Radiation Therapists

Radiation therapists are typically part of a cancer management team. They record, interpret and administer the treatments prescribed by a radiation oncologist. They utilize a variety of equipment such as cobalt units and linear accelerators. During a patient's treatment, radiation therapists help doctors use X-ray films, fluoroscopy or CT scans and outline anatomic areas that require treatment. They help locate tumors, update treatment reports and measure the amount of radiation.

Radiation therapists are in continual contact with patients during their course of treatment and provide education about the treatments and simulation procedures and explain the potential radiation side effects. Radiation therapists need to adhere to regulated standards in order to protect patients and practitioners from high doses of radiation. They also monitor a patient's progress and emotional needs.

  • Use internal images to find the precise location of the cancer
  • Observe and document the reaction of patients to their treatments
  • Look out for the safety of patients
  • Monitor the physical condition of the patient during the treatment phase
  • Answer patients' radiology questions
  • Maintain equipment
  • Follow all safety regulations regarding radiation exposure
  • Operate linear accelerator
