With the increasing use of radiation and radioactive material in society, there is a growing need for research and advanced education in Radiological Sciences and Protection.


The Radiological Sciences option is one of several applied physics options that are designed to expand the scope of the Ph.D. degree in Physics at the University of Massachusetts Lowell (UML) to encompass a variety of disciplines in applied physics. This option is intended to develop original research contributions to the discipline of radiological sciences, and thereby advance the profession of radiation protection. 


For the Ph.D. degree in Physics, Radiological Sciences option, a minimum of 60 credits is required. Of these, at least 30 credits are for general and specific graduate courses (with a grade of B or better), at least 15 and at most 24 credits may be for dissertation research, at most three credits are for graduate colloquia and seminars, and (if necessary) six credits are for the successful completion of two semesters of advanced project research.

In addition, doctoral students are required to pass a Ph.D. Comprehensive Examination by the end of their first year of doctoral studies, and to write and defend successfully a Ph.D. dissertation at the end of their doctoral studies.

Workforce Shortages

Over the last few decades the Radiological Sciences field has seen a drastic decline of the workforce while the use of radiation continues to increase.

This has resulted in many opportunities for our trained Health Physicists working in the radiation protection sectors across the globe.
