| 摘 要： | 通过对~(137)Csγ射线穿过陶瓷体源芯、不锈钢源壳和钨钢壳后衰减规律的研究,参考用户提供的~(137)Cs稳谱源的表面γ剂量率,确定~(137)Cs稳谱源的活度。对陶瓷体源芯吸附性能进行研究,以提高~(137)Cs稳谱源γ射线输出率的一致性,最终确定~(137)Cs稳谱源的制备工艺。经使用证明,该源的γ射线输出率准确、产品一致性好,已应用于岩性密度测井仪测井,可实现~(137)Cs稳谱源的国产化。

| Abstract: | The attenuation laws of the Cesium -137 γ-ray penetrating the ceramic core.stain- less steel and tungsten steel were studied. The radioactivity of the 137TCs stabilizer source was determined through the surface dose rate of 137Cs stabilizer sources. In addition, the adsorption properties of the ceramic core were studied to improve the stability of the output rate, and established a production line. The application results showed that the output rate of-ray source was accurate and was of a good consistency. At present, the source had been used in logging lithology, and achieved the realization of domestic product. |
