Will AI replace Radiation Therapists?

AI can do 28% of the work Radiation Therapists do at least twice as fast. Real use has not caught up: none of their tasks show up in real AI use yet, but AI could speed up 7 of them. Robots can technically handle 7 physical tasks. 8 still need a person.

AI is already doing this0 · 0% of time

People already use AI for these tasks in real work, based on Anthropic's analysis of how Claude is used.

  • Real AI use has not reached any of this job's tasks yet.

AI could do this next7 · 28% of time

AI can speed these up by at least half, but real use has not caught up yet. These are next in line.

  • Enter data into computer and set controls to operate or adjust equipment or regulate dosage.8% of time
  • Maintain records, reports, or files as required, including such information as radiation dosages, equipment settings, or patients' reactions.6% of time
  • Observe and reassure patients during treatment and report unusual reactions to physician or turn equipment off if unexpected adverse reactions occur.5% of time
  • Help physicians, radiation oncologists, or clinical physicists to prepare physical or technical aspects of radiation treatment plans, using information about patient condition and anatomy.3% of time
  • Act as liaison with physicist and supportive care personnel.3% of time
  • Schedule patients for treatment times.3% of time
  • Implement appropriate follow-up care plans.1% of time

Robots can technically do this7 · 46% of time

Physical tasks that today's robots can perform in at least some settings. Robots are cost competitive for very few tasks so far, so this change moves slower.

  • Position patients for treatment with accuracy, according to prescription.Robots: purpose built settings18% of time
  • Administer prescribed doses of radiation to specific body parts, using radiation therapy equipment according to established practices and standards.Robots: structured workplaces15% of time
  • Check radiation therapy equipment to ensure proper operation.Robots: purpose built settings5% of time
  • Conduct most treatment sessions independently, in accordance with the long-term treatment plan and under the general direction of the patient's physician.Robots: purpose built settings4% of time
  • Photograph treated area of patient and process film.Robots: structured workplaces4% of time
  • Store, sterilize, or prepare the special applicators containing the radioactive substance implanted by the physician.Robots: purpose built settingsunder 1% of time
  • Assist in the preparation of sealed radioactive materials, such as cobalt, radium, cesium, or isotopes, for use in radiation treatments.Robots: purpose built settingsunder 1% of time

Still needs a person8 · 27% of time

No real AI use, no proven AI speedup and no robot that can do it yet. This is the part of the job to build on.

  • Review prescription, diagnosis, patient chart, and identification.6% of time
  • Educate, prepare, and reassure patients and their families by answering questions, providing physical assistance, and reinforcing physicians' advice regarding treatment reactions or post-treatment care.5% of time
  • Check for side effects, such as skin irritation, nausea, or hair loss to assess patients' reaction to treatment.4% of time
  • Prepare or construct equipment, such as immobilization, treatment, or protection devices.4% of time
  • Follow principles of radiation protection for patient, self, and others.3% of time
  • Provide assistance to other healthcare personnel during dosimetry procedures and tumor localization.3% of time
  • Calculate actual treatment dosages delivered during each session.1% of time
  • Train or supervise student or subordinate radiotherapy technologists.1% of time

What this means

AI can speed up parts of this job, mostly the paperwork and information work around it. The core still depends on hands, presence or relationships. Robots are the other change to watch: they can technically do 46% of the working time.

What to do next

  • Get ahead on the 7 tasks AI could do next. These move as tools improve, so learning them early pays off.
  • Keep an eye on the 7 physical tasks robots can technically do. Cost keeps most robots out of work today, so this shift is slower.
  • Build on the 8 tasks that stay human. This is where your judgment, skill and relationships matter most.
