Radiation Therapy School

I have two questions:

Im trying to decide what school i should go to for my A.S. in Radiation therapy. Im waiting on Broward College, but have been accepted to Cambridge health science and Kaiser. Have anyone graduated from these schools and have any insights?

Also,

I have my B.S. in Business Management, would this help me getting into the Management field as a Radiation Therapist, or would I need a B.S. in Radiation Therapy?

I appreciate it in advance.
