METHOD FOR PREDICTING INDOOR VENTILATIORY VOLUME BASED ON RADON RADIATION AMOUNT OF CONSTRUCTION MATERIAL AND APPARATUS FOR REDUCING RADON AUTOMATICALLY USING THE SAME METHOD

摘要

The present invention relates to a method for predicting an indoor ventilation rate based on a radon emission amount of construction material and an apparatus for automatically reducing radon using the same. The method comprises: a step of substituting a radon emission amount of construction materials in a building in a mathematical prediction model which represents a relationship between the radon emission amount of the construction materials and the minimum indoor ventilation rate of a building; and a step of calculating the minimum indoor ventilation rate to maintain an allowable cumulative exposure effective dose when the indoor air is exposed to radon emitted from the construction materials, from the mathematical prediction model. Therefore, the present invention is capable of predicting the indoor ventilation rate which can eliminate harmful influences on the health of residents due to radon emitted from the construction materials using the minimum indoor ventilation rate.
