核物理基础与放射性测量技术：内容主要是核衰变的四种类型、衰变规律、放射性活度及其单位；射线与物质的相互作用，以及γ计数器及液体闪烁仪测量的基本原理和放射性测量的统计误差。

That is a lot better than nothing, at least for nuclear fallout (for which the model was first developed): there the case for being safe not sorry is overwhelming, and once the fallout has fallen, a Geiger counter will tell you whether the model's forecasts of which places would be affected have turned out to be right.

但是，有个宽泛的概念总比什么都没有好，至少对核放射性微尘是如此，而这种电脑模型最初就是为核放射性微尘而研制出的，因为在这方面，未雨绸缪显得十分重要。且一旦放射性微尘沉降下来，盖格计数器就会告诉你模型所预报的受影响地区是否准确。

By analyzing radionuclides such as uranium, neptunium and plutonium in environmental samples, which were collected in the immediate environment of a nuclear process or nuclear site, researchers can detect evidence of the corresponding nuclear activities.

Methods Proteins existed in adult Schistosoma japonicum membrane were extracted by Triton X-100 and purified through reverse-phase high performance liquid chromatography,and the main protein peaks were then collected separately. 125 I-LDL of human plasma as the ligand, through the radioautography and radioligand binding assay, the protein which can bind human serum 125 I-LDL specifically was identified.

自人工感染家兔的肠系膜下静脉取日本血吸虫成虫，用非离子去污剂TritonX 10 0抽提出日本血吸虫成虫表膜蛋白，反相高效液相色谱进行分离纯化后，收集各主要分离蛋白峰，以12 5I标记的人血浆低密度脂蛋白作为放射性配体，经放射性自显影及放射性受体配体结合分析鉴定能与人血浆12 5I LDL特异结合的蛋白。

One, in fact, almost all taken from the natural rock, used to bake the tiles in the soil, more or less contain a certain amount of radioelement, of course, will not cause radioactive danger, when more than a certain amount of radioactive material, would pose a threat to human health.

一、事实上，几乎所有采自大自然的岩石、烧制瓷砖用的泥土等，或多或少都含有一定量的放射性元素，当然，并非都会对人体造成放射性危害，只有当放射性物质超过一定数量时，才会对人体健康造成威胁。

The high rotten coal (including the anthracite and meager coal ) radioactive level is relatively low,( 238U: 29.1Bq/kg , 232Th: 25.9Bq/kg , 226Ra: 37.5Bq/kg), obviously lower than the radioactive levels of the brown coal and bituminous coal, and fluctuating range little relatively stable until Lincang uranium germanium colliery HeKai Tian little dragon's pool power plant make , investigate than right far correctly, prove natural radioactive nuclide (238U , 232Th , 226Ra ) than activity transformation in the course of utilizing and give locality radiate influence that environment bring.

高变质煤放射性水平相对较低，（238U：29.1Bq/kg、232Th：25.9Bq/kg、226Ra：37.5Bq/kg），明显低于褐煤和烟煤的放射性水平，且波动范围较小、相对稳定通过对临沧铀锗煤矿田和开远小龙潭电厂作出调查比对，说明了天然放射性核素（238U、232Th、226Ra）比活度在利用过程中的转移以及给当地放射环境带来的影响。

Zirconolite-rich synroc is ideal solidification material for solidifying high level radioactive waste .

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
