Theoretical Activities

Ba-133, 9.821 uCi on April 7, 2015, half life 10.51 years, 32.9% for 80.9979 keV line,activity in April 18, 2017 =8.589 uCi

= [math]\left (0.329 \right )\left ( 8.589 \times 10^{-6} \mbox{Ci} \right) \left (\frac{ (3.7 \times 10^{10} \mbox{Hz}}{\mbox{Ci}} \right)= 107840.607 Hz [/math] for the 80.9979 line
