| Research Abstract |
Analysis of atmospheric transport model is essential to understand and solve atmospheric environment problems. The validation of the model is important to make the model simulation reliable. We measured atmospheric radon-222 concentration near the surface with high-sensitivity radon monitor, clarifying seasonal variation and its inter-annual difference. Additionally, We evaluated the performance of a long-range atmospheric radon transport model. As a result of comparison between measuredconcentrations and calculated concentrations, 70 % of the calculated values werewithin a factor of 2 of the measured values. It indicated that the uncertainty was estimated to be a factor of 2.
