In radioactivity,we say that half of the amt. of a radioactive substance decays in 1 half life,but how do we determine this original amount?-Suppose we have 2 samples of a radioactive substance,separated by a distance of 1mm.Will they decayseparately ,or is the original amt. the sum of the 2 samples?
