The result of the measurements of P32 in hair and urine collected immediately after the accident showed that sufficient P32 activities had been induced in the hair by fast neutrons and in the urine by thermal neutrons to know the severity of the exposure to the individuals and to the position. From the measurement of P32 and Ca45 in bone from various anatomical parts of two patients who died 82 and 210 days after the accident, it was suggested that the distribution of the induced beta-emitters activities could prove the position and posture of the patients at the moment of exposure.}, pages = {s129--s135}, title = {Bioassay for neutron-dose estimations of three patients in the JCO criticality accident in Tokai-mura by measuring beta-ray emitters}, volume = {42}, year = {2001} }
