Two detector media suitable for a warm liquid ionization chamber filled with tetramethylsilane (TMS) and tetramethylgermanium (TMG) were exposed to γ-radiation from a 60Co source up to a dose of 579 Gray and 902 Gray, respectively. The electron lifetimes and the free ion yields were measured as a function of accumulated radiation dose. A similar behavior of the electron lifetimes and the free ion yields with increasing radiation dose was observed between the TMS and TMG ionization chambers
