Medical Dosimetrists
In short: today's best AI models could do about 80% of this job's working time (projected from METR's April 2026 measurement and Epoch's November 2026 index) if the work were set up for them, and about 81% by the end of 2028 if progress keeps its long-run pace. The people and hands-on work, about 19% of the time, stays with people.
Generate radiation treatment plans, develop radiation dose calculations, communicate and supervise the treatment plan implementation, and consult with members of radiation oncology team.

Medical Dosimetrists, now: of a 40-hour week, AI could take on 32 hours, 0 hours become checking its work, 0 hours are desk work it can't do yet, and 8 hours stay with people.
The largest pieces: Design the arrangement of radiation fields to reduce exposure to critical patient structures, such as organs, using computers, manuals, and guides (about 6 h); Develop radiation treatment plans in consultation with members of the radiation oncology team (about 6 h); Identify and outline bodily structures, using imaging procedures, such as x-ray, magnetic resonance imaging, computed tomography, or positron emission tomography (about 5 h).

Measured, not estimated: Anthropic's samples of Claude.ai conversations, each tied by a model to an O*NET task, from the Anthropic Economic Index. It says where Claude's use goes, not how much of this job's working time it covers, so it is not on the same scale as the reach above. The releases differ in their sample, their classifier and the smallest share they report (the June 2026 file rounds each task to a hundredth of a percent, so a smaller task reads as none), which is why a change of method starts a new line. At least 96% of each older release's task-tied use matched this site's tasks, and all of the newest. Claude.ai only, so use through other tools and other companies' models is not in it. Every job ranked.
Robots and the physical work
Anthropic rates 3% of this job's working time as physical work. For 3% of the working time, a robot has been shown doing most of the task somewhere: 3% in a purpose-built cell. 0.03 of 3, the 623rd highest of the 923 jobs.
- Not physical 97%
- In a purpose-built cell 3%
Anthropic's rating, not this site's estimate: Claude Opus 5, searching the web, rated each physical O*NET task by the kind of setting in which a robot it could cite (deployed, sold or demonstrated) does most of the task, weighted by its own estimate of each task's share of the time (What work can robots do?, September 30, 2026, data CC BY 4.0; every job ranked). A robot shown somewhere is not a robot in your building: cost, setup and safety decide that. The share within reach on this page still counts no body work. The robot behind each rated task is under the task below.

Questions about this job
- How much of the work of Medical Dosimetrists is within reach of AI now?
- An estimated 80% of the working time is within reach of AI models now and 81% by the end of 2028, on METR's long-run pace at four in five. Within reach means a model could finish work that long at that reliability. It is not a forecast of jobs lost or of savings.
- Which tasks of Medical Dosimetrists come within reach first?
- Weighted by the time each takes, the tasks with the most within reach now (projected from METR's April 2026 measurement and Epoch's November 2026 index) are: Design the arrangement of radiation fields to reduce exposure to critical patient structures, such as organs, using computers, manuals, and guides (100% of the task's time now); Develop radiation treatment plans in consultation with members of the radiation oncology team (97% of the task's time now); and Identify and outline bodily structures, using imaging procedures, such as x-ray, magnetic resonance imaging, computed tomography, or positron emission tomography (99% of the task's time now).
- Which tasks of Medical Dosimetrists stay with people?
- Tasks that are people work or body work are not counted as within reach at any date. The largest: Fabricate beam modifying devices, such as compensators, shields, and wedge filters; Supervise or perform simulations for tumor localizations, using imaging methods such as magnetic resonance imaging, computed tomography, or positron emission tomography scans; and Teach medical dosimetry, including its application, to students, radiation therapists, or residents. Together such tasks are about 19% of the working time.
- Do people already use AI for the work of Medical Dosimetrists?
- In the Claude.ai conversations Anthropic sampled for May 2026 and tied to a work task, 0.17% went to this job's tasks, the 114th largest share of the 447 jobs that showed up; 1 of its 19 tasks appeared. These are measures of use, not of how much of the work AI could finish, and they cover Claude only.
- Can robots do the physical work of Medical Dosimetrists?
- Anthropic's robot exposure rating (September 2026) finds 3% of the working time is physical work, and that a robot has been shown doing most of the task, somewhere, for 3% of the working time. Its index is 0.03 of 3. One example: Nuclear Medicine Medical Isolation Ward Mobile Robot, model TMI-MD-NM-P for "measure the amount of radioactivity in patients or equipment, using radiation monitoring devices". A robot shown somewhere is not one in every workplace; this site's own estimates still count no physical work as within reach.
- How is this estimated?
- From the 19 tasks O*NET lists for the occupation, each with an estimated length checked against GDPval and a share of the working time, each classed as desk, people or body work, and METR's measurements of how long a task the best AI models can finish, carried forward to the date from the latest, Claude Mythos Preview (early) in April 2026. Data checked November 10, 2026.
