Treatment for hyperthyroidism with cesium-131. My cat had that treatment. They expel the cesium in their urine. I was required to sequester his litter for a week, and then store the rest for 80 days before providing it for garbage collection. Apparently, garbage dumps have radiation detectors to prevent accumulation of unwanted / illegal radioactive waste.
