Abstract:

The analysis of the elemental composition of wild mushrooms that had been collected in the territory near different cities in Russia was carried out. Analytical determinations of 27 chemical elements and individual radionuclides (³²⁸U, ¹³⁷Cs, etc.) were performed using nuclear-physical methods of analysis: X-ray fluorescence, gamma activation, gamma spectrometric and track. The dependences of the content of elements and radionuclides on the kind of the mushroom were revealed. The difference in the index accumulation of elements in the mushrooms of various ecological groups was shown. The kinetics of the ¹³⁷Cs desorption from different parts of the mushrooms body into the water phase was investigated. The assumption about the possibility of the cosmic dust being on the surface of the mushrooms was made.
