放射性的

As a tracing agent , the radioactive isotope has a high sensitivity for detection.

放射性同位素作为示踪剂，其检测灵敏度高，在染色和盐类示踪剂不能奏效的情况下，放射性示踪剂都能得到成功。

One of development trends is to solidify the radioactive waste and then to bury it.

对放射性废物进行固化处理后理入地下已经成为放射性废物处置的发展趋势。

Article 47 It is prohibited to import radioactive wastes or radioactively polluted articles into the territory of the People's Republic of China or to transfer them via the territory of the People's Republic of China.

Some isobars or matrix may interfere in mass spectrometry analysis, and the low background technology is needed for radiochemical method .

这种包装盒既可以进行辐照，辐照后，也可以直接进行放射性测量，以避免辐照前后放射性测量的几何影响。

Radioisotope scan / gamma camera scan - this uses a very small amount of radioactive iodine.

放射性同位素扫描/γ相机扫描-这用途非常少量的放射性碘。

3 Patients were in the acutestage,〓FDG and 〓NH〓 PET showed brain stem infarction in 2 patients, while CT was normal. MRA of one of them showed right vertebral artery obstruction. One case showed focal infarction within the territory of the right middle cerebral artery 12 hours after stroke onset.〓NH〓 uptake was reduced in right frontoparietal lobe, putamen and part of thalamus, while hyperperfusion was observed in ipsilateral head of caudate nucleus and a portion of thalamus.

急性期3例，2例〓FDG和〓NH〓均示病灶位于右侧脑干为放射性缺损区，CT检查均未显示，1例MRA示右侧椎动脉阻塞：另1例〓FDG示病灶在右侧大脑中动脉区域，与12小时CT所示病灶范围相同，但12小时的〓NH〓示右侧额、顶叶，壳核和部分丘脑为放射性减低和缺损区，而同侧尾状核头部和部分丘脑为过度灌注；发病24小时〓FDG显示除〓NH〓所见缺损区外，右侧额、顶叶部分区域和右侧尾状核头部代谢异常增高，血流和代谢有不一致处。

The study proved that uranium and thorium tend to detach from each other in hypergenesis while they are tightly paragenous in the endogenic process.

而这些稀有元素多含有放射性同位素，因此在对这种稀有多金属矿开采过程中的放射性污染问题也应该得到重视。

The most common grade 3 to 4 adverse events were radiation mucositis, radiation dermatitis, lymphopenia, and neutropenia.

最常见的3至4级不良事件为放射性粘膜炎、放射性皮炎、淋巴细胞减少症和中性粒细胞减少症。

The patients in treatment group were given Tanreqing Injection 20ml intravenouslly guttae and radiotherapy.

对照组单纯放疗。结果：治疗组和对照组放射性肺炎发生例数分别是5(11.3%)和14(30.4%)，两组之间有显著差别(P.05)，且治疗组无2级及以上放射性肺炎的发生。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
