Radioisotopes of caesium require special precautions: the improper handling of caesium-137 gamma ray sources can lead to release of this radioisotope and radiation injuries.
之后将来自铯枪的离子射向目标轮,产生负离子化碳原子。
Ions from a cesium gun are then fired at the target wheel, producing negatively ionized carbon atoms.
VK-WSX is a non-cesium catalyst; yet it can operate effectively at temperatures as low as 370°C/700°F, enabling very high conversion rates to be reached.
因此铯原子就可以用作一种节拍器来保持高度精确的时间。
For this reason, the cesium atom can be used as a metronome with which to keep extraordinarily precise time.
污染地区居民吸收的放射性铯含量自1995年以来进行了大规模测量。
Since 1995, mass measurements of absorbed radio-caesium content for inhabitants of the contaminated areas have been conducted.
目标是技术性(展示铯原子钟)和科学性并存。
The objectives are both technological(demonstration of a caesium atomic clock) and scientific.
因为氯化铯被宣称是通过升高肿瘤细胞的PH值而起作用,它在治疗上的应用已被称为“高PH值疗法”。
Since cesium chloride is claimed to work by raising the pH of the tumor cells, its use in therapy has been called"high pH therapy.".
In 1968, Louis Essen, the inventor of the caesium atomic clock, and G. M. R. Winkler both independently proposed that steps should be of 1 second only.
It can be produced through the following reaction: Cs2CO3+ CO2+ H2O→ 2 CsHCO3 The compound can be used for synthesizing caesium salts, but less common than caesium carbonate.
比基尼岛本身被宣布不适合人类居住,而其他三个环礁的放射性核素浓度也很高--主要是镅、铯和钚。
Bikini Island itself was declared unsafe for human habitation, while the three other atolls had significant radionuclide concentrations- mainly americium, cesium, and plutonium.
The Maišiagala repository, since 1963 operated by the Soviet military, was closed in 1988, but high-risk radioactive sources, including caesium, still remain buried at the site.
刚果放射性材料专家表示,近六年来,国家安全机关已在金沙萨市区和周边没收50多箱铀和铯。
According to Congolese experts on radioactive materials, organs of State security have, during the past six years, confiscated over 50 cases containing uranium or cesium in and around Kinshasa.
关于曝露于某些内部放射体对生物的影响评估,鉴于福岛事故,印度支持针对铯和碘开展类似评估的提议。
Regarding the evaluations of the biological effects of exposure to selected internal emitters, India supported, in light of the Fukushima accident, the proposal to conduct similar evaluations for caesium and iodine.
近年来,研究人员致力于测试不同的配方,以获得更好的效率,例如在卤化铅-钙钛矿中添加铷和铯离子。
In recent years, researchers have focused on testing different recipes to achieve better efficiencies, such as adding rubidium and cesium cations to lead-halide perovskites.
在核电站发生紧急情况期间,放射性材料可能会释放到环境中,影响人的健康的放射性核素主要是碘和铯。
Radioactive material may be released into the environment during an emergency at a nuclear power plant, the radionuclides of main concern to human health being iodine and caesium.
