Caracterización de la densidad de maderas amazónicas peruanas mediante la atenuación de la radiación gamma y neutrónica

Abstract

Se presenta los resultados de la caracterización de la densidad de muestras de madera, mediante el estudio de los coeficientes de atenuación tanto de la radiación gamma, usando una fuente de cobalto 60 de 75 mCi de actividad, como de neutrones usando una de las facilidades del reactor RP-10 operando a 320 kW de potencia y un flujo neutrónico de 5,6*106 (n s-1cm-2). Los resultados de la medición de los coeficientes de atenuación muestran que la densidad se encuentra influenciada por la humedad y el tipo de madera principalmente. Las mediciones muestran valores satisfactorios al compararse con los valores de referencia y los experimentales. La densidad influye considerablemente con los factores relacionados con la calidad de la madera. Este trabajo siendo parte de proyectos mayores, busca desarrollar sistemas autónomos y portátiles de tecnología nuclear que puedan identificar el tipo de madera, sus propiedades y características para un control adecuado en la explotación y el comercio.

This investigation show the work developed in the characterization of the density of woods by means of the study of the Attenuation Coefficients of the gamma radiation, using a source of cobalt 60 of 75 mCi of activity and neutrons using the Reactor RP10 as source of neutrons working at 320 kW and using a flow of 5,6*106 (n s-1 cm-2), the results of the measurement of the Attenuation Coefficients show that the density is influenced by the humidity and the type of wood mainly, so for, the measurements of the density are in agreement with referential and experimental values. As the density has strong influence with important related factors with wood quality, this work being part of big projects that seek to develop autonomous and portables systems of nuclear technology that can identify the type of wood, properties and characteristics for an adequate control in the exploitation and trade.
