Question

Different isotopes are matched with their uses as (i) Co- 60- To treat cancer (ii) U- 238- To produce electricity (iii) I-131- To treat goitre (iv) Na- 24- In agricultural research Which of the below matches are correct? (i) and (ii) (ii) and (iii) (iii) and (iv) (i) and (iii)

Answer 1

I-131- To treat goitre

U- 238- To produce electricity

(ii) (ii) and (iii)

Step-by-step explanation:

Radioisotopes have various applications in science. These applications may be positive or negative.

I-131- is used to treat goitre. This is a very important medical application of this isotope of iodine.

U-238 is ordinarily non-fissile but can be transformed to Pu-239 and used as a nuclear fuel for electricity generation.
