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

A simple and reliable sampling system for 3H and 14C in airborne release from nuclear facilities was designed. The sampling system can collect 3H and 14C simultaneously with a condensation technique using a commercially available cold trap equipment

To establish a practical method for monitoring 129I concentration in airborne release from the Tokai reprocessing plant, the 129I collecting performance of sampling media used was tested by in situ experiments. The results indicated that the combined

Fuel reprocessing plant is one of the most important sources of anthropogenic (14)C in the environment. A method was developed to determine the amount and chemical composition of airborne (14)C release from the Tokai reprocessing plant, Japan. Efflue

A method using a system with two sampling units was proposed to determine the chemical forms of tritium (3H) released into the atmosphere from the Tokai Reprocessing Plant (TRP). The main advantage of the method is that no carrier gas is required for

The effects of incorporating tritiated water into a 14C-sampling system in sample preparation and 14C activity measurement by liquid scintillation counting were investigated. Experiments derived the limit of water content in the prepared sample, and

An autoradiographical method using an imaging plate (IP) was developed to identify rapidly the density of plutonium (Pu) particles on filter samples. Photostimulated luminescence (PSL) signals were obtained by exposing IPs to filter samples collectin
