Uses of Isotopes

Isotopes: Isotopes are the atoms of same element with same proton number but different proton number. Radioactive isotopes are the isotopes of radioactive element. Thus Radioactive or radioisotopes are used to understand the mechanism of different reactions. Such as C 14 which is radioactive isotope of carbon is used to label CO2 i-e how CO2 can be used to form glucose through photosynthesis.

Archaeological or Geological:Radioactive or radioisotopes are used to estimate the age of fossils. It is based on the half-lives of radioactive isotopes and is called radioactive isotope dating. Such as radiocarbon dating is used to determine the age of old carbon containing material.

Treatment of cancer:Radioactive or radioisotopes are used to treat cancer because it can produce radioactive rays to kill cancerous cells. This process is called radiotherapy. Such as radio isotopes 9 32 and Sr 90 are used to treat skin cancer because it is less penetrating beta radiation.

As tracer in medicines:Radioactive or radioisotopes are used as tracer in medicines to diagnose different diseases. Such as TC technetium is used to monitor the bones growth.


In Power Generation:Radioactive or radioisotopes produces rays if these rays are controlled carefully then we can run or drive turbine through Radioactive or radioisotopes rays to generate electricity. In Pakistan Kanupp (Karachi), Nilore (Islamabad) and Chashma nuclear energy center produces electricity based on this method.
