︎︎Radiation shielding material (Anti-Sievert®)

  The dissemination of radioactive material in the accident at Fukushima Daiichi Nuclear Power Plant will have an ongoing impact on the environment and ecosystem.  We believe that convergence requires a very long period of time and much efforts.

  Although various on-site responses are required, we considered radiation shielding materials to be great desire for the function of shielding against radiation.  We propose some radiation shielding materials.



︎︎Anti-Sievert® Nuclear Bomb Shelter

  The concrete using radiation shielding material (Anti-Sievert®) shows 2 to 3 times the normal compressive strength. Considering the utilization of this concrete as a nuclear shelter, we conducted intensity simulation. As a result, it showed that with a distance of about 1 km against a nuclear explosion of about 50 kiloton it can withstand sufficiently.
