放射性

The evolution of radioactivity and poisonousness of the products after nuclear explosion is very important for safety and environmental protection.

核爆炸后产物放射性和毒性及其随时间的变化是有关安全保障和环境保护的主要问题。

In 1898, they believed that something in nature which gave out radioactivity .

1898年，他们相信自然界中存在着具有放射性的某种东西。

There was in nature another element which sent out radioactivity.

在自然界里存在着另一种具有放射性的元素。

Methods Using the excellent radioautography technigue, the diffusion, particle size and inhalable fraction of radioactive plutonium aerosols in the accident site were analyzed.

使用优异的放射自显影技术来分析放射性气溶胶在事故现场的扩散和粒径大小，以及可吸入的组分。

Polyethylene glycol (MW6000 35%)-Ca〓(40mmol/l) system was applied to research on the fusion of nuclei and anucleated protoplasts which were deactivated by ultraviolet rays. The fusion process was verified by -dCTP radioisotope tracing with radioautography.

选择PEG6000促融，40mmol/1Ca〓进行了K氏酵母细胞核与His酵母经紫外线灭活的无核原生质体融合的研究，利用放射性同位素dCTP的示踪结合放射自显影技术，对融合进行检测，证实了融合的确实发生。

If the claims of this testimony are correct, it would be consistent with the radiocarbon dating of the shroud.

如果这个见证的声称是真实的话，那么裹尸布的放射性碳年代测定将会相互一致。

One obvious flaw in this technique is that we don't really know the level of radiocarbon concentration acquired by an organism which lived before such recorded history.

一个明显的缺陷，这种技术是，我们不知道他们的水平放射性浓度收购的一个生物体生活在这样的历史记载。

The fact is, radiocarbon concentrations have been proven to fluctuate.

事实是，放射性浓度已证实出现波动。

Radiocarbon dating is a commonly used method to determine the age of archaeological finds.

放射性碳测年法是一种常用的确定年龄出土文物。

The material in this beach has been dated by radiocarbon.

这个海滩上的物质经过放射性碳测定。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
