Question

Read the following short-up and give the answer to the given question.

People living in a region where iodine - 131 was known to have been deposited were encouraged to use table salt enriched with a non-radioactive isotope of iodine.

By use of non-radioactive iodine isotope in common salt __________.

• A. rate of iodine - 131 uptake is sharply reduced compared to uptake of iodine - 127
• B. a new non-radioactive isotope is formed
• C. test of table salt becomes better
• D. iodine - 131 being water soluble is eliminated from tissue

Answer 1

Answer: (A)

rate of iodine - 131 uptake is sharply reduced compared to uptake of iodine - 127

By the use of non-radioactive iodine isotope in common salt, the rate of iodine-131 uptake is sharply reduced compared to the uptake of iodine-127.

People living in a region where iodine-131 was known to have been deposited were encouraged to use table salt enriched with a non-radioactive isotope of iodine.

Due to this, the ratio of non-radioactive iodine to radioactive iodine present in the human body will be high. This minimizes the harmful effects of radioactive iodine.

Hence option- (A) is correct.
