The gaseous 222Rn concentration at the level of clouds was estimated by using the wet scavenging model of its decay products with the observed data of environmental radiation at the ground. And the origin of the 222Rn was also discussed. The estimati

Radiocesium is an important environmental contaminant in fallout from nuclear reactor accidents and atomic weapons testing. A modified Diffusion-Sorption-Fixation (mDSF) model, based on the advection-dispersion equation, is proposed to describe the v

In response to the accident at Tokyo Electric Power Company's Fukushima Dai-ichi Nuclear Power Plant (FDNPP), vehicle-borne monitoring was used to map radiation levels for radiological protection of the public. By convention measurements from vehicle

The increase of environmental radiation dose rate during rainfall at environmental monitoring posts (MPs) was calculated by using the correlation relationship with the dose rate at the neighboring MP. The calculated dose rate agreed with the observed

We surveyed the concentration levels of Transuranium (TRU) nuclides in the effluent discharged from the Tokai Reprocessing Plant (TRP) from 1998 to 2003 for Light Water Reactor (LWR) Fuel Reprocessing. The survey was performed for upcoming the efflue

Tokai reprocessing plant (TRP) has released radionuclides such as 3H, 14C, 85Kr and 129I into the atmosphere since the start of operation in 1977. We have established the monitoring methodologies for these nuclides, to realize an appropriate and cont

A sampling system was designed to rapidly detect an unexpected release of 129I during a weekly batch-sampling of a stack gas. The system consisted mainly of a sampling unit and an iodine monitor with an NaI(T1) scintillation detector. A relationship
