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.

That means they have shorter lifetimes, producing a greater rate of decay.

For example, radium and polonium, discovered by Marie and Pierre Curie, decay faster than uranium.

As a result, one would expect the amount of sample remaining to be approximately one eighth of the original amount.

The 129.4 g remaining is just a bit larger than one-eighth, which is sensible given a half-life of just over 20 min.(c) Label analysis shows that the unit of Becquerel is sensible, as there are 0.0735 g of carbon-11 decaying each second.

Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

This activity was selected for the On the Cutting Edge Exemplary Teaching Collection Resources in this top level collection a) must have scored Exemplary or Very Good in all five review categories, and must also rate as “Exemplary” in at least three of the five categories.

Carbon-14 dating was not performed on the shroud until 1988, when the process had been refined to the point where only a small amount of material needed to be destroyed.

Samples were tested at three independent laboratories, each being given four pieces of cloth, with only one unidentified piece from the shroud, to avoid prejudice.

Therefore, the number of radioactive nuclei decreases from A more precise definition of half-life is that each nucleus has a 50 percent chance of surviving for a time equal to one half-life.
