As creatures consume carbon from their environment and incorporate it into their bodies, they consume both carbon-12 and carbon-14.When a creature dies, it ceases to consume more carbon.If either assumption is wrong carbon-14 dating doesn't work.The first assumption is fairly reasonable, though some scientists have recently called into question whether or not nuclear decay rates were accelerated in the past (this might change the rate of carbon-14 decay). Radiocarbon dating is the technique upon which chronologies of the late Pleistocene and Holocene have been built.This resource is designed to provide online information concerning the radiocarbon dating method.


Once an organism is dead, however, no new carbon is actively absorbed by its tissues, and its carbon 14 gradually decays.

The second assumption isn't as reasonable seeing as we know that the carbon-12 to carbon-14 ratio changes.

Scientists have tried to minimize the uncertainties by using other dating techniques like dendrochronology (tree-ring dating) but their success is questionable and carbon-14 dating remains a controversial dating technique. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him.

When these neutrons collide with nitrogen-14 in the atmosphere, carbon-14 can be created Iodine-131 is used to destroy thyroid tissue in the treatment of an overactive thyroid. If a hospital receives a shipment of 200 g of iodine-131, how much I-131 would remain after 32 days?
