Which of the following radioisotopes is used as anticancerous?

A
\(\mathrm{Na}-24\)
B
\(\mathrm{C}-14\)
C
\(\mathrm{U}-235\)
Correct answer
D
\(\mathrm{Co}-60\).

Solution

Radiation ( \(\gamma\)-rays) emitted by the radioactive substances \(\left({ }_{27} \mathrm{Co}^{60}\right)\) destroys the cells. Hence, it is used in treatment of cancer in which the malignant cells are wiped out.

Hence, the correct answer is option: 'D'.
