If a radioactive element in a sample has decayed until 1/8th of the original amount is present in the sample how many half-lives have occurred? Show your work.
All of the isotopes of Radon have half-lives shorter than four days. However, there is always Radon around us. Hypothesize why there is always Radon present around us.
A certain isotope of Technetium has a half-life of six hours. If it is given to a patient as a part of a medical procedure to track chemicals in their blood, what fraction of the radioisotope remains after 1 day? think about how many hours r in 1 day, go from there
