氢能导致肺癌的作用已被大量的实验结果和流行病学调查资料所证实,肺癌发生率与氡子体的累积暴露量存在“线性无阈”的关系。两个矿务局的初步调查表明煤矿井下也存在较高浓度的氡,对此有关领导与部门应给予充分的重视。
The role of hydrogen in lung cancer has been confirmed by a large number of experimental results and epidemiological investigation data. There is a “linear, threshold-free” relationship between the incidence of lung cancer and the cumulative exposure to radon progeny. Preliminary investigations by two mining bureaus indicate that there is also a high concentration of radon in coal mines, and the relevant leaders and departments should give due attention.
