WebThe half-life of the samples is not given. So, let's take internet value. The half-life of 223 Ra is t R = 11.435 days. The half-life of 47 Ca is t C = 4.536 days. And the time interval is t = 4.00 weeks = 28.00 days. Suppose the number of initial atoms of radium is N Ri = n and of calcium atoms is N Ci = 2n. Now, the number of half-lives in 28 ...
