C) Positron Emission
D)

Cobalt-59 is a stable isotope. Cobalt-60 is used as a radioactive source approved by the U.S. Food and Drug Administration for irradiation of food. This process kills microbes and insects and can delay ripening. What decay pathway is likely for cobalt-60?

A) ( $\alpha$ emission)
B) ( $\beta$ emission)
C) positron emission
D) ( $\gamma$ emission)
E) X-ray emission
