Among the substances in third-hand smoke are hydrogen cyanide, used in chemical weapons; butane, which is used in lighter fluid; toluene, found in paint thinners; arsenic; lead; carbon monoxide; and even polonium-210, the highly radioactive carcinogen that was used to murder former Russian spy Alexander V.

三手烟中的物资包括用于制造化学武器的氢氰化物，轻质石油的丁烷，涂料稀释剂中的甲苯，砷，铅，一氧化碳，甚至还有谋杀了前苏联间谍亚历山大利维尼柯的极具放射性致癌物资钋210，三手烟中11种组成物质都是高致癌物资。

People through nuclear reactions, have been synthesized 17 kinds of atomic number greater than 92 of the transuranic elements, and thousands of The new kinds of radioactive nuclides, and by high-energy and ultra-high energy-ray beam and the interaction of atomic nuclei and found hundreds of kinds of short-lived particles, namely, baryon, meson, lepton, and particle resonance states of these particles has led to a new field of study - the birth of particle physics since the age of .70, nuclear physics has entered a deep development and wide application of new, more mature stage, on the one hand the development of particle acceleration and detection techniques, expanding people's research in nuclear means, the other hand, nuclear technology to serve the national economy, for example, for the development and utilization of nuclear energy to provide more accurate nuclear data; the use of isotope tracer technique diagnosis and treatment of disease; the use of radiation and irradiation preservation of food, irradiation breeding .

人们通过核反应，已经人工合成了17种原子序数大于92的超铀元素和上千种新的放射性核素，并且通过高能和超高能射线束和原子核的相互作用，发现了上百种短寿命粒子、即重子、介子、轻子和共振态粒子，对这些粒子的研究导致了一门新学科——粒子物理学的诞生。70年代以来，核物理进入了纵深发展和广泛应用的新的更成熟的阶段，一方面发展粒子的加速技术和探测技术，扩充人们研究原子核的手段，另一方面将核技术服务于国民经济中，例如，为核能的开发利用提供更为准确的核数据；利用同位素示踪技术诊断和治疗疾病；利用射线及辐照技术保存食品、辐照育种等。

The main toxic reaction to confined doses included grade Ⅱ/Ⅲ leucopenia (42.9%) and trach-eitis (36.1%).

主要剂量限制性毒副反应为Ⅱ、Ⅲ级白细胞下降(42.9%)和放射性气管炎(36.1%)。

An agent, such as ultraviolet light or a radioactive element, that can induce or increase the frequency of mutation in an organism.

诱变剂有机体中的一种可诱发或者增加突变的次数的因子，如紫外线或放射性元素

Generally, the paleo-dose is obtained by linear extrapolation in regeneration or additional irradiation method.

古剂量则是在实验室内经放射性源的人工辐照模拟自然界的ESR信号增长情况获得的。

What is even more incredible, is that one of the authors of the fictional letter, Lippmann, was the one to read to French Academy of Sciences the first paper written by Madame Curie on her discoveries of radioactivity.

更难以置信的是这封作伪证的信的作者之一，李普曼，竟是法国科学院阅读过居里夫人发现放射性第一篇论文的读者之一。

Thus, the Gamma-ray spectral logging apparatus in this paper will become a tool of ad vanced logging in ore miningg industry and as wellas the coal industry. The study is advanced and practical.

结果表明，研制的γ能谱测井仪，将为我国新形势下的有关非油气地质工作，如固体矿产勘探、煤田地质、水文工程地质及环境地质等等，提供一种先进的测井手段，使我国应用于小口径的放射性γ能谱测井技术能跻身于世界前列，研究成果是先进实用的，具有经济、社会和环境效益，可在我国推广应用。

The non-radioactive long afterglow phosphor is a kind of environmental application material which has been used in more and more extensive fields such as light sources in emergency, luminous paint and so on.

非放射性长余辉发光材料是一类环保型的应用材料，作为美化和清洁光源在紧急突发事件的照明设施、夜光油漆等众多领域得到越来越广泛的应用。

At this time Madame Curie's husband Pierre Curie joined with her in search of the unknown radiation.

这时，居里夫人的丈夫皮埃尔·居里也和她一起寻找这未知的放射性物质。

Article 24 Units that cause environmental pollution and other public hazards shall incorporate the work of environmental protection into their plans and establish a responsibility system for environmental protection, and must adopt effective measures to prevent and control the pollution and harms caused to the environment by waste gas, waste water, waste residues, dust, malodorous gases, radioactive substances, noise, vibration and electromagnetic radiation generated in the course of production, construction or other activities.

第二十四条产生环境污染和其他公害的单位，必须把环境保护工作纳入计划，建立环境保护责任制度；采取有效措施，防治在生产建设或者其他活动中产生的废气、废水、废渣、粉尘、恶臭气体、放射性物质以及噪声、振动、电磁波辐射等对环境的污染和危害。

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。
