Satish Nair, Ph.D, CHP, DABMP

Satish joined Frank’s group in the summer of ’99, straight out of grad school, where he had functioned as assistant radiation safety officer for a couple of years. He brought with him a checkerboard of academic backgrounds, including biology, environmental science, analytical chemistry, aquatic toxicology and biochemistry. Largely self-taught in physics, he subsequently got himself board certified as health physicist by the American Board of Health Physics, and then as medical physicist by the American Board of Medical Physics. He later closed the loop with a Master’s in Health Physics.  Satish’s areas of interests are in regulatory compliance evaluation of all manner of diagnostic imaging equipment, both clinically and for device manufacturers; preparing educational materials for technologists and physicians, designing and maintaining equipment survey forms; DOT regulations and IEC Standards. He specializes in accreditation testing for mammography, computed tomography and nuclear medicine modalities. When Satish is not working, he may be spotted in some remote corner of the globe, pursuing his passion for landscape and wildlife photography.

(Retired) Frank Massé B.Sc., CHP, FHPS

Frank is a graduate of Northeastern University’s Co-Op Physics program and in the early days of Nuclear Medicine was assigned to the Neurosurgery Department at Tufts-New England Medical Center as a Co-Op Medical Physicist. After graduation he joined Tufts NEMC Physics Department and was appointed to the federally-mandated position of Radiation Safety Officer overseeing both clinical and research use of radioactive materials as well as diagnostic and therapeutic xray uses, which position he still holds today. After 7 years at T-NEMC, Frank was recruited to a senior position in the Radiation Protection Program at MIT where he served for 41 years, retiring in 2000 as Institute Radiation Protection Officer, Bates Laboratory Radiation Protection Office, and Director of MIT Radiation Protection Programs. He continues to serve on the MIT Radiation Protection Committee, the MIT Reactor Safeguards Committee and the MIT Institutional Review Board overseeing human research studies. With consulting privileges at MIT, he continued to serve as Radiation Safety Officer at Tufts Medical Center throughout the MIT years and gradually accepted other consulting assignments as he was sought after by hospitals, universities and xray equipment developers and manufacturers. He incorporated F.X. Massé Associates, Inc. in 1975 to consolidate his consulting activities and facilitate the organization of a team to meet expanding demands. He has been involved in the development of CT and other emerging diagnostic xray modalities, accelerator systems and xray surveillance equipment, and has conducted performance evaluations on all types of medical and industrial xray equipment, including prototype measurements for initial FDA product marketing filings. He has been active in State and Federal advisory committees and spent more than 30 years in NBS, NIST, ANSI ionizing radiation Standards activities. Frank was certified by the newly organized American Board of Health Physics in 1962 and by the American Board of Medical Physics in 1989, when that Board was first formed. He is a Charter Member of the American Association of Physicists in Medicine and a Life Member of the Health Physics Society where he has held many committee assignments as member or chair, and served more than a decade on the Board of Directors and as Treasurer and President.

(Retired) Gail A. Magenis, M.Sc.

Gail received her bachelor’s degree in Zoology from Connecticut College in New London, CT and master’s degree in Radiological Health and Protection from the University of Miami, FL.  She worked as a research assistant in genetics, first at Shields Warren Radiation Laboratory in Boston, then at The University of California in San Francisco, and finally back in Boston, where she worked in a similar capacity at the Robert Breck Brigham.  After receiving her Master’s degree, she went to work at MIT’s Radiation Protection Office as an Assistant Radiation Protection Officer supervising technologists and working primarily with the Biology Department personnel.    Gail has been with F.X. Masse Associates Inc. since its incorporation in 1975, initially performing routine x-ray system performance evaluations as well as Nuclear Medicine regulatory compliance surveys.  Later she focused on those clients with Nuclear Medicine and Nuclear Cardiology programs.  She provided education to the clients’ workers about radiation exposure as well as providing regulatory support.  In that context she served as  Radiation Safety Officer for Navix Diagnostix and for the Cape Cod Hospital programs.
