放射性

Ironically it was Irène Joliot-Curie, the daughter of Marie and Pierre Curie who first isolated polonium in 1898, who was the first to die because of exposure to it.

具有讽刺意味的是这个死者就是1898年首次分离出钋元素的居里夫妇的大女儿伊伦-约里奥-居里。她是因为长期接触这种放射性元素而死亡的。

Results The choroid plexus, hypophysis, area postrema and pineal body, namely, circumventricular organs and ependyma as well as pia mater layers were stained by the HRP reaction products.The HRP reaction products were observed in the tissue space of membrane mucosa nasi, around the fila olfactoria and venules, and within the venules under the light microscopy and electron microscopy, also. Scintillation count showed that the radioactivity of the CVOs was higher than that of the background. The radioautography showed that the scattered grains of silver existed within the cells of neurocyte layer also.

结果 在脑室周围器官及脑室周围室管膜、软脑膜层有HRP反应产物的聚集，在鼻中隔的鼻粘膜下组织间隙、嗅丝周围间隙及静脉周围和管腔内也可见到HRP反应产物；液闪计数显示，大白鼠的脉络丛、脑垂体、最后区、松果体等脑室周围器官放射性活度明显高于本底；放射自显影显示大白鼠脑组织神经层细胞内有散在分布的银颗粒。

Then she found that pitchblende was more radioactive than uranium by itself.

玛丽注意到钍元素也是具有放射性的。

In reality the proportion of the hypothetical element was far lower and it took several years to show unequivocally that ''.'pitchblende'.

实际上这种假设中的元素的浓度要小得多，我们花了几年时间才明确无误地证明沥青铀矿物质中至少含有一种高放射性物质，在化学意义上这就是一种新元素。

In reality the proportion of the hypothetical element was far lower and it took several years to show unequivocally that pitchblende contains at least one highly-radioactive material which is a new element in the sense that chemistry attaches to the term.

实际上这种假设中的元素的浓度要小得多，我们花了几年时间才明确无误地证明沥青铀矿物质中至少含有一种高放射性物质，在化学意义上这就是一种新元素。

We found that pitchblende contains at least two radioactive materials, one of which, accompanying bismuth, has been given the name polonium , while the other, paired with barium, has been called radium.

我们发现沥青铀矿物中至少含有两种放射性物质：与铋伴生的命名为钋，与钡伴生的命名为镭。

In this paper, statins pleiotropism at radiation-induced lung injury, lung tumor, pulmonary hypertension, pulmonary fibrosis, acute lung injury, chronic lung injury and other lung diseases will be reviewed.

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
