Investigations of Outdoor and Indoor <sup>222</sup>Rn Concentrations Level in Academic Building at Universiti Malaysia Kelantan Jeli Campus
Materials Science Forum(2017)
摘要
Radon (222Rn) is radioactive gas emanates from soil, rock sand and enter the building through cracks, construction joint, gas in suspended floors and also from the building materials itself. 222Rn gas in high concentrations is hazardous as it can affect the human organ and tissues due to the emission of alpha particles. This study aims to determine the outdoor and indoor 222Rn concentrations in academic building, Universiti Malaysia Kelantan (UMK) Jeli Campus as well as to identify any possible factors influenced the gas progenies. Radon Sentinel 1030 was placed in open space between the lecturer’s rooms and inside closed room (Lecture Hall 4) on the first floor of the building for data collections. The total of 224 data of 222Rn concentrations reading has been collected for outdoor and indoor spaces with 0.5 hours time interval. The outdoor and indoor 222Rn concentrations were found in ranges between 0.23 pCi/L to 0.48 pCi/L and 0.73 pCi/L to 1.13 pCi/L, respectively.
