Radon is a colorless and odorless gas. According to epidemiological survey, radon is, second to smoking, the main cause of lung cancer. Prolonged exposure to high concentrations of radon may lead to lung cancer. However, this issue is often neglected as it generally takes 15 to 40 years of prolonged radon exposure for the pathological changes to take place. The World Health Organization published WHO Handbook on Indoor Radon in 2009 to raise worldwide attention. The way to prevent radon pollution is either blocking or diluting it. In Taiwan, the Chinese National Standard CNS 6873 A 3118 states the procedures for the determination of indoor ventilation rate. Basically, CNS 6873 uses CO2 as the tracer gas to measure the ventilation rates. Therefore, in order to evaluate indoor radon pollution sources and the ventilation rates, radon was used as the tracer gas in this study.The first stage of this study focused on measuring the potential indoor radon sources and discussed the radon emission rates in detail. The results showed that the element in the test building with the highest radon emission rate was the wall, followed by the ceiling and the floor. The second stage of this study used radon as the tracer gas to measure the indoor pollution emission and ventilation rates. Well-mixed model was applied as the physical model to carry out regression analysis to obtain the steady-state concentration and emission rates of the target space. The steady-state concentration ranged 264.3~373.1 Bq/m3 in summer and 392.2~466.8 Bq/m3 in winter; The radon emission rate was 4.066~11.42 kBq/hr in summer and between 5.630~10.79 kBq/hr in winter.The result shows the radon concentration for the target space is 2

In recent years, with the rapid industrial and commercial development and large concentration of population, making the water demand increasingly. Because of insufficient use of surface water, the type of seasonal rainfall, topography special, short steep rivers, water is not easy to grasp, resulting in a large number of dug wells. Due to the low cost of groundwater, water quality and quantity is more stable than the surface water, resulting in a large number of cut excessive pumping phenomenon. The nature replenishment slowly can not keep up Drilling wells, then water environment caused irreparable harm. Pay attention to illegal wells, investigation of wells difficulty and pumping groundwater will cause subsidence and salinization and water resources in coastal areas lead to soil salinization, and so the situation must immediately investigate and evaluate the necessity for sealing and fill wells. In this study, the water quality is estimated by means of empirical method, measure method of water flow in wells and the electricity consumption method for each industries of pumping water to develop the land subsidence control program in different regions. At the same time, discuss the reduced and sunk amount of the water table to provide follow-up study of academic. After the analysis of research that there is no inventory of the six districts of Tainan industrial wells. Compare the divergence of industry of quantity come from the Taiwan Water Corporation and emissions of water of Environmental Protection Agency of Tainan City Government, there were kind of three industry the more emissions of water than quantity we found: Community sewage systems, buildings, and the industry of non-industrial areas. Than we remove the possibility of pumping well of the first two after researching, but suspected of pumping wells of 8 industry include the Dyeing, electroplating, and department stores, while it need the water large quantity and no reason to prove the different of quantity. The result for investigating the wells in agriculture that as follows: there is 7 wells and estimated amount of water is 7,900 tons/year in Eastern District; 159 wells and estimated amount of water is 172,300 tons/year in Southern District; 33 wells and estimated amount of water is 62,100 tons/year in Annan District, then there is no well in North Distric and Central Western District, Anping District. Assess the necessity for wells sealing and fill through the environmental score factor. The six Distric of Tainan are part of control area of groundwater, although the government initiate powerfully, the populaces.
