Research Abstract

The purpose of the present research is the development of a numerical simulation model for long range transport of atmospheric pollutants including radioactive substances. A numerical simulation model has been constructed for naturally occurring radioactive rare gas, radon-222. A local-scale (80kmX80km) simulation model around Nagoya and a regional-scale one (4,000kmX4,000km) over eastern Asia compose the model. To compare calculational results with measurements, continuous measurements of atmospheric radon have been carried out at Nagoya, Kanazawa and Fukui. The results of calculation in each four season coincided fairly well with measured one at Nagoya. In the present work, we have also started to develop a dynamic model to simulate better the transport of radon.
The present regional-scale model has been applied to the simulation of long-range transport of tritium in water vapor over eastern Asia. The transport of tritium was calculated for about two weeks in November, 1978, when the tritium concentration in Japan was much higher than the low level at present and there are abundant literature of environmental tritium in China. The calculated results agreed within the factor of two with the observed one. Thus the present research have provided a preliminary stage simulation model for long range transport of tritium, but there are many problems to be solved in the future.
