Question

two uses of isotopes
(I) An isotope of Uranium is used as a fuel in nuclear reactors

(II) An isotope of Cobalt is used in the treatment of cancer
​

Answer 1

Answer:

Uranium-235 (U-235) is only found in about 0.7 percent of uranium found naturally, but it is well-suited for producing nuclear power. This is because it decays naturally by a process known as alpha radiation. This means that it releases an alpha particle (two neutrons and two protons connected together).

Thus isotope of Uranium U-235 is suitable as a fuel for nuclear reactor

B. Co

(

60) isotope is used in the treatment of cancer.

C. The exceptionally useful radioactive isotope is iodine-131, which has a half-life of eight days. It is employed in medicine to monitor thyroid gland functioning, to treat goiter and thyroid cancer.

Thus, all given options are correct
