The results based on 2-year long measurements 01 Jan. 2016–2031 Dec. 2017 have been used for discussing the influence of tunnel lining on the size of 222Rn activity concentration and the impact of the employed rock mass insulation on natural convective air exchange. In April, air movement started when the temperature was at least 7 °C lower than the mean inside. Between May and October, an increase to 9 °C above the underground temperature resulted in an increase of radon concentration. An unconstrained convection process did not start until November and it continued until the end of March. The reinforced concrete lining insulated the fractured and absorptive rock mass. The roof and the sidewall lining had little impact on air movement process.

Książ城堡荣誉勋章下的选定地下工程中衬砌结构对氡行为影响的评估

基于 2016 年 1 月 1 日至 2031 年 12 月 2 年的为期 2 年的测量结果已用于讨论隧道衬砌对 222Rn 活动浓度大小的影响以及采用的岩体隔热对自然对流空气交换的影响。4 月,当温度至少比室内平均温度低 7 °C 时,空气开始流动。在 5 月至 10 月期间,地下温度升高至 9 °C 导致氡浓度增加。一个不受约束的对流过程直到 11 月才开始,一直持续到 3 月底。钢筋混凝土衬砌隔离了破裂和吸收性岩体。屋顶和侧壁衬里对空气流动过程的影响很小。
