I'm sure you are looking forward to your husband getting this treatment. We have several discussions devoted to PRRT. I suggest you post this question about radiation, isolation, and tips for sanitizing in one of these groups. Here are the links:

--Post PRRT CT Scans
https://connect.mayoclinic.org/discussion/questions-regarding-post-prrt-ct-scans/
In these groups, you will meet @dbamos1945, @vinnie694, @markmark007, @kim1965, and @sophiarose, and many others who will be able to answer your questions.
