Radiometric dating lab
Radiocarbon dates do not tell archaeologists exactly how old an artifact is, but they can date the sample within a few hundred years of the age.
NGSS Guided Inquiry Explain about radiation and half-lives of isotopes.
It took months and sometimes years to obtain carbon dating results. Fastest AMS service worldwide: results in 3-14 business days BETA is able to offer rapid service because all analyses are done in-house.
The lab’s commitment to meet the scientific community’s demand for fast yet accurate carbon dating analysis led to immediate success. The lab has multiple accelerators with very high redundancy in spare parts ensuring that delivery times are met consistently.

Description: With the Half-Life Laboratory, students gain a better understanding of radioactive dating and half-lives.
Students use M&M’s (or pennies and puzzle pieces) to demonstrate the idea of radioactive decay.The rate of decay is a fixed rate called a half-life.The half-life of a radioactive isotope refers to the amount of time required for half of a quantity of a radioactive isotope to decay.It is a great introduction to the scientific process of deducing, forming scientific theories, and communicating with peers.It is also useful in the mathematics classroom by the process of graphing the data.The carbon-14 decays, with its half-life of 5,730 years, while the amount of carbon-12 remains constant in the sample.By looking at the ratio of carbon-12 to carbon-14 in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing.Carbon-14 has a half-life of 5730 years, which means that if you take one gram of carbon-14, half of it will decay in 5730 years. The ratio of the amounts of carbon-12 to carbon-14 in a human is the same as in every other living thing.After death, the carbon-14 decays and is not replaced.Based in Miami, Florida, the Beta Analytic radiocarbon dating lab revolutionized the fields of archaeology and late quaternary geology. (Universite de Paris Sorbonne) and Jerry Stipp, Ph. The company’s dedication to accuracy is at the core of its policies.Prior to the company’s inception in 1979, radiocarbon dates were scarce and available only through small university laboratories. By innovating new techniques, keeping abreast of the latest technology, and training qualified scientists to stay ahead of demand, Beta Analytic has maintained its firm commitment to quality over the years.
