Vacancy rates are falling for radiation therapist and medical dosimetrist positions, according to the American Society of Radiologic Technologists' (ASRT's) 2026 Radiation Therapy Workplace and Staffing survey.

The biennial survey showed a vacancy rate of 11.4% in 2026, compared to 13.6% in 2024, while the vacancy rate for medical dosimetrists fell to 6.8% this year from 9.6% in 2024, according to the ASRT.

ASRT's survey also found that the average number of full-time equivalent (FTE) radiation therapist positions budgeted per facility decreased slightly from 8.3 in 2024 to 8.1. Meanwhile, FTE dosimetrist positions budgeted per facility increased from 2.7 to 2.8 in 2026, ASRT said.

The survey was conducted in February 2026. Of 23,145 radiation therapists and medical dosimetrists approached, 560 responded.

$Acute radiation-induced pneumonitis after SBRT (65 Gy, four fractions) in a 53-year-old woman with leiomyosarcoma of the uterus with a left lower lobe metastasis manifesting as a small nodule (not shown). (A) Axial dosimetric reconstruction of a CT image obtained for SBRT planning shows the metastasis receiving the maximal isodose (6500 cGy). (B) Axial CT image obtained 12 months after completion of RT shows focal ground-glass and consolidative opacities confined to the treatment plan (arrow). Note that acute lung injury with SBRT typically manifests later than with conventional RT (i.e., >12 weeks after completion of therapy), and in 25% of patients, the first CT manifestations occur more than one year after completion of RT.$
