Most of these criticisms come from the memory of the bombings of Hiroshima and Nagasaki, where many Japanese lost their lives and continue to lose their lives today due to radiation left by the bombs. Many critics of these treatments remember those bombings and heard of Japanese survivors being disfigured and dying horrible deaths from overexposure to nuclear radiation, not realizing that the amount of radiation the people dying from was exposed is 4 million µSv introduced throughout the body (Los Angeles Times). Radiation treatments use about 5 times this amount of radiation, using 60 to 80 Gys (Grays) of radiation to essentially disintegrate tumors (news-medical.net). Although it sounds terrifying, the radiation is reduced to one (or more) very precise beam(s), so that no radiation can irradiate any other part of the body, and once the tumor is gone, the tissue can heal. back normally. Unfortunately, many people doubt the credibility of these claims and continue to denounce the use of nuclear phenomena in medicine, because memories of nuclear bombings, although a completely different use of nuclear physics, will not be dissociated from the subject before a certain time. very long time
