Studies of Radioactivity Produced by the Hiroshima Atomic Bomb: 2. Measurements of Fallout Radioactivity

Atomic Batteries: Energy from Radioactivity

With alternate, sustainable, natural sources of energy being sought after, there is new interest in energy from radioactivity, including natural and waste radioactive materials. A study of various atomic batteries is presented with perspectives of development and comparisons of performance parameters and cost. We discuss radioisotope thermal generators, indirect conversion batteries, direct con...

Atomic bomb injuries among survivors in Hiroshima.

Leukemia in Hiroshima atomic bomb survivors.

A CAUSAL RELATION between radiation and leukemia has been well demonstrated.112 The reported cases of leukemia in people exposed to radium, 1.’I 4 1 occupational x-ray,’ I therapeutic x-ray to the thyroid region in childhood’92#{176} and possibly in utero diagnostic x-ray,2’ have been few in number. Estimates of the increased risk associated with exposure of man to radiation depend heavily upon...

Measurements of (60)Co in massive steel samples exposed to the Hiroshima atomic bomb explosion.

To study discrepancies in retrospective Hiroshima dosimetry, the specific activity of (60)Co in 16 steel samples from Hiroshima was measured using gamma-ray spectrometry in underground laboratories. There is general agreement between these new activity measurements and the specific activities derived from previously calculated dose values on the one hand and former measurements of samples gathe...

High incidence of meningioma among Hiroshima atomic bomb survivors.

Since the atomic bomb explosions in Hiroshima and Nagasaki, high incidences of leukemia, thyroid cancer and other tumors have been reported as atomic bomb-induced tumors. We investigated the incidence of meningioma among Hiroshima atomic bomb survivors. Sixty-eight patients surgically treated for meningioma who had been within 2.0 km of the hypocenter of the explosion were identified. Six hundr...
