In a sample initially there are equal number of atoms of two radioactive isotopes A and B. 3 days later the number of atoms of A is twice that of B. Half life of B is 1.5 days. What is half life of isotope A? (in days)

Two radioactive substance X and Y initially contain equal number of nuclei. X has a half life of 1 hour and X has a half-life of 2 hours. After the ratio of activity of X to that of y is

The ratio of the atoms of two elements A and B at radioactive equilibrium is 5.0 xx 10^(5) : 1 respectively. Calculate half life of B if half life of A is 245 days.

A radioactive isotope X decays into a stable nucleus Y. Draw graphs showing the variation of rate of formation of Y versus time and the variation of population of Y versus time. Initial population of Y is zero.

In a graph of population, on x-axis time and on y-axis population is plotted. A parallel line to x-axis shows:
