Your pet bats, Joe, Bob and Curly love coffee.Unfortunately,after their Saturday morning cups of coffee, you arehorrified tolearn that the coffee is laced with radioactive isotopeY. Openingthe window to let in some air 1 day later, two of yourbats (Boband Curly) escape, only to become a snack foryourneighbourâs pet falcon (who loves coffee drinkingbats.) By thetime you shoot the falcon 3.00 days later, youmeasure a total bodycount of 1,050,000 Bq, which is almost thesame count rate at thesame time for Joe (1,000,000 Bq). 1 Bq = 1Becquerel = 1disintegration per second. Joe drank 4 cups ofcoffee, Bob drank 2cups of coffee, Curly drank 3 cups of coffee,the physical half-lifeof radionuclide Y is 5.00 days, and theeffective half-life in thefalcon is 3.00 days.
(a) What is the biological half-life ofthisisotope in the falcon?
(b) What is the biological half-life ofthisisotope in the bat?
(c) What was the initial activity of a14-cuppot of coffee?
