The rate of decay is often referred to as the activity of the isotope and is often measured in Curies (Ci), one curie = 3.700 x 10" is the initial amount of radioisotope at the beginning of the period, and "k" is the rate constant for the radioisotope being studied.In this equation, the units of measure for N and No can be in grams, atoms, or moles.(Since this is a decay problem, I expect the constant to be negative.

We can apply our knowledge of first order kinetics to radioactive decay to determine rate constants, original and remaining amounts of radioisotopes, half-lives of the radioisotopes, and apply this knowledge to the dating of archeological artifacts through a process known as carbon-14 dating., where r is a measurement of the rate of decay, k is the first order rate constant for the isotope, and N is the amount of radioisotope at the moment when the rate is measured.The task requires the student to use logarithms to solve an exponential equation in the realistic context of carbon dating, important in archaeology and geology, among other places.Students should be guided to recognize the use of the logarithm when the exponential function has the given base of \$e\$, as in this problem.The ratio of "N/N Carbon-14 is a radioisotope formed in our atmosphere by the bombardment of nitrogen-14 by cosmic rays.

The amount of carbon-14 in the atomosphere is, on an average, relatively constant.

(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.

Carbon 14 is a common form of carbon which decays over time.

The amount of Carbon 14 contained in a preserved plant is modeled by the equation \$\$ f(t) = 10e^.

The half-life of carbon-14 is approximately 5,730 years, and it can be reliably used to measure dates up to around 50,000 years ago.
