Medical Dosimetrist

Overview:
To be part of our organization, every employee should understand and share in the YNHHS Vision, support our Mission, and live our Values. These values - integrity, patient-centered, respect, accountability, and compassion - must guide what we do, as individuals and professionals, every day.

Under the general direction of the Chief Medical Dosimetrist, work from information furnished by physicians for planning the radiation treatment of patients. Develop and present a series of plans of therapy for appraisal and approval of the attending physician or group critique. Provide control liaison between the attending physician and therapist treating the patient. Initiate projects in additional areas which may include: formal teaching, research, in-service education or quality assurance.
