We know that we use carbon-14 for radiometric dating of any fossil or old substance containing carbon

. The choice of Carbon-14 for dating purpose is due to its radioactive nature

So after a certain time period the amount of C-14 decreases from a body after death and by measuring the amount of Carbon 14 remained in a body we can assess the age of that particular body

A living organism continuously exchange Carbon -14 from atmosphere and this stops after death.

Carbon-14.

Further explanation

  • Living things like animals and plants have a known proportion of carbon-14 in their tissues. Carbon-14 is one of the radioisotopes of carbon.
  • When they die, they stop taking carbon in, then the amount of carbon-14 decreases at a known rate.  
  • The age of ancient organic materials can be obtained by measuring the amount of carbon-14 that remains. This activity is what we call radioactive dating.
  • Carbon-14 has a half-life of 5,700 years.

It can be concluded that the element of carbon-14 is most important to scientists doing radiometric dating.

Uses of radioactivity

  • Radiography. A picture can be obtained on film with the help of radioactivity emissions. This is known in medicine as a roentgen film. X-rays are used which are produced by electronic devices.
  • Sterilizing. Gamma rays can be used to kill bacteria, mold, and insects in food even after it has been packaged.
  • PET or Positron Emission Tomography is a technique that uses an isotope of carbon, especially carbon-11, as the radioactive tracer to measure the changes in blood flow within the brain.
  • Radioactive tracers. The most common tracer is technetium-99 and is very safe because it only emits gamma rays and doesn't cause much ionization. A small amount of iodine-123 can be used for medical checkings, like checking for a blocked kidney.
  • Radiotherapy as a treatment for cancerous and tumors. Tracers like cobalt-60, technetium-99, iodine-131, and phosphor-32 are used to detect, locate, and diagnose tumors and treat cancers.
