Radioisotopes :

Many elements have one or more isotopes that are unstable.These unstable isotopes decay emitting Alpha particles along with the gamma rays such isotopes are called as Radioisotopes.For Eg:.Tritium isotopes of hydrogen is radioactive.Similarly , C-14 is radioactive .These Radioisotopes find useful applications in various fields.

Applications of Radioisotopes :

• Cobalt-60 is used in the treatment of cancer.
• U-235 is used as fuel in nuclear reactors.
• P-32 isotope finds useful application in the field of agriculture.
• Radioactive Na-24 is used in the study of circulation of blood in the body.
• Radioactive I-131 isotope is used to check the working of thyroid gland and in the treatement of goitre.
