Average Hospital Stay
- Limited visitation: Many hospitals do not allow children under 18 years old or pregnant women to visit a patient having implant radiation. They may visit after the implant is removed. If visitors are allowed, they will need to sit at least six feet from the bed. Visits will be limited to 10-30 minutes. Staff may place a shield beside the bed to protect visitors and staff from radiation exposure.
- Limited contact with the staff: The staff will be available to you at all times. They may speak to you from the doorway. They may also come and go very quickly to avoid excessive radiation exposure.
