Valley’s physicists are responsible for developing and directing quality control programs. They are responsible for the daily operation and safety of equipment and procedures. 


Dosimetrists carefully calculate doses of radiation to ensure each tumor is effectively treated, using the amount of radiation that will best destroy the tumor and spare normal tissue. Dosimetrists work with the radiation oncologist and the physicist to choose the most appropriate treatment course for each patient.
