The primary functions of the PAC are to analyze mechanisms of interaction of nonionizing radiation with biological systems, including humans, and to identify biological responses and potential human health effects. Evaluations are made of both theoretical and applied aspects of dosimetry and exposure assessment of humans to nonionizing radiation, as well as procedures for mitigating exposure in public and occupational settings. Recommendations are also established on acceptable exposure levels for nonionizing radiation in occupational, medical and public environments.

MARTHA S. LINET
is currently an NIH Scientist Emerita since retiring in 2020 as Senior Investigator and former Chief of the Radiation Epidemiology Branch (2002 to 2014) in the National Cancer Institute. Dr. Linet’s research has focused on protracted low-dose radiation exposure and cancer risks in radiologic technologists and physicians performing fluoroscopically guided interventional procedures. She has also studied power-frequency magnetic field exposures in relation to childhood leukemia and cellular telephone use and risk of adult brain tumors. Dr. Linet is an internationally recognized expert on postulated risk factors for childhood and adult hematopoietic malignancies, including occupational benzene, medical conditions, medications, early life infections, and potential protective factors such as vitamin D and periconceptional folic acid supplements. Dr. Linet was a Council member of NCRP (2010 to 2016) serving on Scientific Committee 4-4 and is currently a Distinguished Emeritus. She was President of the American College of Epidemiology (2004 to 2005), a member of the National Academy of Sciences Nuclear and Radiation Studies Board (2011 to 2017), and has served on numerous national and international advisory groups and on Editorial Boards (American Journal of Epidemiology and the Journal of the National Cancer Institute).
Michael D. O’Hara
has served as the U.S. Food and Drug Administration (FDA) representative on the Advisory Committee on the Medical Uses of Isotopes since November 2014. Dr. O'Hara earned his BA in biology from D'Youville College in Buffalo, an MS in Natural Sciences from the State University of New York at Buffalo, and a PhD in Biological Sciences from Wayne State University in Detroit. He completed a postdoctoral fellowship in the laboratory of Experimental Radiation Oncology at Thomas Jefferson University in Philadelphia. He remained as a faculty member at Thomas Jefferson University Medical College in the Department of Radiation Oncology. He lead research efforts investigating the impact of chemical agents that modify the thermal response of normal and malignant tissues during thermal/radiotherapy and investigated bone marrow transplantation as a method to treat osteogenesis imperfecta. Dr. O'Hara regularly taught an undergraduate course in "Health Physics and Radiation Biology," lectured medical residents, and was a member of the Institutional Animal Care and Use Committee. Dr. O'Hara moved to Cordis [a Johnson and Johnson (J&J) company] to manage the firm's radiation therapy efforts involving radioactive endovascular stents and catheter-based radiation sources. He was promoted to a J&J Research Fellow and continued to assist Cordis and other J&J companies with radiation-based therapies. Dr. O'Hara joined FDA in 2004 in the Division of Biology in the Office of Science and Engineering Laboratories within the Center for Devices and Radiological Health (CDRH). His activities included research studies involving relative biological effectiveness of ionizing radiation and the radiofrequency (thermal) / radiotherapeutic response of human tumor cells. He also served as the chairman of the Animal Care and Use Committee and has served as a member of the Center for Devices and Radiological Health (CDRH) Radiology Standards Committee, the CDRH Radiofrequency Working Group, the Interagency Radiofrequency Working group and the Health and Human Services Radiation Biodosimetry Working Group. Dr. O'Hara served the Office of Device Evaluation and the Office of In Vitro Diagnostics as an Acting Branch Chief and later an Acting Deputy Division Director. He currently serves the Office of In Vitro Diagnostics and Radiological health as one of the Deputy Division Directors of the Division of Radiological Health. This division is responsible for the pre-market evaluation, post-market medical device reporting and compliance for all radiation emitting medical devices.
Martin Röösli received a MSc degree in Environmental Science in from the Swiss Federal Institute of Technology in Zürich in 1997 and a PhD in Epidemiology from the University of Basel in 2001. To date he is Associate Professor for Environmental Epidemiology at the Swiss Tropical- and Public Health Institute in Basel and leads the Environmental Exposures and Health Unit.
His research focuses on various environmental health topics with a focus on nonionizing radiation exposure and health risk assessment. In the field of EMF he has led or was collaborator in numerous studies such as ARIMMORA (Advanced Research on Interaction Mechanisms of Electromagnetic Exposures with Organisms for Risk Assessment), CEFALO (An international case-control study on brain tumours in children and adolescents), QUALIFEX (Radio frequency electromagnetic field exposure and health related quality of life: prospective cohort study) and GERoNiMO (Generalised EMF Research using Novel Methods – an integrated approach: from research to risk - assessment and support to risk management).
Currently, his research group is involved in the European Union funded projects ETAIN (https://www.etainproject.eu/) and GOLIAT (https://projectgoliat.eu/) as well as the Swiss monitoring project SwissNIS.
He has served as advisor to a number of national and international public advisory and research steering groups concerning the potential health effects of exposure to nonionizing radiation, including the World Health Organization and the International Agency for Research on Cancer. Currently, he is the chair of the Swiss expert group BERENIS (Swiss Expert Group on Non-Ionising Radiation), and member of ICNIRP (International Commission for Non-ionizing Radiation Protection), of the German Radiation Protection Commission (Non-ionizing Radiation (A6) and working group 5G (A630)) and the Independent Expert Group of the Swedish Radiation Safety Authority. He was member of the Scientific Council of the European Bioelectromagnetics Association from 2009 to 2017.
