| Research Abstract |
In patients subjected to Atomic bomb there was no evidence of introduction of radioactive material. A much more palpable danger would exist from the ingestion or inhalation of radioactive material to increase cancer risks.
Here, we studied the preserved body cells of Nagasaki A-bombed victims in 1945, and became the first one to prove that plutonium (Pu) is continuing to emit radiations after more than 70 years in human body since the A-bomb attack.
Alpha particles emitted from the specimen such as lung, liver, bone etc. were detected by autoradiography. The frequency distribution of alpha-particle track lengths of A-bomb cases was consistent with the pattern of alpha-particles emitted from 239, 240Pu, different from that of controls. The internal radioactivity of A-bomb cases was higher than that of controls and relevant for factors of shielding and death time. Our achievement will pave the way to study 'internal A-bombed' and has contributed a lot to support the Hibakusya's insistence.
