This caused me to flash on the solution to a vexing problem. When water and sewer lines are buried in a subdivision-under- construction, mischievous kids will often pull up the poles the crews use to mark their terminal connection points. They are then a real time-consuming bitch to relocate. If small radioactive isotopes are planted in the pipes' endcaps, they can be located with geiger counters.
