Environmental Radioactivity Level Surveys

To understand the level of environmental radioactivity in prefectures, prefectural governments and the Japan Chemical Analysis Center conduct collection of environmental samples (e.g., airborne dust, fallout, inland water, soil, white rice) and analysis of them for various radionuclides including gamma-emitting nuclides, strontium-90, and cesium-137. Here you can check summary materials of the results of the surveys.
