| Abstract: | 226Ra.232Th.40K contents in main new building materials in Hami Prefecture were determined and analysed by the radiochemical method. The results show that the range of average wine of inside and outside radiation coefficient are 0. 02-0. 26 and 0. 03-0. 06,respectively. Its effective dose equivalent to poputation is 0. 06-0. 96 m Sr a-1,which is obviously under the normal background level of indoor Y radiation and decay of Radon. |
