What experimental parameters help protect those who work regularly with radioactive materials and why? Radioactive decay is an inherently random process. In order to make our radiation counting measurements better, what could you do to increase the precision of your measurements? If the radioactive samples are not brand new, then how does the relative age of the sample affect your measurements?
