Monitoreo de la dosis efectiva anual (DEA) en suelos superficiales de los arrozales de Ahero, Kenia
Resumen
Se investigaron las dosis efectivas anuales (DEA) tanto de DEA (dentro) como de AED (fuera) en los suelos superficiales de los campos de arroz de Ahero, Kenia. El riesgo para la salud asociado de los suelos de los cuatro campos (Campo 1, Campo 2, Campo 3 y Campo 4) se midió utilizando una técnica espectrométrica de rayos gamma que emplea un detector dopado con yoduro de sodio y talio. Se recolectaron cinco muestras de suelo superficial a una profundidad de 15 a 20 cm del Campo 1, Campo 2, Campo 3 y dos muestras del Campo 4. La DEA promedio (in) de 0,30 ± 0,01 mSv/y una DEA promedio (fuera ) de 0,20 ± 0,01 mSv/y para el campo 1, un DEA promedio (in) de 0,19 ± 0,01 mSv/y, un DEA promedio (out) de 0,20 ± 0,01 mSv/y para el campo 2, un DEA promedio (in) de 0,28 ± 0,01 mSv/y y un DEA (salida) promedio de 0,18 ± 0,01 mSv/y para el campo 3 y un DEA (entrada) promedio de 0,34 ± 0,01 mSv/y y un DEA (salida) promedio de 0,23 ± 0,01 mSv/ y para el campo 4. Todos los valores de DEA, tanto dentro como fuera de los cuatro campos, estaban por debajo del nivel recomendado de 1 mSv/y. Los valores indican que no existe ningún riesgo para la salud asociado con los suelos superficiales del área de estudio para los agricultores y la población en general.
