Carbon-14, C-14, 14 C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.Its presence in organic matter is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.
The Waste Isolation Pilot Plant, or WIPP, in New Mexico, US, is the world's third deep geological repository (after Germany's Repository for radioactive waste Morsleben and the Schacht Asse II salt mine) licensed to store transuranic radioactive waste for 10,000 years.
Soon after the publication of Libby's 1949 paper in Science, universities around the world began establishing radiocarbon-dating laboratories, and by the end of the 1950s there were more than 20 active 14 C research laboratories. It quickly became apparent that the principles of radiocarbon dating were valid, despite certain discrepancies, the ...
In the early 2000s, the U.S. Department of Energy started funding work for research into capturing carbon on purpose, and New Mexico Tech secured $100 million in funding in 2002 for an ongoing ...
While the southeast portion of the county is in the Alamogordo district, that district contracts education of residents there to the Dell City Independent School District of Dell City, Texas, [3] due to the distances involved, as the mileage to Alamogordo from the former Cienega School was 100 miles (160 km) while the distance to Dell City is 20 miles (32 km).
This is a list of Superfund sites in New Mexico 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.

The next step, to correct for fractionation, can be done using either the 14 C / 12 C ratio or the 14 C / 13 C ratio, and also depends on which of the two possible standards was measured: HOxI or HoxII. R' std is then R' HOxI or R' HOxII, depending on which standard was used. The four possible equations are as follows. First, if the 14 C / 12
The bomb pulse is the sudden increase of carbon-14 (14 C) in Earth's atmosphere due to the hundreds of above-ground nuclear tests that started in 1945 and intensified after 1950 until 1963, when the Limited Test Ban Treaty was signed by the United States, the Soviet Union and the United Kingdom. [2]
