For instance, iodine-131 has a half life of 8 days which is long enough for it to concentrate in the thyroid gland, allowing doctors long enough to monitor its function, but not so long as to cause damage.Iodine-131 is one of the most widely used isotopes.The original atom is referred to as the parent and the following decay products are referred to as the daughter.For example: after the it forms a component of all organic compounds and is therefore fundamental to life. Libby of the University of Chicago predicted the existence of carbon-14 before it was actually detected and formulated a hypothesis that radiocarbon might exist in living matter.Shortly after Becquerel's find, Marie Curie, a French chemist, isolated another highly radioactive element, .
However, no geologists were present when the earth and its many rock layers were formed, so they cannot know where the radiometric clocks were set at the beginning.
Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline.
Mike Riddle exposes the unbiblical assumptions used in these calculations The primary dating method scientists use for determining the age of the earth is radioisotope dating.
It is supplied in capsules or liquid of a specific activity designed to be swallowed by patients.
Iodine is a naturally occurring element known as Iodide.
