TENORM: Uranium Mining Residuals Radiation Protection

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

What is radiation therapy and how is it used?

Radiation Therapy Techniques. Radiation can damage normal cells. It is important that the radiation be targeted to the cancer. An advanced form of threedimensional (3D) conformal radiation, called intensity modulated radiation therapy, or IMRT, more precisely conforms the dose to the tumors, allowing safer delivery of higher doses of radiation.. Other techniques that enable ultraprecise

Medical Uses for Radiation

Medical Uses. There are many uses of radiation in medicine. The most well known is using x rays to see whether bones are broken. The broad area of xray use is called radiology. Within radiology, we find more specialized areas like mammography, computerized tomography (CT), and nuclear medicine (the specialty where radioactive material is usually injected into the patient).

Medical imaging Wikipedia

In the case of projectional radiography, the probe uses Xray radiation, which is absorbed at different rates by different tissue types such as bone, muscle, and fat. The term "noninvasive" is used to denote a procedure where no instrument is introduced into a patient''s body, which is the case for most imaging techniques used.

Uranium Mining Overview World Nuclear Association

Generally speaking, uranium mining is no different from other kinds of mining unless the ore is very high grade. In this case special mining techniques such as dust suppression, and in extreme cases remote handling techniques, are employed to limit worker radiation exposure and to ensure the safety of the environment and general public.
