the affected Chernobyl area 100 times. According to Yamashita, the communication with the children whose age was the same as his own, and their mothers, made him feel as if the area was next to Nagasaki. He eventually concluded the effects of radiation in the area as follows: “Apart from the dramatic increase in thyroid cancer incidence among those exposed to radiation at a young age, there is no clearly demonstrated increase in the incidence of solid cancers or leukemia due to radiation in the most affected populations”. Efforts to reduce radiation exposure in medical treatment Before the nuclear crisis in Fukushima, Yamashita showed his concern about the radiation dosage to which young people were exposed. In The Journal of Japan Physicians Association, he writes: “Mainly for the people less than twenty-years-old, if they are exposed to excessive radiation between 10 and 100mSV, the risk of carcinogenesis is undeniable”. The other report written with other scientists points out, “the lowest doses of X-rays for which reasonably reliable evidence of increased cancer risk exists range from 10 to 50mGy”. Relationship with the Catholic church Being Catholic, Yamashita has been involved with activities held in the Catholic Church. For example, when the first general assembly of the Conference of Japan Catholic Medical Care Associations was held in Nagasaki from October 23 to October 24, 2009, Yamashita said, "As Hiroshima and Nagasaki are the only cities in the world that were afflicted with A-bombings, both can claim the moral high ground on A-bomb elimination. No one can deny their claims and international diplomatic endeavors on behalf of peace free of nuclear weapons. U.N. General Assembly President Miguel d'Escoto referred to this right when he visited Japan last summer." Even after his appointment to risk management advisor to Fukushima Prefecture, the Church's attitude toward the professor remains unchanged. In Saitama Diocese, the diocesan Committee for Justice and Peace led by Sadato Yabuki, a diocesan deacon and professor emeritus at Gunma University, invited Yamashita to lecture on radiation at the cathedral on May 7, 2011. Later, In the name of Bishop Marcelious Daiji Tani, leaflets based on the lecture were printed in six languages and distributed in the diocese and shelters. When he was installed as a vice-president of Fukushima Medical University, the diocesan newsletter called Yoki Otozure (Good Visit) in the Nagasaki Archdiocese reported this event. In November, a symposium, “Radiation Exposure” Which Causes
