RADIOACTIVE DECAY & HALF LIFE TIME

Half-life of a radioactive substance A is 4 days. Find the probability that a nucleus will decay in two half- life

Life time || Half Life time || Average Life time OF a Radioactive Sample || Units OF Radioactivity (Baeyer,Curie,Ratherford)

Radioactive nucleus A decays into B with half-life 10sec . A also convert into C with half-life 100 sec . Find half-life of A for both emission.

Radioactive nucleus A decays into B with half-life 10sec . A also convert into C with half-life 100 sec . Find half-life of A for both emission.

Assertion In one half-life of a radioactive substance more number of nuclei are decayed than in one average life. Reason Average life = Half -life/in (2)

Assertion In one half-life of a radioactive substance more number of nuclei are decayed than in one average life. Reason Average life = Half -life/in (2)

The half - life period of radioactive element A is the same as the mean life time of another radioactive element B. Initially both of them have same number of atoms. The radioactive element B decays faster than A. Explain, why.

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 ?.
