scientists control pests; e.g., California has used radiation sterilization since...
The Radiation Protection activities introduce students to the history of radiation protection, the concepts and devices used in radiation protection, careers in radiation protection, emergency planning and response, and laws that protect us.
TENORM: Copper Mining and Production Wastes Within the United States, mining and production of copper are primarily located in the West, specifically Arizona, New Mexico, Utah, Nevada and Montana. According to the United States Geological Survey (USGS), production in these states and Michigan account for more than 99% of domestic copper production.
The process used to increase the amount of uranium-235 relative to uranium-238 is known as uranium enrichment. U.S. civilian power plants typically use 3 to 5 percent uranium-235. Weapons use "highly enriched uranium" (HEU) with over 90 percent uranium-235.
This is the second of two reports on uranium mining TENORM. This report investigates the potential radiogenic cancer risks from abandoned uranium mines and evaluates which may pose the greatest hazards to members of the public and to the environment.
Coal Ash Is More Radioactive Than Nuclear Waste By burning away all the pesky carbon and other impurities, coal power plants produce heaps of radiation By Mara Hvistendahl on December 13, 2007
radiation measuring instruments for mining. The radiation measuring instruments commonly used in industrial radiography are described in more detail in the equipment that measuring radiation in mining.
The exact source of the radiation is unclear, and it may originate from the ore concentrates, or the natural gas used in the smelter, or it may come from some other source. Copper mining waste piles may be as large as 400 hectares and typically include three types of waste:
Nuclear gauges are also used for industrial, mining, and scientific purposes. In USDA, nuclear gauges are used for building roads and dams, and for collecting scientific data on soil water content in agricultural and forestry settings.
Uranium is a natural mineral and has been mined and used for its chemical properties for thousands of years. The U.S. mining industry can retrieve uranium in two ways: by mining rock that contains uranium or by using strong chemicals to dissolve uranium from the rock that is still in the ground.
Radioactive Waste and Uranium Mines Radioactive Waste and Uranium Mines Description. Radioactive Materials and Wastes covers materials from a wide range of sources that emit radiation of different types, at levels that impact human health. Radioactive materials are used for power generation, military purposes, for treatment and analyses in the ...

Mining is a good example of an activity resulting in exposure to TENORM. We use a variety of tools to bring rocks and soils that were previously inaccessible out of the mines, take from them the minerals we want, and treat the rest as radioactive waste.

to uranium mining and the use of uranium to produce nuclear power. Because of this concern, national and international agencies have been set up to research and regulate activities that are related to radiation exposure
Radioisotopes in Industry, use of radioisotopes for radiography, gauging applications and mineral analysis. Short-lived radioactive material used in flow tracing and mixing measurements. Gamma sterilisation is used for medical supplies, some bulk commodities and, increasingly, for food preservation.
Uranium mining operations; Radiation pollution can cause birth defects, cancer, sterilization, and other health problems for human and wildlife populations. Pollution : POLLUTION Sep 28, 2010 · Heaps of mining waste are left behind and these waste often contain several poisonous ...
Radiation is energy that travels through vacuums, air and some material and is part of the natural environment. Includes cosmic rays from outer space, gamma radiation from uranium, thorium, and potassium in the ground, radon gas in the air, and radioactive elements in our food and water. Non ...
Uranium Mining In the last fifty years uranium has become one of the world's most important energy minerals. It is used almost entirely for making electricity, though a small proportion is used for the important task of producing medical isotopes.

The Florida Department of Environmental Protection put together a technical advisory team that looked at the situation and came up with recommendations that resulted in new regulations for earthen dams used in phosphate mining.
The Radiation Exposure Compensation Act (RECA) provides one-time benefit payments to persons who may have developed cancer or other specified diseases after being exposed to radiation from atomic weapons testing or uranium mining, milling, or transporting.
Advances in mining technology and safety monitoring makes many of the radiation/health issues associated with previous mining unlikely. These include better ventilation systems, possible robotic mining, and monitoring badges to make sure workers do not exceed the allowable radiation dosages.
Although scientists have only known about radiation since the 1890s, they have developed a wide variety of uses for this natural force. Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity.
Uranium Mining and Mill Tailings. Uranium mining and mill tailings are pulverized rock and soils that remain after mining for uranium. The radionuclides present usually include uranium, radium, radon, and …
Mining stone for countertops may unearth some potentially scary radioactivity as well. Granite countertops are known to emit radiation and radon, albeit at very low levels, as they can contain naturally occurring uranium and other radioactive elements, such as thorium.
