Indoor and outdoor radon concentration and radon emanation from soil in Puchong area / Siti Nadiah Mohd Hafiz

Mohd Hafiz, Siti Nadiah (2010) Indoor and outdoor radon concentration and radon emanation from soil in Puchong area / Siti Nadiah Mohd Hafiz. [Student Project] (Unpublished)


The Radon (222Rn) is non-metal and progeny of radium, 226Ra in the decay series of uranium, 238U and achieved stable state at plumbum, 206Pb. It is a radioactive decay by emitting an energetic alpha particle and forming polonium, 218Po followed by others daughter product. The odorless and colorless properties of radon cause the public not have strong knowledge about the radon hazard that can cause lung cancer. Therefore, in this study indoor-outdoor concentration of radon and emanation rate has been measured by using Solid State Nuclear Track Detector. The measurement was taken from November 2009-until February 2010 at Kampung Tengah, Kampung Kenangan and Taman Puchong Perdana. The average of outdoor radon concentration for the three locations has being studied is the ranges 5.86 Bq. m"3 to 6.78 Bq. m'3. The emanation rate of radon from the soil at one location is almost the same and for the three locations, the average of emanation rate of radon from the soil is the ranges 46.00 Bq. m"2. s"1 to 185.00 Bq. m"2. s'1 . For all location, the outdoor radon concentration is shows low reading and under USEPA action limit. Thus, the three locations has been approved safe from the radon hazard
