Here are some basic guidelines on RAI from the ATA:

They have some general guidelines on how long to stay away from people, etc. but the specifics for you should come from your doctor (or a doctor of nuclear medicine) based on your dose.
You have some very specific questions and you should try to get those answered by your doctor before Tuesday afternoon.
By the way, Kimberly is traveling a bit this weekend so I’m not sure how prompt she will be at replying to your post.
