Until recently the exposure associated with the short-lived radon daughters (S-LRD) was thought to apply exclusively to uranium ore mines. The last few years have brought information on the presence of this hazard in non-uranium raw materials mines, e.g. in hard coal mines. It was ascertained that the hard coal mines exposure to the S-LRD lead to increase of frequent of larynx cancer cases in this population on the Upper Silesia Region. 67 Upper Silesia hard coal mines were divided for three groups: I.--(4 number of mines), highest hazard, i.e. < 2.5 microJ/m2 (mean value of potential alpha-energy concentration of S-LRD; II degrees-28, mean hazard, i.e. > 0.4- < 2.5 microJ/m3; III.--35, lowest hazard (risk relative level-RR = 1.00), i.e. < 0.4 microJ/m3. In compare these 3 groups taking into consideration tobacco smoking standardized we have following results of the RR: for suffering natives from larynx cancer: I.--2.86 (at p < 0.05), II.--1.08, at III.--1.00, and for immigrants: I.--6.97 (at p < 0.05), II.--2.09, at III.--1.00 (it is reference level.
直到最近，与短寿命氡子体（S-LRD）相关的暴露还被认为仅适用于铀矿。过去几年带来了关于这种危害在非铀原材料矿山（如硬煤矿）中存在的信息。已确定上西里西亚地区硬煤矿中S-LRD的暴露导致该人群喉癌病例数增加。67个上西里西亚硬煤矿被分为三组：I组（4个煤矿），最高危害，即<2.5微焦耳/平方米（S-LRD潜在α能量浓度的平均值）；II组28个，中等危害，即>0.4 - <2.5微焦耳/立方米；III组35个，最低危害（相对风险水平RR = 1.00），即<0.4微焦耳/立方米。在考虑吸烟标准化的情况下比较这三组，我们得到RR的以下结果：对于患喉癌的当地人：I组为2.86（p < 0.05），II组为1.08，III组为1.00；对于移民：I组为6.97（p < 0.05），II组为2.09，III组为1.00（这是参考水平）。
