Question: What is radiometric method?

The radiometric, or gamma-ray spectrometric method is a geophysical process used to estimate concentrations of the radioelements: potassium, uranium and thorium in the near surface. This is done by measuring the gamma-rays which the radioactive isotopes of these elements emit during radioactive decay.

What is the radioactive clock method?

Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks. It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

What are 4 uses of radioactive isotopes?

Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies. Used to locate leaks in industrial pipe lines…and in oil well studies. Used in nuclear medicine for nuclear cardiology and tumor detection. Used to study bone formation and metabolism.

How is isotopes used in medicine?

Nuclear medicine uses radioactive isotopes in a variety of ways. One of the more common uses is as a tracer in which a radioisotope, such as technetium-99m, is taken orally or is injected or is inhaled into the body. Therapeutic applications of radioisotopes typically are intended to destroy the targeted cells.
