Which of the following radioisotopes is used as anticancerous?
\(\mathrm{Na}-24\)
\(\mathrm{C}-14\)
\(\mathrm{U}-235\)
\(\mathrm{Co}-60\).
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.
