Answer 1

The correct answer is A - II, B - I, C - IV, D - III, E - V.

Cobalt-60:
- It a radioactive isotope of cobalt used as a radiation source in many common industrial applications, such as in leveling devices and thickness gauges.
- It is used to treat cancer.
Potassium-40:
- It is a naturally occurring beta-emitting radioactive isotope of potassium.
- It is used for Geological Dating.
Iodine-131:
- It is a radioisotope of Iodine with a very short half-life of 8.02 days, making it highly radioactive.
- It is most commonly used in the treatment of hyperthyroidism i.e Thyroid therapy.
The radioisotope Phosphorus-32 is used in leukemia therapy as well as diagnostic purposes.
Carbon-14 is a beta emitter radio active isotope of carbon and is used in radiocarbon dating and radiolabeling.
