19 explain carbon 14 radioactive dating
We know these steps because researchers followed the progress of carbon-14 throughout the process.
Radioactive isotopes are useful for establishing the ages of various objects.
Eggs and some meat, such as beef, pork, and poultry, can also be irradiated.
Using such methods, scientists determined that the age of the Shroud of Turin (Figure 15.3 "Shroud of Turin"; purported by some to be the burial cloth of Jesus Christ and composed of flax fibers, a type of plant) is about 600–700 y, not 2,000 y as claimed by some.
