Nuclear energy and nuclear weapons have been historically connected in Japan and elsewhere. Japan’s nuclear energy program, particularly, its breeder reactor program and used fuel reprocessing, has been directly linked to its national security. This chapter explores how nuclear energy became an important foundation of Japan’s national security and...

... Computer modelling carried out by us and published on the internet and elsewhere suggest that the plumes from the catastrophe have travelled south over the highly populated areas in and near Tokyo. Dose rates have been published for these areas and from these dose rates it can be assumed that significant exposures have occurred. From Table 4 and Fig. 3 we can assume that the exposures are of the order of 1 μSv/h with associated contamination levels. Therefore the methods employed for the 100km area may be extended to the 200km area. The population is, however much greater at 7,874,600. The results are given in Table 6. ...

... so radioactive that when I sent them for high resolution gamma spectrometry, the lab I sent them to complained that it was illegal to post them though the UK mailing system. A low resolution gamma spectrum of a car engine filter from Tokyo is shown in Fig. 2 where the Caesium-134 peaks are identified. An autoradiograph of a car filter is shown in Fig. 3 below (obtained by Marco ...

Nuclear power industry could be truly sustainable only under the condition of the Treaty on the Non- Proliferation of Nuclear Weapons. Thus, the issue of nuclear materials illicit diversion is crucial. One possible way to increase the resistance of the nuclear system to proliferation could be the increase of inherent security of nuclear materials u...
