A set of early chemical reactions in grapes of ionization (blobs) arising in tracks of fast electrons and positrons in liquids as well as formed by the Auger electrons in frozen aqueous media around decaying Mössbauer ^{57}Co or ^{119m}Sn nuclei is suggested. The mechanism predicts a correlated variation of the formation probabilities of intrablob final products, namely Fe^{2+}-Fe^{3+} or Sn^{2+}-Sn^{4+} ions, positronium atom and molecular hydrogen with variation of temperature, degree of crystallinity, concentration of electron scavengers. These correlations indicate on similarity of chemical processes as in blobs created by ^{57}Co and ^{119m}Sn after their decay as well as in blobs produced in tracks of fast positrons and electrons.
