Radioactive dating problems and answers
Its remarkable negative imprint of an apparently crucified body resembles the then-accepted image of Jesus.
Another way of considering the decay constant is that a given carbon-11 nuclei has a 0.0568 percent probability of decaying each second.
The decay of carbon-11 allows it to be used in positron emission topography (PET) scans; however, its 20.334 min half-life does pose challenges for its administration.
(b) One hour is nearly three full half-lives of the carbon-11 nucleus.
As a result, one would expect the amount of sample remaining to be approximately one eighth of the original amount.
