# There are two radioactive nuclei a and b one is alpha and one is beta emitter. Their disintegration constant are in the ratio of 1 :2 what should be the ratio of no of atom to A and B at any time t so that probability of getting Alpha and beta are same at that instant

Dear Brajesh

decay constant ratio = 1:2

so half life ratio = 2:1

so for getting probability of finding alpha and beta same ratio will be 1:2
