Biography

Dr. Borak is a professor on the faculty of the Department of Environmental and Radiological Health Sciences at Colorado State University.  He received a Bachelor of Science Degree in physics from St. John’s University (Minnesota) and a PhD degree in physics from Vanderbilt University.  is a professor on the faculty of the Department of Environmental and Radiological Health Sciences at Colorado State University.  He received a Bachelor of Science Degree in physics from St. John’s University (Minnesota) and a PhD degree in physics from Vanderbilt University. 

At Colorado State University, he has been a mentor and academic advisor to over 60 MS and PhD candidates.

His research interests are in radiation physics and dosimetry including radiation safety for uranium miners deep within the earth, to astronauts during space missions beyond the earth. 

Previously he has had scientific staff appointments at Fermilab, CERN, and Argonne National Laboratory. 

He has been a consultant to the Governor of Colorado concerning issues relating to low-level radioactive waste management and nuclear criticality safety.  He is a Certified Inspector and Certified Expert of radiation producing devices for the Colorado Department of Public health and Environment. 

Dr. Borak was a member of the National Academy of Sciences Committees on Risk Assessment of Exposure to Radon in Drinking Water (1999), An Assessment of the Scientific Information for the Radiation Exposure Compensation Act (2005), and Airport Passenger Screening using Backscatter X-Ray Machines (2015).  He is currently a distinguished emeritus member of the National Council on Radiation Protection and Measurements (NCRP) and is certified by the American Board of Health Physics.
