Abstract

Specific activites of natural (40K, 226Ra and 40Th) and anthropogenic (137Cs) radionuclides in 30 glutinous rice samples bought from some local retailers and department stores in Songkhla Province have been measured and analyzed. Experiment results were carried out by using a high-purity germanium (HPGe) detector and gamma spectrometry analysis system at Radiation Laboratory in Thailand Institute of Nuclear Technology (Public Organization) (TINT). The results show that the specific activities of 40K, 226Ra, 232Th and 137Cs in 30 glutinous rice samples ranged from < 592.21 – 896.36, < 3.73 – 11.92, < 2.49 – 7.84 and < 1.54 – < 2.35 Bq/kg respectively, with mean values of 683.13 ± 33.61, 6.09 ± 1.78, 4.20 ± 1.52 and < 1.92 ± 0.21 Bq/kg respectively. Furthermore, some related radioactive hazard indices and the excess lifetime cancer risk (ELCR) value were also evaluated and found in the safety values. Moreover, all the results were compared with Office of Atoms for Peace (OAP) data, research data in Thailand, international studies and some recommended values.

糯米(Oryza sativa var. glu-tinosa)本底放射性及相关放射性危害指标评价

测量和分析了从宋卡省一些当地零售商和百货商店购买的30个糯米样品中天然(40K、226Ra和40)和人为(137Cs)放射性核素的特定活性。实验结果由泰国核技术研究所(公共组织)(TINT)辐射实验室的高纯度锗(HPGe)探测器和伽马能谱分析系统进行。结果表明，30份粳米样品中40K、226Ra、232Th和137Cs的比活性范围分别为< 592.21 ~ 896.36、< 3.73 ~ 11.92、< 2.49 ~ 7.84和< 1.54 ~ < 2.35 Bq/kg，平均值分别为683.13±33.61、6.09±1.78、4.20±1.52和< 1.92±0.21 Bq/kg。此外，还评估了相关的放射性危害指标和过量终身致癌风险(ELCR)值。此外，所有结果都与原子和平办公室(OAP)的数据、泰国的研究数据、国际研究和一些推荐值进行了比较。
