Question: What isotope are they using to date the elephant deaths?

We use “bomb 14C” to determine ages of ivory from 14 different large seizures intercepted by law enforcement officials between 2002 and 2014. These ages represent the date of death of those elephants whose tusks were sampled.

What isotope is used to date things that have been alive?

Radiocarbon helps date ancient objects—but its not perfect. For nearly 70 years, archaeologists have been measuring carbon-14 levels to date sites and artifacts. Nothing good can last—and in the case of carbon-14, a radioactive isotope found in Earths atmosphere, thats great news for archaeologists.

How carbon-14 can help stop elephant poachers?

By measuring radioactive carbon-14 deposited in tusks and teeth following open-air nuclear bomb tests, the method reveals the year an animal died, and thus whether the ivory was taken illegally.

Botswana is home to a third of Africas declining elephant population. Officials say a total of 330 elephants are now known to have died from ingesting cyanobacteria.

How do you test for carbon 14?

There are three principal techniques used to measure carbon 14 content of any given sample— gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry. Gas proportional counting is a conventional radiometric dating technique that counts the beta particles emitted by a given sample.

How many elephants died in 2020?
