WebThe dearth of modern studies on radium has many origins. First, the only moderately long-lived isotope that is potentially available is 226Ra (t½ = 1620 years). A half-life of this timescale renders the specific activity of even microgram samples quite high and makes manipulation of samples challenging. WebUse a half-life of 1620 years, as shown in the next Figure. SOLUTION Let y represent the mass (in grams) of radium in the sample. y=Cektwheretis measured in years. We are given the following values for the function y : y = 1 whent =0, and y = 1/2 when t =1620. Applying the first of these conditions, we have y=1=Cek(0) t =0 Thus, C =1.
