摘要

高海拔地区的特点是缺氧和低气压。暴露在高海拔地区会影响人的生理机能，特别是血氧浓度和饱和度。此外，氧气、二氧化碳和真空已知会影响用于氡探测的某些聚合物。在本研究中，利用α径迹探测器(CR-39塑料)评估了在低海拔正常氧气和大气压下测量的岩石、土壤、植物(野生草本植物)和水样中的氡呼出率和有效镭，并与在高海拔(海拔2412 m)低氧和低压条件下的相应测量结果进行了比较。数据表明，高海拔条件对氡浓度及其呼出率的测量有轻微影响。

Effect of the altitude on the concentration and exhalation rate of radon

High altitude is characterised by hypoxic and hypobaric conditions. Exposure to high altitude is known to affect human physiology, specially blood oxygen tension and saturation. Also, oxygen, carbon dioxide and vacuum are known to affect some polymers used in radon detection. In the present work alpha track detector (CR–39 plastic) was used to assess the radon exhalation rates and effective radium in rock, soil, plants (wild herbs) and water samples measured at low altitude with normal oxygen and atmospheric pressure and compared with the corresponding measurements in hypoxic and hypobaric conditions at high altitude (2412 m above sea level). The data indicated that high–altitude conditions slightly affect the measurements of the radon concentration and its exhalation rate.
