ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Proton radiography imaging qualities have been studied using Monte Carlo simulations. A specific phantom, made of different common tissues, was implemented for simulations using the Massachusetts General Hospital treatment proton beam, pure 230- and 490-MeV proton beams, and a pure 100-keV X-ray beam. Along with spatial resolution, the signal-to-noise ratio and the contrast-to-noise ratio were specified and compared for each tissue type and geometry, using filtered radiographs taking into account only primary proton interactions, both primary and secondary proton interactions, and both contributions while performing angular and energetic cuts. This work particularly highlights the faculty for proton radiography to image both low- and high-density tissues. This could play an important role in diagnosing specific tumor types, such as lung cancer, for which conventional radiography operates poorly.
