Radioactive Half Life:

Radioactive Half Life:
The half-life of an Isotopes is the time it takes for ½ of the atoms to decay or disintegrate. Some isotopes decay rapidly ( Short half life) therefore they have a high specific activity.
Other isotopes decay slowly ( long half life) and have a low specific activity.
Every isotope has its own peculiar half – life ranging from microseconds to years.
Example: Cesium 137 has a half life of 30 years. Half life is ranging from microseconds to years.
Whether you started with 1 gram or 10 pounds at the end of 30 years, you would have ½ remaining. After 120 years 1/16 remaining.
