One excellent example of this is the use of carbon-14 to determine the steps involved in photosynthesis in plants.We know these steps because researchers followed the progress of carbon-14 throughout the process.Many people still cling to a different notion, despite the scientific evidence.The radiation emitted by some radioactive substances can be used to kill microorganisms on a variety of foodstuffs, extending the shelf life of these products.A tiny amount of carbon-14 is produced naturally in the upper reaches of the atmosphere, and living things incorporate some of it into their tissues, building up to a constant, albeit very low, level.Once a living thing dies, it no longer acquires carbon-14; as time passes the carbon-14 that was in the tissues decays.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.The amount of radioactive iodine that collects there is directly related to the activity of the thyroid, allowing trained physicians to diagnose both hyperthyroidism and hypothyroidism.

After incorporating radioactive atoms into reactant molecules, scientists can track where the atoms go by following their radioactivity.Produce such as tomatoes, mushrooms, sprouts, and berries are irradiated with the emissions from cobalt-60 or cesium-137.
