Upon analysis we found that 56% were only on at least 50% of the recommended background dose.
经分析我们发现，仅56%的患者在接受所推荐背景剂量的至少50%。
For most people more than half of their natural background radiation dose comes from radon, a radioactive gas that can accumulate in homes, schools and workplaces.
对大多数人来说，他们自然环境辐射剂量的一半以上来自氡—一种可聚集在家庭、学校和工作场所的放射性气体。
Summary of Background Data. High dose methylprednisolone sodium succinate (MPSS) for the patients with acute spinal cord injury has been considered standard treatment in the several countries.
急性脊髓损伤时应用大剂量甲基强的松龙治疗在一些国家一直被认为是标准治疗。
These results have provided useful bases for recommending reference dose of related natural radiation exposure, parameters of Chinese reference Man and background value of radiation monitoring.
这些结果为推荐我国天然辐射剂量参考值、我国参考人相应参数和辐射监测背景值提供了有用依据。
Today it is different, patients are different, and they have different background treatments with much more ACE inhibitor treatments, higher dose levels, etc.
今天一切都不同了，患者是不同的，且他们有着不同的背景治疗，如更多的ACE抑制剂治疗，更高的剂量水平等。
This is called background radiation and levels vary from place to place, though the average dose is fairly constant.
辐射强度会因地点而异，但平均辐射量实则大致相同。
Background: Although morphine has been shown to induce bowel dysfunction in a dose-dependent fashion, in most relevant studies it was investigated in single bolus injection.
背景：吗啡会引起肠蠕动失调，而且是以剂量效应的方式来表现，只是之前这类的研究是以单次剂量的给予来探讨。
Below the threshold dose level, no adverse events above the response at the control level which is called the background response occur, then background response also occurs at the threshold level.
当剂量水平低于这个门阀剂量水平时，该剂量水平下的反应要比控制剂量下的反应即背景反应低，并且本文假定该门阀剂量水平下的反应与背景反应相同。
Background: There has been resurgence of interest in lung cancer screening using low-dose computed tomography. The implications of directing a screening programme at smokers has been little explored.
背景：用计算机体层摄影术对肺癌的筛选有着复活再现的兴趣。这意味着对于吸烟者进行直接筛选的规划要付出一点冒险。
