Question

Radioactive isotopes are used in various fields like medicine, agriculture etc. List the role of following.a) Carbon-14 B) Sodium-24.​

Answer 1

Answer:

Explanation:

CARBON - 14

          Radiocarbon dating ( CARBON - 14) involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content. Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies. Carbon-14 is also passed onto the animals that eat those plants.

SODIUM - 24

         It can therefore be used to monitor goiter and treat thyroid conditions, such as Grave’s disease, as well as liver and brain tumors. Salt solutions containing compounds of sodium-24 are injected into the bloodstream to help locate obstructions to the flow of blood.
