adj.[化] 放射化學(xué)的

n.已含放射性同位素的化學(xué)物質(zhì)

Some new work on the Cherenkov counting technique and rapid radiochemical analysis has been published. 契連可夫計(jì)數(shù)技術(shù)以及快速放化分析方面也有新的工作發(fā)表。

The practical technique was provided for the radiochemical synthesis and entiomeric purity of 6 [ 18 F ]fluoro L DOPA. 為 6 [1 8F] L 多巴的放射化學(xué)合成及其對(duì)映純度的測(cè)定提供了可靠的技術(shù)

The specific activities of these productsare 10ci/mmole and their radiochemical purity,more than 98%. 經(jīng)鑒定紫外吸收光譜性質(zhì)與標(biāo)準(zhǔn)樣品一致,比放射性達(dá)10居里/毫克分子,放化純度在98%25以上。

NGA was labeled directly with Na99mTcO4. The radiochemical purity of 99mTc-NGA was over 90%. 用直接法制備99mTc－NGA，其放化純大于90%25，且室溫下 可穩(wěn)定6h以上，符合顯像要求。

Progress in radiochemical analyses in 40 years since CIRP's founding is described in this paper. 介紹了中國(guó)輻射防護(hù)研究院建院40年來(lái)放射化學(xué)分析工作的進(jìn)展。

At present the enzyme reagents method and radiochemical enzymatic assay were commonly used to detect carnitine. 本研究經(jīng)詳細(xì)的方法學(xué)研究，建立了精漿中游離肉毒堿的柱前紫外衍生高效液相色譜測(cè)定方法。
