中文摘要 | 本研究探討以柳杉、胡桃木、相思樹進行不同木材裝修條件對室內氡濃度之影響,空間尺寸為3100 mm(長)× 1680 mm(寬)× 2400 mm(高),以花崗岩為氡發生源,各條件之監測期為216 小時。結果顯示鋪設實木地板即可顯著降低20.2%氡濃度,裝修地板及壁板後可降低氡濃度26.1%,其中壁板裝修量40%及80%之間差異不大。裝修材為未塗裝及塗裝者,其空間氡濃度降低量分別為17.0%及31.1%,以塗裝材之裝修效果為優。在未塗裝之裝修條件下,鋪設地板再裝修壁板時,可進一步降低氡濃度。柳杉裝修材經塗裝後,其空間氡濃度可降低38.2%,優於胡桃木及相思樹,未塗裝者則以胡桃木之22.9%為佳。以不同條件裝修後之空間,其氡濃度變化可以非線性之廻歸方程式進行估計。 |
英文摘要 | Effect of various furnishing conditions using Japanese cedar, walnut, and acacia wood materials on the radon concentration in an indoor space was investigated in this study. Sizes of the test room are 3100 (length) × 1680 (width) × 2400 mm (height) with granites as the radon source. Monitoring duration for each furnishing condition is 216 hrs. The experimental results indicate an average 20.2% reduction in radon concentration in a room installed with wood floorings. The radon concentration is dropped 26.1% in a room space furnished with both wood flooring and wall, but minor difference is found between 40% and 80% of the wall decorated with wood strips. There are respectively 17.0% and 31.1% in radon concentration reduction for the room installed with uncoated or coated wood furnishing materials showing better performance of coated wood furnishing materials. For the uncoated wood furnishing materials, a further reduction in radon concentration is achieved by installing wood flooring in addition to wood walls. Radon concentration can be reduced by 38.2% when the room decorated with coated Japanese cedar furnishing materials, which is better those by that using coated walnut or acacia wood. For the uncoated furnishing materials, larger radon concentration reduction is found for a room installed with walnut wood. A non-linear regression equation can be used to estimate the radon concentration changes in a space installed with various furnishing conditions. |
