Text solutionVerified

Because of large mass and large velocity,

α

-particles have large ionising power. Each

α

-particle
produces thousands of ions before being absorbed. The

β

-particles ionise the gas through which
they pass, but their ionising power is only

\frac{1}{100}

th that of

α

-particles.

γ

-rays have got small ionising power.
Because of large mass, the penetrating power of

α

-particles is very small, it being

1/100

times that to

β

-rays
and

1/10000

times that of

γ

-rays.

α

-particles can be easily stopped by an Aluminium sheet, only

0.02 mm

thick.

β

-particles have very small mass, so their penetrating power is large.

γ

-rays have very large penetrating power.
