# Carbon dating exponential decay

If I end up with a positive value, I'll know that I should go back and check my work.) In Its radiation is extremely low-energy, so the chance of mutation is very low.(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.

Clearly, population growth depended on this since the number of people that can be born in a year depends on the number of people able to bear children during that year.How am I supposed to figure out what the decay constant is?I can do this by working from the definition of "half-life": in the given amount of time (in this case, hours.the chance that an atom will decay in the next second is unaffected by the fact that it did not decay a second ago.Clearly the number of atoms decaying in one second depends on the number of atoms you start with, but the chance of any individual atom decaying in a given time period is always the same.Return the remaining heads up pennies to the box and toss them again onto the table surface.

Remove the tails up pennies and stack them into a second column right beside the first column.

That's exactly the model we need for radioactive decay since the chance of any particular atom decaying in one second is unaffected by the fact that it did not decay a second ago.

The lab procedure to mimic radioactive decay is simple. Toss the pennies onto a table surface or the floor.

I do not have the decay constant but, by using the half-life information, I can find it.

(Since this is a decay problem, I expect the constant to be negative.

Repeat the process until all pennies have landed tails up.
