Problem

A nuclide

A

undergoes

\alpha

-decay and another nuclide undergoes

\beta

-decay, then: (1) The

\alpha

-particles emitted by

A

may have widely different speed (2) All the

\beta

-particles emitted by

B

will have same speed (3) The

\beta

-particles emitted by

B

have widely different speeds (4) In both cases

\alpha

- and

\beta

- have almost same speed.
