Question 16

Which row in the table is correct for alpha (α\alphaα), beta-minus (β−\beta^-β−), and gamma (γ\gammaγ) radiation?

A

Deflected by a magnetic field? (alpha: yes, beta-minus: yes, gamma: yes)

B

Typical range in air (alpha: a few cm, beta-minus: a few m, gamma: virtually infinite)

C

Electric charge (in units of eee) (alpha: +1+1+1, beta-minus: −1-1−1, gamma: 000)

D

Relative ionizing ability (alpha: lowest, beta-minus: medium, gamma: highest)
