Carbon dating decay

All three laboratories found samples of the shroud contain 92 percent of the Part of the Shroud of Turin, which shows a remarkable negative imprint likeness of Jesus complete with evidence of crucifixion wounds.

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.

If an individual nucleus survives through that time, it still has a 50 percent chance of surviving through another half-life.

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.

The time in which half of the original number of nuclei decay is defined as the .

One of the most famous cases of carbon-14 dating involves the Shroud of Turin, a long piece of fabric purported to be the burial shroud of Jesus (see Figure 22.28).

This relic was first displayed in Turin in 1354 and was denounced as a fraud at that time by a French bishop.

Half of what remains decays in the next half-life, and half of that in the next, and so on.
