Question 57

To locate a suspected fracture in a subterranean municipal water pipeline, engineers introduce a gamma-emitting radioactive tracer at the source and monitor the flow along the pipeline. This scanning procedure requires continuous detection of radiation over a period of 8 hours.

State why a radioactive tracer with a half-life of 40 minutes is not suitable for this investigation.
