| Abstract: | This paper report s the conclusion of measuring natural radiation nuclei 232Th and 238U in Al specimen , that is the 232Th content range f rom 2.3 ×10 - 3 to 7.0 ×10 - 3Bq/ g , the 238U from 0.36 ×10 - 3 to 0.55 ×10 - 3Bq/ g. At same time , the correction of shielding effect of environmental radiation is made as measuring. The result s show that the method of shielding correction is right . |
