Database
Measured air dose rate data, i.e. the amount of radiation per unit time in the air (Air absorbed dose rates[nGy/h], or ambient dose equivalent rate[μSv/h]). The air dose rate is continuously observed around the nuclear facilities to detect abnormality including radioactive substances leakage.
In order to confirm the condition in the depth distribution of radioactive cesium comprehensively mainly within a 80 km radius of the Fukushima Dai-ichi NPP, we collected soil samples at various depths using a scraper plate which is the standard method to measure radioactive nuclides in soil profiles employed at IAEA and researched the depth distribution of radioactive cesium.
Measured data of radioactive substances released to the environment by Fukushima Daiichi NPP accident in seawater.
Measured data of radioactive substances released to the environment by Fukushima Daiichi NPP accident in marine soil.
Measured data of radioactive concentration deposited on the surface soil after TEPCO's FDNPP accident.
Measured data of radioactive substances released to the environment by Fukushima Daiichi NPP accident including ground deposition, radioactive concentration of soil sample and environmental sample, and radioactive substance depth distribution.
