That’s because some cells are born after you are, sometimes many many years after, but we’re not really sure which ones, or when — it’s not as if there are cellular birthday parties, marked by balloons and cake.

So the question of age remained relatively unanswered until the early aughts, when scientist While Mary Webster has a very interesting analysis of tissue age, she is apparently unaware of the natural production of C-14 by cosmic rays in the upper atmosphere.

Organisms at the base of the food chain that photosynthesize – for example, plants and algae – use the carbon in Earth’s atmosphere.

They have the same ratio of carbon-14 to carbon-12 as the atmosphere, and this same ratio is then carried up the food chain all the way to apex predators, like sharks.

Atomic testing that took place in the upper atmosphere has nothing to do with normal C-14 production.

I'm surprised that she hasn't heard of "carbon dating" that is done by measuring the beta emission from all organic material discovered by Willard Libby in 1949. Mary can apologize for not knowing that atomic atmospheric testing is not necessary for her work. I think that we need to gather more evidence about the nuclear testing that may have happened there. We need to explore.having reached the level of a 3rd grade science education (at the age of 60) i really enjoyed the poem to magnesium.

To understand radiocarbon dating, you first have to understand the word Although an element’s number of protons cannot change, the number of neutrons can vary slightly from each atom.

Once the radiocarbon atom is produced, it rapidly combines with oxygen (OC (7 neutrons) atoms.
