The present work used the integrated Carbone γ-ray spectrometric data and HPGe γ-ray spectrometer data to the prospect of radioactive zones at the Sibaiya area, Central Eastern Desert, Egypt. Carbone γ-ray spectrometric survey revealed ten uranium anomalies distributed along the car traverse from west to east direction have values of 240, 104, 44, 34, 150, 124, 232, 132, 60, and 90 ppm, respectively. These significant anomalies are associated mainly with phosphates mines characterized by a substantial increase of eU/eTh and eU/K ratios. Ten phosphate samples were collected from the determining anomalies. They were analyzed using the HPGe detector gamma-ray spectrometer. It was found that the results of radioelement concentrations by carborne survey agree well with that obtained by HPGe. The average activity concentration for the Sibaiya phosphate samples under study is 152.5, 947, and 33.2 Bq/kg against the worldwide accepted limit of 412, 33, and 45 Bq/kg for ⁴⁰K, ²³⁸U, and ²³²Th, respectively. The radium equivalent ranges from 499 to 3484.9 Bq/kg, which is higher than the recommended value 370 Bq/kg. The external hazard's (H_ex) calculated values range from 1.35 to 9.42 mGy/yr, and the internal hazard (H_in) ranges from 2.58 to 18.69. These indexes must be lower than unity to keep the radiation hazard insignificant. The value of the radioactivity level index (Iγ) is found to be more than unity, which varies between 1.68 and 11.63. The dose rate (D_R) ranges from 149.5 to 970 nGy/h, higher than the international mean value of 55 nGy/h. The annual effective dose ranges from 0.18 to 1.19 mSv, which less than unity in almost all values. Meanwhile, the values of activity of ²²⁶Ra ranged from 454 to 3429 Bq/kg and the mean of mass radon exhalation rate (J_m) is 6615 mBq kg⁻¹ h⁻¹ which is lower than the worldwide average.

目前的工作利用综合的Carbone γ射线光谱数据和HPGe γ射线光谱仪数据对埃及中东部沙漠Sibaiya地区的放射性带进行了展望。卡伯恩γ射线能谱测量显示，沿汽车横向自西向东分布的10个铀异常值分别为240、104、44、34、150、124、232、132、60和90 ppm。这些显着异常主要与以 eU/eTh 和 eU/K 比率大幅增加为特征的磷酸盐矿有关。从确定的异常中收集了十个磷酸盐样品。使用 HPGe 探测器伽马射线光谱仪对它们进行了分析。发现碳化测量的放射性元素浓度结果与HPGe获得的结果吻合。^{分别为 40} K、²³⁸ U 和²³² Th。镭当量范围为 499 至 3484.9 Bq/kg，高于推荐值 370 Bq/kg。外部危害 (H _ex ) 计算值范围为 1.35 至 9.42 mGy/yr，内部危害 (H _in ) 范围为 2.58 至 18.69。这些指标必须低于 1，以保持辐射危害微不足道。发现放射性水平指数 (Iγ) 的值大于 1，在 1.68 和 11.63 之间变化。剂量率（D _R) 范围从 149.5 到 970 nGy/h，高于 55 nGy/h 的国际平均值。年有效剂量范围为 0.18 至 1.19 毫希沃特，几乎所有值都小于统一值。同时，²²⁶ Ra的活度值为454至3429 Bq/kg，平均氡呼出速率（J _m）为6615 mBq kg ^-1 h ^-1，低于世界平均水平。
