ABSTRACT
Almost all studies on the radioactive content of mushrooms have been centered on 137Cs and, to a lesser extent, on 40K. Other alpha and beta emitters have not been fully investigated and, therefore, their contribution to the dose due to consumption of mushrooms is not taken into consideration. We have studied the incorporation of several radionuclides: into mushrooms using two approaches - laboratory and natural conditions. Pleurotuseryngii was cultured under controlled laboratory conditions, and was found that 134Cs was incorporated to a greater extent in the mushroom than the rest of radionuclides, and 239Pu at least. These results were confirmed by the uptake under natural conditions: 137Cs > 228,230,232Th ≈ 234,238U ≈ 90Sr >> 239+240Pu. The contribution of thorium and uranium to the dose due to mushroom consumption in Spain is of the same order of magnitude as that of 137Cs.
