In the original article, he suppose that nuclear plants are on the rise due to climate change policies, so maybe there will be a demand for gamma ray sensing in environment, to monitor leakage... The idea I extrapolate from his work is that you can plant its potatoes around the plant and control it from a reasonable distance with fluorescent sensors, in relatively large areas. Or put some potatoes in officies and see if it start to glow.
