Composite wireline log for the Lisburne 1 well, Alaska - the neutron and density logs used radioactive sources. Sealed radioactive sources are routinely used in formation evaluation of both hydraulically fractured and non-fracked wells. The sources are lowered into the borehole as part of the well logging tools, and are removed from the ...
A radioactive source is a known quantity of a radionuclide which emits ionizing radiation, typically one or more of the radiation types gamma rays, alpha particles, beta particles, and neutron radiation. Sources can be used for irradiation, where the radiation performs a significant ionising function on a target material, or as a radiation ...
Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products 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.

A Florida company kept a dangerous secret from the public for three weeks: A massive sinkhole had leaked at least 215 million gallons of radioactive water into an aquifer.
A major radioactive contamination threat to the Columbia River should be removed at the Hanford nuclear site before the end of summer. Hanford workers have started to pump contaminated water from ...
Massachusetts environmental regulators have denied a request by the company dismantling a shuttered nuclear power plant to release more than 1 million gallons (3.8 million liters) of radioactive ...
The radioactivity from these sources exceeded legal limits. [5] [6] Since then, contaminated water has been pumped into storage units and gradually treated using the Advanced Liquid Processing System (ALPS) to eliminate most radionuclides, [3] [7] except notably tritium with a half-life of 12.32 years.
Radionuclide therapy (RNT, also known as unsealed source radiotherapy or molecular radiotherapy) uses radioactive substances called radiopharmaceuticals to treat medical conditions, particularly cancer.
