Radiation Therapist Monday to Friday 7am to 3.30pm Location: 7 Richland Medical Park Dr. Columbia Prisma Health Floating Policy for Contracted Staff Prisma Health s goal is to keep staff in their home unit. However it is a requirement for all assignments that agency staff regardless of unit or facility must float to other Prisma Health units and/or campuses per request due to census concerns. Staff will only be floating to units they are qualified for and performing tasks for which competencies have already been demonstrated and documented.
