Study on Assay Methods for Irradiated Traditional Chinese Medicinal Materials with Thermoluminscece Analysis
The verification method and standard were studied to be used for identification whether the traditional Chinese medicinal materials was irradiatedated or not with thermoluminescent dosimeter(TLD).After the silicate was isolated from the sample,its peak area integral G1 of thermoluminescent curve was measured by TLD.Then the silicate was irradiated by at dose of 1.0 kGy,and its peak area integral G2 of thermoluminescent curve was also measured.The ratio of G1/G2 was calculated as criteria whether the sample had already irradiated or not.When G1/G2≥0.10,the sample was verified as having been irradiated,while G1/G2＜0.10,the sample was verified as having not been irradiated.
