Gamma and alpha emitting radionuclides in some Algerian soil samples

Characterization of <sup>137</sup>Cs in Riyadh Saudi Arabia Soil Samples

“…Soils vary considerably in chemical composition, but their relative shielding effectiveness depends mainly on density and water content and, therefore, mass attenuation coefficient varies with different water contents (%) of soil and gamma-photon energy. Mass attenuation coefficient for a typical soil of density 1.625 g•cm 3 containing 30% water content by weight and 20% air by volume against gamma-ray energy of 661.6 keV for 137 Cs has been calculated to be 0.0780 cm 2 •g -1 from the given data available in the literature [14]. The x of constant photon flux considered in the present study, the mass absorption coefficient is determined to be 0.0316 cm 2 •g -1 at 661.6 keV energy using the reported data [12].…”

Cambios de radón en suelo y elementos químicos mayores y trazas en agua subterránea asociados a actividad sísmica

“…El ambiente contribuye a la exposición de los seres vivos a la radiación gamma la cual proviene de la geología local, de los materiales de construcción, de la concentración de isótopos radiactivos en el tejido humano, de la ingesta de agua y de los alimentos, etc. (Shenber, 1997;Noureddine et al, 1997;Saito et al,1998). En este trabajo se utilizará la definición de "dosis gamma" cuando se quiera referir a "dosis absorbida producida por la radiación gamma".…”
