Chinanews.com, Xiamen, June 11th: Four well-known marine scientists from the United States, France and China gathered at Xiamen University on the evening of the 11th to give a lecture on "Earth: Ubiquitous Nuclear Radiation-Truth and Misunderstanding". To discuss the truth and misunderstanding of marine nuclear radiation.
Plutonium scientists also conducted face-to-face exchanges with the participants to resolve concerns and concerns of the general public about nuclear radiation.
This event was co-sponsored by the State Key Laboratory of Offshore Marine Environmental Sciences of Xiamen University, Working Group 146 of the International Marine Scientific Research Committee-"Marine Radioactivity Research", and the Marine and Environmental Radiation Research Center of the Woods Hole Oceanographic Research Institute. Dr. Claudia Benitez-Nelson, Distinguished Professor from the University of South Carolina, Dr. Ken Owen Buesseler, Senior Researcher at the Woods Hole Oceanographic Institute, Researcher Sabine Charmasson, a Marine Biologist at the French Institute for Radiation Protection and Nuclear Safety, and a Cheung Kong Scholar from Xiamen University Professor Dr. Dai Minhan gave a popular science lecture on issues related to nuclear radiation that attracted much attention from the public.
Plutonium experts say that humans live on a planet where nuclear radiation is ubiquitous, and the environment on which they depend, such as breathing air, drinking water and eating food, may contain trace radioactive elements.
However, the experts 'risk assessment of nuclear radiation and the public's perception of nuclear radiation risk are quite different. The experts' conclusions come from experimental data, but the factors affecting the public's perception of nuclear radiation risk are complex and diverse, and many factors are possible Cause the public to amplify the risk of nuclear radiation.
CDr. Claudia Benitez-Nelson, Distinguished Professor at the University of South Carolina, USA, introduced the concepts of how to distinguish between radiation and radioactivity in a humorous way. She used the nuclear radiation detector to measure the nuclear radiation value in the environment on the spot, and told the audience that nuclear radiation is actually ubiquitous. The daily radiation exposure of one person in the daily life is 3 to 6 mSv, but all are within the safe range.
In the ocean, there are various radionuclides that are enriched by marine organisms, but they are enriched to different degrees in different organisms. Researcher Sabine Charmasson, a marine biologist from the French Institute for Radiation Protection and Nuclear Safety, assesses the pollution of the marine environment by detecting the enrichment of pollutants in marine organisms, and informs the public of the status of marine environmental pollution.
Dr. Dai Minhan, Distinguished Professor of Yangtze River Scholars at Xiamen University, with his rigorous scientific attitude, faced the doubts of the Chinese public and scientifically evaluated the impact of the Fukushima nuclear accident on China's adjacent waters. The marine and atmospheric data proved that radioactive materials in the China Sea The level is low and there is no evidence of the impact of the Fukushima nuclear accident or China's coastal nuclear power plants.
It is reported that the International Commission for Marine Science (SCOR) established the "Marine Radioactivity Research" Working Group in 2014, co-chaired by Researcher Ken Buesseler and Professor Dai Minhan, bringing together 19 scientists and educators from 16 countries to carry out The latest cutting-edge research and education on marine nuclear radiation, establish a comprehensive global database, look forward to providing accurate data to the public, and promote public education in this regard, filling the gap in public awareness.
