`.^90 Sr` from the radioactive fall out from nuclear bomb ends up in the bones of human being through the milk consumed by them. It causes impairment of the production of res blood cells.
The energetics `beta-`particles emitted in the decay of `.^90 Sr` damage the bone marrow.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reasonb is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Both assertion and reason are true reason is the correct explanation of assertion.
`.^(94)Sr` from `.^(235)U` fission is absorbed through milk. Their emission of `beta^(-)` particles will damage the bone-marrow as Sr is absorbed in bones.
