The paper presents the study of the radioactivity connected with the transport of natural gas by the gas pipeline network in the selected points in Poland. In the scope of the study the measurements of activity concentration of radon (222Rn) in the gas samples, radiolead (210Pb) in spent filter cartridges and dust samples (black powder) collected from the gas pipeline network were performed. The results show that the 222Rn activity concentration in natural gas varies from the detection limit of the applied method (30 Bq/m3) to around 1400 Bq/m3. The 210Pb activity concentration in black powder samples and spent filter cartridges varies from 500 to 17000 Bq/kg and from 200 to 2900 Bq/kg respectively. The black powder with highest 210Pb concentration should be classified as low-radioactive waste according to nuclear regulations.

波兰天然气管道网络的放射性。

本文介绍了在波兰选定地点通过天然气管道网络与天然气运输相关的放射性的研究。在研究范围内，对气体样品中，（222Rn），放射性滤池中的放射性铅（210Pb）和从天然气管网中收集的粉尘样品（黑粉）的活度浓度进行了测量。结果表明，天然气中的222Rn活度浓度从应用方法的检测极限（30 Bq / m3）到1400 Bq / m3左右。黑色粉末样品和用过的滤芯中的210Pb活性浓度分别为500至17000 Bq / kg和200至2900 Bq / kg。最高210Pb浓度的黑色粉末应根据核法规分类为低放射性废物。
