question 15

Essay

$${ } ^ { 137 } \mathrm { Cs }$$ is a common and particularly troublesome fission fragment produced in thermal neutron reactors. The difficulty with ${ } ^ { 137 } \mathrm { Cs }$ arises because of its long half-life $( 30$ years) in the $\beta$ decay chain (Figure $6.6$ ). Calculate the time required for ${ } ^ { 137 } \mathrm { Cs }$ in nuclear reactor waste to decay to $10 ^ { - 6 }$ of its original activity.
