16 Mar 2015 ICRP Seminar Convened

The ICRP Lecture series started upon signing of the Memorandum of Understandings by FMU and ICRP on February 19 of 2014. On March 16 2015, the 4th ICRP Lecture was given by Dr. Nobuhiko Ban, the ICRP Committee 1 member and Professor at Tokyo Healthcare University and Mr Chris Clement, Scientific Secretary of ICRP.

Dr. Ban talked under the title of “About the ICEP System of Radiological Protection” and overviewed the ICRP System of Radiation Protection (RP) which was revised in 2007. He discussed the overall framework of RP, exposure situations and the principles developed by ICRP. The framework of the ICRP system of RP is built on the recognition of health detriments brought about by radiation and the nature of dose responses with and without threshold. The system of RP recommended by ICRP is context dependent in that the system differs by the three exposure situations of planned, emergency and existing exposure situations, and by the three categories of occupational, medical and public exposures). Application the ICRP RP system also has to follow the three principles, justification, optimization and lose limits.

Mr. Christopher Clement talked under the title of “The System of Radiological Protection in Medicine”. He began his talk by introducing a strong commitment of ICRP on this medical field since the largest dose to the people in the world comes from the medical use of radiation. Thus the three principles of RP are particularly important in applying the ICRP RP system in the use of radiation in medicine. He focused on the use of radiation in the field of the interventional cardiology in which the dose can be substantial such as a few Gy to the heart region. Even with the dose high enough to cause skin burns and resulting ulcers, such use of radiation is justified since the use is essential to save the life of the patient, demonstrating how the balance between risk and benefit can be justified and optimized.

16 Mar 2015 “Seminar: Fukushima Nuclear Disaster and Health Risk Management” Convened

This Seminar was held on 16 March 2015 at Sendai City Silver Center in Sendai City. It was a Public Forum associated with the Third United Nations World Conference on Disaster Risk Reduction. This seminar was one of about 400 events held during the UN conference. About 50 people participated in this seminar.

The first lecture, by Professor Kenneth Nollet, was “Health Status of Fukushima Residents after the Nuclear Accident.” He explained the Fukushima Health Management Survey, a comprehensive and scientific survey of people in Fukushima after the earthquake, tsunami, and nuclear crisis. The interim outcome of this survey is released about 4 times in a year on line.
His slides are here.

The second lecture, by Professor Arifumi Hasegawa, was “Medical Response to the Fukushima Daiichi Nuclear Power Plant Accident at Fukushima Medical University Hospital.” Drawing lessons from our response, he recommended the following:
◾Maintain awareness of the risks around us
◾Exercise precautions for predictable risks
◾Minimize uncertainties to the extent possible
◾Learn from experience and history
◾Acquire knowledge and skill

His slides are here.

The third lecture, by Dr. Atsushi Kumagai, was “Risk Communication after the Radiation Disaster; Living Safely and Soundly in Fukushima.”
His points include the following.
◾Purpose of risk communication is
1. To support citizens’ understanding of level of risk.
2. To support citizens’ own decision-making.
◾Communication patterns will change with time
1. Crisis → Post Crisis → Before Accident
◾Sympathy-based communication vs. Data-based communication
◾Medical professionals are the best suited to address radiation anxieties.
◾Being an expert during a crisis is much more than delivery of information.
◾Comprehensive support is essential. It requires humanity and liberal arts.
