Description

The neutron dose reassessment of atomic bomb at Hiroshima was done by using residual activity of 152Eu of granite rock specimen taken out from 41.5cm depth position inside the Motoyasu bridge pillar. The neutron dose (tissue Kerma in air) at a point of 132m of SSW direction from the hypocenter was experimentally evaluated to be 15.5Gy. The obtained value shows that it is needed to argue and include the anisotropic performance of Hiroshima atomic bomb warhead. After the correction of anisotropic effect of warhead, the source yield of Hiroshima atomic bomb is estimated to be 17.7Kt by combining the measured value obtained here with DS86 calculated value
