放射性的

Strontium 90, released through nuclear explosions into the air, comes to the earth in rain or drifts down as fallout, lodges in soil, enters into the grass or corn or wheat grown there, and in time takes up its abode in the bones of a human being, there to remain until his death.

由核爆炸释放到空中的锶90以放射性尘埃的形式随雨水或漂浮物落到地球上，留在土壤里，进入地上生长着的草、玉米或小麦等植物体内，最后钻进人体，停留在骨骼里直到人死去。

Strontium and yttrium can be separated by changing the acidity, and it can be used to separate the radioactive Sr from matrix.

通过调节萃取液的pH值，可实现Sr和Y的分离，并可将其用于裂变产物中放射性Sr的分离。

By this time the Curies were so certain of the presence of the new element that they wondered what name it should be given--what it would look like.

至此，居里夫妇确信这种新的放射性元素的确是存在的，他们开始考虑为这新元素命名——它看起来是怎么样的？

The matter that the Curies had discovered was radium. It looked like ordinary salt, but was one million times more radioactive than uranium.

居里夫妇所发现的物质就是镭，看起来它就像普通的食盐一样，而它的放射性却铀要大一百万倍。

A short - lived , radioactive synthetic transuranic element produced from californium and having

铹一种寿命期短的、人工合成的放射性超铀元素，从锎中生成，有质量从255到260的同位素，半衰期从几秒钟到三分钟；原子序数

Unconjugated antibodies show significant efficacy in the treatment of solid tumors by monotherapy and combining with chemotherapy or radiotherapy.

单克隆抗体单治疗和联合化疗、放疗在实体瘤治疗中显示出了很好的疗效，抗体与放射性核素结合的放射免疫性治疗也有明显的疗效。

Unconjugated antibodies show significant efficacy in the treatment of solid tumors by monotherapy and combining with chemotherapy or radiotherapy. Radioimmunotherapy is that antibodies conjugate to radionuclides shows significant efficacy, too.

单克隆抗体单一治疗和联合化疗、放疗在实体瘤治疗中显示出了很好的疗效，抗体与放射性核素结合的放射免疫性治疗也有明显的疗效。

Kelp: Kelp alginic acid can slow down the rate of intestinal absorption of radioactive strontium, so that strontium excreted, and therefore has a role in the prevention of leukemia.

海带：海带中的褐藻酸能减慢肠道吸收放射性元素锶的速度，使锶排出体外，因而具有预防白血病的作用。

Environmental pollution accounting system is a complete set of theoretical method about the accounting of environmental pollution in physical-volume and value as well as the conceptions, methods, classific.

环境污染核算是环境与经济综合核算，即绿色国民经济核算的一部分，是对水污染、大气污染、固体废弃物污染、放射性污染和噪音污染的实物量和价值量进行核算的总称。

In the present data set, the addition of the PFTs or 6MWT did not increase the ability of the dosimetric parameters to predict for acute symptomatic RP.

就目前的数据而言，PFTs或6MWT的加入并不能增加剂量学参数对急性症状性放射性肺病的预测能力。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
