Application of isotopes in carbon dating

After incorporating radioactive atoms into reactant molecules, scientists can track where the atoms go by following their radioactivity.

One excellent example of this is the use of carbon-14 to determine the steps involved in photosynthesis in plants.

This exposure kills a lot of the bacteria that cause spoilage, so the produce stays fresh longer.

Eggs and some meat, such as beef, pork, and poultry, can also be irradiated.

To evaluate thyroid activity, a measured dose of I is administered to a patient, and the next day a scanner is used to measure the amount of radioactivity in the thyroid gland.Shroud of Turin In 1989, several groups of scientists used carbon-14 dating to demonstrate that the Shroud of Turin was only 600–700 y.Many people still cling to a different notion, despite the scientific evidence.Very little radioactive material is needed in these diagnostic techniques because the radiation emitted is so easy to detect.However, therapeutic applications usually require much larger doses because their purpose is to preferentially kill diseased tissues.
