is an isotope of iodine that decays to an isotope of Xenon with a half-life of 8 days. A small amount of a serum labelled with is injected into the blood of a person. The activity of the amount of injected was Becquerel (Bq). It is known that the injected serum will get distributed uniformly in the blood stream in less than half an hour. After 11.5 hours 2.5 ml of blood is drawn from the person’s body, and gives an activity of 115 Bq. The total volume of blood in the person’s body, in liters is approximately
(you may use for and ln ).
i.e. initially.
For 2.5 ml we get 115 Bq
So for “V” vol. we get
