Question

In treatment of cancer, which of the following is used?

• A. ${}_{53}{}^{131}\mathrm{I}$
• B. ${}_{15}{}^{32}\mathrm{P}$
• C. ${}_{27}{}^{60}\mathrm{Co}$
• D. ${}_1{}^2\mathrm{H}$

Answer 1

The correct option is C

${}_{27}{}^{60}\mathrm{Co}$

A nuclear reaction is used in the treatment of cancer. When a boron particle hits a neutron beam or gamma rays, it targets and kills cancer cells.

So, cobalt therapy is used for the treatment of cancer cells because it produces gamma rays.

Final answer:

Hence, option (C) is the correct answer.
