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...

... that is the origin of the genetic effects which are the cause of the illnesses. One other way is when the exposure is to micron sized particles, so-called hot particles (but also not-so-hot particles). These were detected after Fukushima in Tokyo, and as far away as Hawaii and California. The ionization density near such particles is very great. Fig. 1 shows a graph of the concentration of Uranium after Fukushima by distance from Japan. This shows the presence of Uranium particles in air, being breathed in. But these particles can be so small they effectively act as a gas and can pass though the skin. An analogy would be comparing sitting in front of a warm coal fire and absorbing X ...

... period 166 d. Procedures as in Figure 1 Worst Case Scenario Because of the way in which ocean currents and atmospheric air movements operate, I do not think that there will be any measurable effect in the Southern hemisphere, and the concentrations in Europe of the Fukushima material (which we monitored and even measured) were too low to cause any effects. Unlike the atmospheric test fallout, Fukushima is mostly a local affair. ...

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...
