The most common use of these radiotracers is at the well head for the measurement of flow rate for various purposes. A 1995 study found that radioactive tracers were used in over 15% of stimulated oil and gas wells. [2] Use of these radioactive tracers is strictly controlled.
To obtain individual well flow rates, it is common to use a smaller test separator. This is an isolated and down-scaled processing system in parallel with the normal flows. Regularly, for example once a month per well, the flow from one and only one selected well is led into the test separator for determining well flow rate for the selected ...
This is a list of Superfund sites in Indiana designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

A well counter is a device used for measuring radioactivity in small samples. It usually employs a sodium iodide crystal detector . It was invented in 1951 by Hal Anger , who is also well known for inventing the scintillation camera . [ 1 ]
IAEA officials say Fukushima's ongoing discharge of treated radioactive wastewater is going well. MARI YAMAGUCHI. October 23, 2023 at 10:43 AM. TOKYO (AP) ...
Hydraulic fracturing is the propagation of fractures in a rock layer by pressurized fluid. Induced hydraulic fracturing or hydrofracking, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction, particularly from unconventional reservoirs.

The People's Republic of China conducted CHIC-4 with a Dongfeng-2 rocket launch on October 25, 1966. The warhead exploded with a yield of 12 kt.
Indiana lawmakers want to track down registered voters who might not be citizens. But that process has been challenged in other states. Indiana wants to weed out non-citizens from voter rolls.
