I stayed at the hospital for 2 days (only one night). I was admitted around 10am, got my radiation pill around noon then the following day around 1pm I left. The hospital had this machine that would measure the radiation levels. When I hit a safe level they sent me home. I still couldn't get closed to people or animals for 8 more days. I had to sleep in the guest room away from my wife and dog. It's not that bad.....though it gets very boring in the hospital.
