Abstract

Abstract The isotope activity concentration of rocks and bottom sediments was evaluated based on the samples collected from sedimentation ponds and gangue repositories. Radium 226Ra, thorium 228Th and potassium 40K activities were measured by gamma spectrometry using high-purity germanium detector – HPGe 4020. The radiation effect resulting from the presence of natural radionuclides was estimated by radiological hazard indices such as f1 and f2 coefficients, radium equivalent, internal and external hazard indices and absorbed dose rate. Performed measurements and calculations have shown that the bottom sediments are most contaminated. They may pose a serious radiological hazard for present and future generations.

就放射性危害而言，布热什采和西里西亚煤矿的岩石和沉积物作为建筑材料的适用性

摘要根据从沉积池和脉石库采集的样品，对岩石和底部沉积物的同位素活性浓度进行了评价。使用高纯度锗探测器HPGe 4020通过伽马光谱法测量了镭226Ra、钍228Th和钾40K的活性。天然放射性核素的存在产生的辐射效应是通过放射性危害指数估计的，如f1和f2系数、镭当量、内部和外部危害指数以及吸收剂量率。进行的测量和计算表明，海底沉积物受到的污染最大。它们可能对今世后代造成严重的放射性危害。
