Radiation Therapy Technology

The two programs I can be filled in radiotherapy technology, and Diagnostic Medical Sonography. Could someone tell me from their own knowledge to become registered after completing the program?

Basically, how long does it take, how to prepare yourself, and should start work in the meantime?

Thank you! :)

Hopefully radiation therapy and ultrasound technology will respond with more details, but I just wanted to give you some links where you can find some answers:
