Depending on the results of his next PSMA PET scan, my husband will be turning to Pluvicto as his next treatment option. I have been monitoring this subject line for helpful hints to deal with it. I have read 2 people with first hand knowledge - both of them had gotten Geiger counters "to be sure" (I believe one had said that he had found it on-line for < $100). They would stay in separate bedrooms until their readings dropped enough - one of them said that it would take him a week to get to a reading of zero. I plan on going with a Geiger counter.
We also will have to find a way to keep the cats away from him.
