dc.descriptionWe confirm the result obtained many years ago at Tien-Shan mountain station with the large 36-m2 lead calorimeter that in extensive air showers (EAS) with energies of few PeV the attenuation of core energy deposit in lead becomes slower than it could be predicted by modern codes. It is shown that this effect is connected with the appearance of the excess of abnormal cores with a large ionisation released in lower layers of the calorimeter and these abnormal EAS cores are most probably produced by high-energy muon groups. A few hypotheses of the excess of muon reach EAS cores are considered. To study the absorption of EAS hadrons and muons in a lead ionization calorimeter, the EAS development in the atmosphere was simulated in the framework of the CORSIKA+QGSJET code whereupon the passage of hadrons and muons through a lead calorimeter has been modeled with using the FLUKA transport code.
