An isotope of Technetium has a half-life of 6 hours. If it is given to a patient as part of a medical procedure,
what fraction of the radioisotope remains in the body after one day?
Amount remaining=original amount(1/2)^(time/half life). We can say the original amount is 100, as in 100%. This means the formula would look like: amount remaining = 100(1/2)^(24/6). 100(1/2)^4= 100(0.075)=7.5% remaining
