Abstract
Fifteen soil and nighnteen sediment samples were collected in-front of different cities along Rashid bransh of the River Nile; Banha, Quesna, Berket-Elsaba, Kafr-Elshekh, Desouk, Kafr-elzayyat, Elbehera and Rashid. Natural radioactivity concentrations of

and sediment samples from Banha, Quesna, Berket-Elsabaa, Kafr-Elshekh, Desouk and Elbehera fall within the international recommended values. Nevertheless, a high natural background radiation zones are detected at Kafr-Elzayyat region due to the presence of a fertilizer factory and at Rashid region due to the presence of black sand deposits that are dominated there. The average activity concentrations of 26Ra, 232Th and 4°K) for soil samples from Banha, Quesna, Berket-Elsabaa, Kafr-Elzayyat and Rashid regions are (14.4±0.84, 13.1±1.08 and 216.1±4.8 BqA<:g), (10.7±0.7, 9.1±1.03 and 354.6±6.3 BqA<:g),
(10.3±0.72, 7.5±0.4 and 245±3.6 BqA<:g), (108.6±1.86, 9.8±1.037 and127±5.2 Bqlkg), (46±1.23, 61±1.4 and 83±3.4 BqA<:g), respectively. The corresponding results for sediment samples from Berke-Elsabaa, Kafr-Elshekh, Desouk, Kafr-Elzayyat, Elbehera and Rashid regions are (14.6±0.55, 13.±0.92and 299±5.9 BqA<:g), (17.3±1.21, 20.23±2.3 and 265±6.3 BqA<:g), (11.6±0.67, 9.6±0.8 and 355.3±7.3 BqA<:g), (11.5±0.56, 6.5±0.71 and 249±6.63 BqA<:g), (21±1.11, 16.4±0.997 and 371.33±6.7 BqA<:g), (93.85±1.4,
112±1.78 and 119±3.66 BqA<:g), respectively. The radiation hazard (absorbed dose rate, radium equivalent activity, the annual effective dose equivalent, hazard indices, gamma
index and excess life time cancer risk) are calculated and compared with the previously reported data. High values for some of the radiation health parameters are adopted at Kafr-Elzayyat and Rashid regions representing a serious problem to public because they use the soil and sediment as a constructing materials for their buildings.
