Alpha Decay

A radioactive sample decays through two different decay processes alpha -decay and beta -decay. Half-life time for alpha −decay is 3h and half-life time for beta −decay is 6h . What will be the ratio of number of initial radioactive to the number of nuclei present after 6 h ?.

A radioactive nucleus can decay be either emitting an alpha particle or by emitting a beta particle. Probability of alpha decay is 75% while that of beta decay is 25% the decayconstatnt of alpha decay is lamda_(1) and that of beta decay is lamda_(2) is (lamda_(1))/(lamda_(2))

If ._(92)U^(238) changes to ._(85)At^(210) by a series of alpha -and beta -decays, the number of alpha and beta -decays undergone is .

If ._(92)U^(238) changes to ._(85)At^(210) by a series of alpha -and beta -decays, the number of alpha and beta -decays undergone is .
