100g of radium was placed at a table with half life of 5 years. After 25 years what would be the amount of Radium left?

Calculate the disintegration constant of Cobalt 60 if its half-life to produce Nickel – 60 is 5.2 year.

The half-life period of radon is 3.825 days. Calculate the decay constant of radon.

The statistical average of the lives of all atoms present at any time is called as Average life.

The average life of radium is 2400 years.

Its decay constant and half life respectively are
