The study aims to investigate the concentration of radon - a gas form of radioactive substance emitted from soil, cement, concrete, etc, and may couse cancer to building occupants - in newly-constructed apartment buildings. Both the field measurement and the laboratory experiment were conducted.The measurement from 14 new houses indicates that a RC house produces the most radon emission(4.75 pCi/l max.), followed by a PC house and a wood-structured model house. The laboratory experiment, reveals that, among the various building materials, a Gypsum board partition has the highest radon concentration of 68.1 pCi/l, followed by a RC wall of 34.0 pCi/l.A PC wall shows, as in the field measurement, negligible radon concentration. |
