The project focused on classifying the level of irradiation from natural ionising radiation sources for workers in publicly accessible caves and in caves used for speleotherapy, with applicability to other underground workplace. A correct and accurate procedure (and calculation) is defined for determining the effective dose that workers are exposed to in caves, based on the results of integral measurements of radon volume activity and on the length of time spent by workers in the caves. A review was made of various approaches for evaluating lung irradiation found in the literature. Experimental measurements of cave atmosphere characteristics (continuous measurement of radon volume activity, continuous and integral measurements of radon decay products, interior climatic parameters and aerosol spectra) were the main sources for the methodology.
该项目专注于对在公众可进入的洞穴以及用于洞穴疗法的洞穴中工作的工人所受天然电离辐射源的照射水平进行分类，并适用于其他地下工作场所。基于氡体积活度的积分测量结果以及工人在洞穴中停留的时间长度，定义了一种正确且准确的程序（和计算方法）来确定工人在洞穴中所受的有效剂量。对文献中发现的评估肺部照射的各种方法进行了综述。洞穴大气特征的实验测量（氡体积活度的连续测量、氡衰变产物的连续和积分测量、内部气候参数和气溶胶光谱）是该方法的主要来源。
