dc.description.abstract | La radiactividad del suelo afecta al cuerpo humano. Este estudio determinó la actividad del 238U, 232Th and 40K (NORM) en 164 suelos urbanos de trece ciudades del estado de Chihuahua, México. Se calculó la tasa de dosis absorbida y de dosis efectiva anual. Se usó un detector de germanio hiperpuro (HPGe), modelo Ge 2020, Termo y Dewar 7500 SL marca CANBERRA. Análisis de Varianza (ANOVA) y una prueba de Turkey fueron corridas para detectar las dife-rencias estadísticas. Los promedios de actividad fueron de 36.8 Bq kg–1 para 238U, 41.4 Bq kg–1para 232Th y 805.7 Bq kg–1 para 40K. La tasa de dosis absorbida estuvo en un intervalo entre 36 nGy h–1 a 83 nGy h–1, mientras la dosis efectiva anual varió de 1.02 mSv y–1 a 0.44 mSv y–1. Los resultados muestran que algunos valores exceden los promedios mundiales y que están entre los más altos valores mundiales | es_MX |

dc.description.abstractEnglish | Soil radioactivity affects the human body. This study determinates the 238U, 232Th and 40K activity (NORM) in 164 urban soils in 13 cities in the State of Chihuahua, Mexico. Absorbed Dose Rate and the Annual Effective Dose were also calculated. Activities were analyzed using a coaxial hyper-pure germanium detector (HPGe), Ge Model 2020, Thermo and Dewar 7500 SL (CANBERRA brand). A one-way variance analysis (ANOVA) was performed and a Tukey test was applied to identify mean differences. Activity averages were 36.8 Bq kg–1 for 238 U, 41.4 Bq kg–1 for 232Th and 805.7 Bq kg–1 for 40K. Calculated absorbed dose rate ranged from 36 nGy h–1 to 83 nGy h–1 while Annual Effective Dose varied from 1.02 mSv y–1 to 0.44 mSv y–1 . Results suggest that some levels exceed global averages and are among the highest levels of natural radioactivity in the world. | en |
