It has not been determined how the image was placed on the material.
(credit: Butko, Wikimedia Commons) Calculate the age of the Shroud of Turin given that the amount of found in it is 92% of that in living tissue.
Thus, if you know the number of carbon nuclei in an object (perhaps determined by mass and Avogadro’s number), you multiply that number by to find the number of nuclei in the object.
When an organism dies, carbon exchange with the environment ceases, and is not replenished as it decays.
Strategy Knowing that 92% of the remains means that . We also know that the half-life of is 5730 y, and so once is known, we can use the equation to find and then find as requested.
Here, we postulate that the decrease in is solely due to nuclear decay.
In this section we explore half-life and activity, the quantitative terms for lifetime and rate of decay. Half of the remaining nuclei decay in the next half-life.
The values obtained at the three independent laboratories gave a weighted average date of a.d. The uncertainty is typical of carbon-14 dating and is due to the small amount of in living tissues, the amount of material available, and experimental uncertainties (reduced by having three independent measurements).
This means they have shorter lifetimes, producing a greater rate of decay.
For example, radium and polonium, discovered by the Curies, decay faster than uranium.
Its remarkable negative imprint of an apparently crucified body resembles the then-accepted image of Jesus, and so the shroud was never disregarded completely and remained controversial over the centuries.
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.
