Outline of Final Research Achievements

Tritium, when it is released to air, is said to be converted to tritiated water. We prepared a 1 m stainless double-walled cell and prepared a highly concentrated tritiated water that is necessary for the spectroscopic measurement. The near-infrared laser spectroscopy technique was applied to obtain the spectral information and assigned spectral lines based on the quantum chemical calculations. Two diode lasers were used to cover the two wavelength region about 1.38 micron and 1.45 micron. Including the information of the change in pressure, self-radiolysis reaction of the tritiated water due to the tritium's radioactivity was investigated.
