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.
