Professor


Research Interests:
  • Radiation Physics
  • Dosimetry
  • Courses Taught:
    Current Research:
  • Skin Cancer Project - Comparing the risks for skin cancer and lung cancer from 222Rn decay products: There has been a suggestion that ambient conditions in underground mines might cause cancers at sites other than the lung. Specifically, it was suggested that radon daughters in the ambient air might be responsible for an excess risk of skin cancer. This project determined the dose and risk to basal cells in the epidermis from plate-out of Rn daughters on the skin as a function of Working Level Month (WLM). This is then compared to the projected risk of lung cancer per WLM.
  • Research Projects 1 - Microdosimetry of high energy heavy particles: This research, sponsored by NASA, is related to dosimetry of cosmic radiation during manned space missions. We are measuring the response of tissue equivalent proportional counters (TEPC) to beams of particles such as 56Fe, 18Si, 12C, 4He, and high energy neutrons that are produced at the NASA Space Radiation Laboratory in Brookhaven National Laboratory and the Heavy Ion Medical Accelerator at the National Institute of Radiological Sciences (NIRS) in Japan. This work is in collaboration with physicists from the Lawrence Berkeley National Laboratory and NIRS.
