So, objects older than that do not contain enough of the isotope to be dated.Conversely, the method doesn't work on objects that are too young.what range of C^14 to C^12 ratio would the scientist expect to find in the animal remains?Im not really sure how to go about solving this problem, any help would be apprecaited. Libby and others (University of Chicago) devised a method of estimating the age of organic material based on the decay rate of the quantity of radioactive material at time zero, X is the amount remaining after time t, and k is the first order rate constant, which is a characteristic of the isotope undergoing decay.The two solutions provided differ slightly in their approach in this regard.If you're seeing this message, it means we're having trouble loading external resources on our website.

So, if you were asked to find out carbon's half-life value (the time it takes to decrease to half of its original size), you'd solve for t number of years when in any remains will have broken down.(Whatever you're being treated for is the greater danger.) The half-life is just long enough for the doctors to have time to take their pictures.The dose I was given is -younger copy of an earlier document (in which case it is odd that there are no references to it in other documents, since only famous works tended to be copied), or, which is more likely, this is a recent forgery written on a not-quite-old-enough ancient parchment.The exponential decay formula is given by: $$m(t) = m_0 e^$$ where $\displaystyle r = \frac$, $h$ = half-life of Carbon-14 = 30$ years, $m_0$ is of the initial mass of the radioactive substance.So, we have: $\displaystyle r = \frac = \frac = 0.000121$ The mass ratio of Carbon-14 to Carbon-12 is $\displaystyle m_0 = \frac$ (just look this up).
