Radiometric Dating

  1. Feb 21, 2008 #1
    Hi guys, this is one of the questions on an internal assessment that i have to do. it talked about carbon-14 and how it has a half-life of 5730 yrs. "In a sample of bone discovered in a Neolithic grave, the amount of radioactive C-14 was found to be only 1% of that in living things. How old was the bone?" I really don't know where to start, I mean...how do we know how much are in living things? Doesn't it vary from one to another?
    Please help me as soon as you get a chance. I'm in a bit of a hurry. Thanx!

    Although it's widely accepted as accurate, there are some who argue the assumptions behind carbon dating. Regardless, you're expected to assume that the sample initially had the same concentration of carbon 14 as currently living creatures do.
