1.	One of the products of radiation fall out from atmospheric bomb testing or nuclear accidents at Chernobyl is iodine-131 . People living in a region where Iodine-131 was known to have been deposited were encouraged to use table salt enriched with non-radioactive isotope of iodine . By use of non-radioactive iodine isotope in common salt :
Answer» rate of iodine - 131 UPTAKE is sharply reduced compared to uptake of iodine -127 a new non-radioactive isotope is formed taste of table salt BECOMES better iodine -131 being water soluble is eliminated from TISSUE . Solution :Displacement of `I^(127)` leads to EXCREATION of `I^(131)` from HUMAN body .
