How long would it take a sample of this isotope to decay to just 51.467% of its original activity?
Q. The isotope 228-Ra has a half life of 1602 years. How long would it take a sample of this isotope to decay to just 51.467% of its original activity?
Asked by Linda B - Tue Apr 1 08:06:50 2008 - - 1 Answers - 0 Comments
A. halflife is 1602 years, or decay of 50% of activity if x is the original activity after 1602 years--- x/2 remains needs to decay 2(1.46%) by ratio and proportion 1602/50= y/(2*1.467) y=94 years total years= 1602+94 = 1696 yrs( ans)
