Some new work on the Cherenkov counting technique and rapid radiochemical analysis has been published. 契连可夫计数技术以及快速放化分析方面也有新的工作发表。
The practical technique was provided for the radiochemical synthesis and entiomeric purity of 6 [ 18 F ]fluoro L DOPA. 为 6 [1 8F] L 多巴的放射化学合成及其对映纯度的测定提供了可靠的技术
The specific activities of these productsare 10ci/mmole and their radiochemical purity,more than 98%. 经鉴定紫外吸收光谱性质与标准样品一致,比放射性达10居里/毫克分子,放化纯度在98%25以上。
NGA was labeled directly with Na99mTcO4. The radiochemical purity of 99mTc-NGA was over 90%. 用直接法制备99mTc－NGA，其放化纯大于90%25，且室温下 可稳定6h以上，符合显像要求。
Progress in radiochemical analyses in 40 years since CIRP's founding is described in this paper. 介绍了中国辐射防护研究院建院40年来放射化学分析工作的进展。
At present the enzyme reagents method and radiochemical enzymatic assay were commonly used to detect carnitine. 本研究经详细的方法学研究，建立了精浆中游离肉毒碱的柱前紫外衍生高效液相色谱测定方法。
