Abstract: The content of the isotopes 3H, 14C, 36Cl, 55Fe, 59Ni, 63Ni, 60Co, 90Sr, 93mNb, 108Ag, 133Ba, 134Cs, 137Cs, 154Eu, and 155Eu in the GRP-2-125 graphite from the reactor of Power Unit 2 at the Chernobyl Nuclear Power Plant was measured. The results were compared with the calculations and literature data. Some regularities and correlations were revealed in the content of various radionuclides in graphite. Graphite porosity and desorption of radionuclides from graphite were studied.
