放射性

Radioactivity is the energy given off by rays from a few unstable elements such as uranium and thorium.

放射性是某些不稳定元素如铀和钍的射线放射出来的能量。

Thorium is radioactive; therefore, you must always follow manufacture's warnings, instructions and the MSDS for its use.

钍放射性；因此，你必须始终按照制造的警告指示和总署供其使用。

The contents of 226Ra and 232Th of honeycomb briquette were used to calculate the contribution of honeycomb briquette burning to indoor radon and thoron and their radiation dose to the residents.

应用γ能谱测定了西安市蜂窝煤中天然放射性核素226Ra、232Th和40K的含量，并初步分析了取暖期蜂窝煤燃烧对室内氡及钍射气浓度的贡献，以及所致居民剂量。

In the process of mining, milling and steel and rare earth melting, thoron element was released to the accessible environment together with smoke, wastewater and disposed slag, leading to radioactive contamination to the environment.

在采矿、选矿、钢铁和稀土冶炼等生产中，钍元素随烟尘、废水和废渣排放至环境中，造成放射性污染。

The thoriaum and uranium bearing radioactive materials associated with Baotou Municipal Baiyunerbo Mine is typical thoron associated ore.

包头市所属白云鄂博矿平均伴生 0 。0 4 %钍和 0 。0 0 1 %铀放射性物质，是典型的钍伴生矿。

Objective:To study clinical value of radiocystitis therapy with thrombin intra-bladder perfusion.

目的 ：探讨凝血酶膀胱灌注治疗放射性膀胱炎的临床应用价值。

Clinical indications for RAI are based on pathology, postoperative thyroglobulin, and intraoperative findings.

该放射性碘治疗临床适应证是基于病理学类型、术后甲状腺球蛋白水平和术中冰冻切片的检查结果。

Postoperative RAI therapy is to destroy any remaining normal thyroid tissue as a source of thyroglobulin production, to improve accuracy of follow-up testing, said Dr.

术后放射性碘治疗可摧毁所有分泌甲状腺激素的残余正常甲状腺组织，以提高后续检查的准确性。

Quantitative assessment of the tracer concentration distribution across the body is the key for functional study of the tissues.

核医学的优势是对这些放射性示踪剂的定量分析。

Objective To investigate the effect of implanted radioactive 125I seed on normal tissue structure of trachea in rabbits.

目的 研究放射性125I粒子植入对家兔正常气管组织结构的影响及其安全性。

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.
