This paper presents the results of natural radioactivity measured for the soil of Qena using gamma-ray spectrometry at ZSR, Hanover University, Germany. Soil samples of radioactive concentrations of ²³⁸U-series (²³⁴Th, ²¹⁴Pb, and ²¹⁴Bi), ²³²Th-series (²²⁸Ac, ²¹²Pb, and ²⁰⁸Tl) and ⁴⁰K were analyzed. Three objectives were set: (1) activity levels by surface soil sampling at 0~30 cm depth, (2) dose rates of gamma radiation, radium equivalent, index hazard, and effective dose, and (3) ambient dose rates.
