|Title:||Evaluation of radon exhalation rate from granite stone|
Shalkouhi, P Jafari
|Abstract:||This study evaluates radon exhalation rate from 10 different granite stones, used for building construction in Iran.Radon exhalation rate ranged from non-detectable to 0.6 Bq m<sup>-2</sup> h<sup>-1</sup>. Six samples had exhalation rate above detectable level. Asignificant statistical relationship between radon exhalation rate with <sup>226</sup>Ra and <sup>232</sup>Th indicated that <sup>226</sup>Ra and <sup>232</sup>Th wereresponsible for radon exhalation from granite stones.|
