Enormous amounts of 131 Iodine 53 were released in the accident at Chernobyl in year 1986. Chemically, iodine goes to the human thyroid. In a normal thyroid, 131 iodine 53 absorption can cause injure to the thyroid.
i) Illustrate the reaction for the decay of 131 Iodine 53.
ii) Its half-life is 8d; determine how long it would take for the ingested 131 Iodine 53 to become 10% its initial value.
iii) Absorbing 1mCi of 131 Iodine 53 can be injurious; determine what mass of iodine is this?
