In this work, the activity concentrations (radioactivity) and distributions of natural radionuclides in peat moss samples were investigated. The measurements were performed using HP‐Ge detector and XRD technique. The samples represent six types of soils. The concentrations of radionuclides of 238U, 226Ra, 232Th and 40K are ranged from 17.14 to 130.83, 13.19 to 26.09, 5.33 to 25.2 and 143.26 to 600.31 Bq·kg–1 (dry weight), respectively, for the different samples. This work also highlights that no correlation has been observed between radionuclides present in the samples, which in turn reflects the random method behind the preparation of the samples. The obtained results from the XRD analysis were in good agreement with radiometry measurements. The safety of peat moss uses was limited for certain agricultural crops due to the presence of high percent of sulphur in some types of soil. The radon concentration calculated using the empirical formula is more accurate than those obtained from the manual measurements and significant values were expected to emanate from the samples under investigation.

埃及泥炭藓温室土壤和农业泥中自然存在的放射性同位素分析
在这项工作中，研究了泥炭藓样品中天然核素的活度浓度（放射性）和分布。使用HP-Ge检测器和XRD技术进行测量。样品代表六种类型的土壤。238 U，226 Ra，232 Th和40 K的放射性核素浓度范围为17.14至130.83、13.19至26.09、5.33至25.2和143.26至600.31 Bq · kg –1（干重）分别用于不同的样品。这项工作还强调了样品中存在的放射性核素之间未发现相关性，这反过来反映了样品制备背后的随机方法。XRD分析获得的结果与辐射测量结果非常吻合。由于某些类型的土壤中存在高百分比的硫，因此对于某些农作物而言，泥炭藓使用的安全性受到限制。使用经验公式计算出的concentration浓度比通过手动测量获得的concentration浓度更准确，并且预期从所研究的样品中得出significant值。
