Knowledge of radioactivity levels and the behavior of radionuclides in the environment are important in terms of radiation protection. Artificial radionuclides are already distributed in the environment as products of atmospheric nuclear tests and nuclear power plants. However, naturally occurring radioactive material (NORM) and technologically enhanced NORM (TENORM) associated with consumer goods have also become of concern. Radon, for example, represents a large contribution to natural radiation. The Japan Chemical Analysis Center (JCAC) has carried out a series of nationwide surveys under the auspices of the Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan. This communication presents an outline of the environmental radioactivity survey and its implementation by the JCAC.
