摘要：

The stability of radiation-induced radicals in solid H2O and CO2 was investigated to study the possibility of future ESR dating in outer planets, their satellites and comets in the solar system (Triton and etc.). Solid samples were irradiated by gamma rays at 77K and measured with ESR at several temperature to obtain the isothermal decay time of the signal intensity. Extrapolation of the straight line in the Arrhenius plot of the decay time gave the lifetime of the defects at the ambient temperature of outer planets and their satellites. ESR dating of an outer planet is possible with radiation-induced radicals in ice and dry ice.
