It is said that the natural radiation we are exposed to from the ground in our daily lives here in Japan is about 1mSv/yr. But what about people who work at a nuclear power plant? They are classified as people whose work involves radiation, but they are only exposed to the same 1mSv/yr. To show you just how little exposure that is, let’s compare it to several other cases of radiation exposure.

Here we present an animated image of the “five wall” structure of pellets, fuel-cladding canisters, nuclear reactor pressure vessels, nuclear reactor containment vessels and the nuclear reactor building used for effectively encasing radioactive material, and easy to understand explanations of ISOE’s objectives, organization, participating members, database, symposia and reports.
