Vacancy rates for radiation therapists declined in 2012, according to the American Society of Radiologic Technologists (ASRT) Staffing & Workplace Survey 2012.

Survey results showed that the vacancy rate for radiation therapists fell to 2.1 percent in 2012, down from 3.1 percent in 2011. However, the vacancy rate for medical dosimetry rose slightly from 4.9 percent to 5.1 percent during the same period.

The staffing survey also provides information about the average number of full-time radiation therapists and medical dosimetrists working in medical facilities. The survey results showed that the average number of medical dosimetry positions increased slightly from 2.1 per facility in 2011 to 2.5 in 2012. However, the average number of full-time radiation therapists has remained at 7.4 per facility since 2011, ASRT said.
