Summary
The 2017 radiation oncologist (RO) workforce survey shows increased female representation and technology use, but a shift from rural to urban/suburban practice. Concerns about RO oversupply and practice changes are noted.
Area of Science:
- Oncology
- Medical Workforce Analysis
- Health Services Research
Background:
- The American Society for Radiation Oncology (ASTRO) conducts periodic workforce surveys to understand the evolving landscape of radiation oncology.
- Previous surveys have identified demographic shifts and practice patterns, highlighting the need for ongoing monitoring.
Purpose of the Study:
- To present the 2017 ASTRO radiation oncologist (RO) workforce survey results.
- To identify key demographic, technology, and employment trends within the RO profession.
- To assess the profession's capacity to meet patient needs, ensure job satisfaction, and attract new talent.
Main Methods:
- An online survey was distributed to 3856 US RO members in spring 2017.
- The survey design mirrored the 2012 workforce survey to enable trend analysis.
- A 31% response rate resulted in 1174 individual responses from 726 practices.
Main Results:
- The mean age of ROs was 50.9 years, with increased female representation (28.9%) and decreased white representation (69.8%) since 2012.
- A decrease in rural practice proportion (12.6%) was observed, with increases in suburban (40.6%) and sustained high urban (46.8%) practice locations.
- Utilization of advanced technologies like stereotactic body radiation therapy and hypofractionation increased significantly, while low-dose-rate brachytherapy decreased. Concerns about RO oversupply were more prevalent than shortage.
- A notable shift occurred from private practice towards academic/university systems and nonacademic hospitals, with practice mergers/buyouts being a primary driver for employment changes.
Conclusions:
- While race and gender disparities in the RO workforce have narrowed, geographic disparities persist, with a concentration in urban and suburban areas.
- The radiation oncology workforce is transitioning from predominantly private practice to a more balanced distribution across private, academic, and hospital-based settings.
- These trends underscore the need for strategic interventions to ensure equitable access to radiation oncology care for all patients across the US.

Biological Effects of Radiation
17.9K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Radiation: Applications
1.8K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

Radiation Pressure: Problem Solving
844
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...

Generating Electromagnetic Radiations
7.1K
The German physicist Heinrich Hertz (1857–1894) was the first to generate and detect certain types of electromagnetic waves in the laboratory. Starting in 1887, he performed a series of experiments that confirmed the existence of electromagnetic waves and verified that they travel at the speed of light. Hertz used an alternating-current RLC (resistor-inductor-capacitor) circuit that resonated at a known frequency and connected it to a loop of wire. High voltages induced across the gap in...

Momentum And Radiation Pressure
2.5K
An object absorbing an electromagnetic wave would experience a force in the direction of propagation of the wave. This force occurs because electromagnetic waves contain and transport momentum. The force accounts for the wave's radiation pressure exerted on the object. Maxwell's prediction was confirmed in 1903 by Nichols and Hull by precisely measuring radiation pressures with a torsion balance. The measuring instrument had mirrors suspended from a fiber kept inside a glass container.
