Soil–fungi transfer coefficients: Importance of the location of mycelium in soil and of the differential availability of radionuclides in soil fractions

Radiocaesium activity concentrations in macrofungi from Galicia (NW Spain): Influence of environmental and genetic factors

“…The highest 137 Cs activity level detected (Baeza et al, 2004b) corresponds to the species H. cylindrosporum, suggesting that this genus has a great capacity to accumulate radiocaesium. In the present study, L. deliciosus presented a concentration of 291 7510 Bq kg À 1 dw, which is a little higher than that obtained by Baeza et al (2004aBaeza et al ( , 2004bBaeza et al ( , 2005.…”

“…In contrast, our study showed that H. repandum was the species that reached the highest TF, with a value of 57.41. The genus Tricholoma and the species L. deliciosus also significantly incorporated 137 Cs in comparison to the rest of the species (Baeza et al, 2005). In this Baeza's study, T. portentosum and L. deliciosus reached values of 7.71 and 16.59 respectively.…”

Artificial and natural radioactivity in edible mushrooms from Sao Paulo, Brazil

“…Wang et al (1998) Ra activity concentrations found were higher than that reported by Baeza et al (2005) Ra according to Shanthi et al (2010) in Indian vegetables, fruits and tuber. Pietrzak-Flis et al (2001) All the activity concentrations measured for Ra-isotopes in Brazilian mushrooms lie within the range of vegetable foodstuffs as There are many factors affecting the level of radioactivity in mushrooms.…”

Soil-to-fungi transfer of 90Sr, 239+240Pu, and 241Am

“…To this end, we selected a semi-natural ecosystem located in Muñoveros, province of Segovia (Spain), with a high productivity of fungi. In a previous work [11], it had been found that the majority of fungal mycelium in the soil of this ecosystem was located in the surface soil (0-5 cm). Hence, this layer and several species of fungi were collected *Author for correspondence (E-mail: ymiralle@unex.es).…”
