Los hongos juegan un papel importante en la movilidad y acumulación de sustrato, y pueden utilizarse para determinar los niveles de concentración de radionucleidos en el medio ambiente. Este estudio muestra la diversidad de radionucleidos presentes en el suelo del Monumento Natural Loma Isabel de Torres en algunos hongos basidiomicetos silvestres. Los radionúclidos se determinaron con un espectrómetro gamma de Germanio Hiper Puro GX5019 con analizador de espectro digital DSA 1000, utilizando el software Genie 2000. Los organismos analizados fueron Ramaria sp., Sparassis spathulata, Russula sp. y Boletus sp. La actividad específica se obtuvo para cada uno de los basidiocarpos y su respectiva muestra de sustrato circundante. Además, se calculó el factor de bioacumulación. En los hongos se detectaron 137Cs y 40K, mientras que no se encontraron 232Th, 226Ra ni 210Pb. Las muestras de suelo tomadas a mayor altura presentaron una mayor concentración de 226Ra. Con base en estos hallazgos, se recomienda continuar el trabajo en esta línea de investigación.
Fungi play an important role in the mobility and accumulation of substrate, and can be used to determine the concentration levels of radionuclides in the environment. This study shows the diversity of radionuclides present in the soil of the Loma Isabel de Torres Natural Monument in some wild basidiomycete fungi. Radionuclides were determined with a GX5019 Hyperpure Germanium gamma spectrometer with a DSA 1000 digital spectrum analyzer, using Genie 2000 software. The organisms analyzed were Ramaria sp., Sparassis spathulata, Russula sp. and Boletus sp. The specific activity was obtained for each of the basidiocarps and their respective surrounding substrate sample. The bioaccumulation factor was also calculated. In the fungi, 137Cs and 40K were detected, while 232Th, 226Ra and 210Pb were not found. The soil samples taken at higher altitudes presented a higher concentration of 226Ra. Based on these findings, it is recommended to continue the work in this research line.
