Radiation Therapist/Dosimetrist

Radiation therapists/dosimetrists work closely with medical physicists and radiation oncologists throughout New Brunswick. These qualified professionals provide radiation therapy services to treat patients with certain medical conditions, on the order of a physician. Using ionizing radiation, they can destroy diseased cells in the body, with dosimetrists specifically responsible for determining proper doses. This treatment is most commonly used to fight cancer and other life-threatening illnesses. It is a significant, crucial role in New Brunswick’s healthcare system.

A successful radiation therapist/dosimetrist has a broad combination of skills to carry out the duties and responsibilities of their position.

Like most healthcare professionals, when working with the public they must be empathetic, approachable, and understanding of their patients’ needs. Lifting and moving patients is also a regular component of the job, so they must stay in good physical shape.
