1. The problem statement, all variables and given/known data Is there such experiment to detect pipe leakage using radiation? I have opted to use radio-isotopes conduct this experiment. 2. Relevant equations None 3. The attempt at a solution How do i go forward with designing this experiment, knowing that I can use radio-isotopes and a detector to detect the radiation released by the isotopes. The subject that is bugging me is writting out variables for the experiment.
