If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Vedclass · Answer

(A) ${}^{90}Sr$ is chemically similar to calcium and is absorbed by the body,accumulating in the bones. Red blood cells $(RBCs)$ are produced in the bone marrow. The energetic $\beta$-particles emitted during the radioactive decay of ${}^{90}Sr$ damage the bone marrow tissue. This damage leads to a significant reduction or impairment in the production of red blood cells. Therefore,the Reason correctly explains why the Assertion is true.

Assertion: ${}^{90}Sr$ from the radioactive fallout of a nuclear bomb ends up in the bones of human beings through the milk consumed by them. It causes impairment of the production of red blood cells.
Reason: The energetic $\beta$-particles emitted in the decay of ${}^{90}Sr$ damage the bone marrow.
