JOSEPH BEVELACQUA, Treasurer
Joseph Bevelacqua is the Treasurer of the XLNT Foundation, an organization dedicated to overcoming the LNT model problem and facilitating full utilization of beneficial effects of radiation, for enhanced health.
Joseph Bevelacqua received his PhD in theoretical nuclear physics from Florida State University in 1976. He has over 100 publications in nuclear theory, high-energy theory, mathematical physics, gravitation, cancer therapy, and radiation protection/health physics. Dr. Bevelacqua is the author of three health physics textbooks with two in their second edition, and a fourth book to appear early 2016. He is a Certified Health Physicist, Registered Radiation Protection Technologist, and a Certified Senior Reactor Operator.
His books address a variety of health physics areas including contemporary as well as emerging topics. The most recent book reviews the nuclear fuel cycle including Laser Uranium Enrichment and Generation IV Reactors, nuclear terrorism, nuclear emergencies, medical imaging and therapy including advanced applications, public exposures including space tourism, and issues associated with radiation protection and nuclear safety regulations. The LNT hypothesis is an integral aspect of this work.
Dr. Bevelacqua was a key player in the Three Mile Island Unit-2 Recovery Program and served as a Radiation Safety Engineer, Emergency Preparedness Manager, Safety Review Group Manager, and Radiological Controls Director. He was also an Emergency Director for TMI-2 emergency response team.
Dr. Bevelacqua also participated in a variety of assignments at the Hanford Site and its cleanup program. He was a Senior Radiological Controls Technical Advisor, acting Environmental Director, and acting Assistant Manager for Environment, Health, Safety, and Quality for the Hanford Waste Tank Farms activities.
He has extensive experience in the commercial nuclear power industry and served as Health Physics Manager, Production Planning Manager, and Outage Manager at a commercial nuclear power reactor. He also has plant operations, training, nuclear safety, and emergency preparedness expertise through his reactor employment.
In 1990, Dr. Bevelacqua founded his small business to provide radiation protection services to the nuclear industry. Bevelacqua Resources has supported over 100 organizations including both domestic and foreign corporations. Government agencies, universities, hospitals, national laboratories, and private industry have utilized Bevelacqua Resources’ services.
His interest in the LNT hypothesis began as a physics undergraduate student during a radiation biophysics course. This interest intensified during various assignments in the radiation protection field including the accelerator, university, fuel cycle, research reactor, power reactor, environmental, and medical areas. The resources devoted to saving small radiation doses were apparent, but these dose savings were only justified if the LNT hypothesis was valid. Considerably fewer resources were being devoted to the safety and protection of workers from industrial hazards. Unfortunately, numerous industrial incidents including falls, trips, burns, fires, and load drops have occurred at nuclear facilities and led to worker injuries. The resources devoted to saving minimal dose would have been more appropriately devoted to real hazards rather a postulated radiological detriment.
As Dr. Bevelacqua’s research activities expanded to include cancer therapy using internal radiation-generating devices and vascular disruption using microspheres loaded with radioactive material, it became more apparent that the LNT hypothesis was in need of revision. There is considerable research supporting the beneficial effects of low doses of ionizing radiation which is in conflict with the LNT hypothesis. The updated atomic bomb data, studies supporting hormesis, importance of the human immune system in biological repair, and efficiency of DNA repair at low doses are additional evidence that suggest the LNT hypothesis is flawed.
