Thermoluminescence (TL) of calcite (CaCO3) irradiated by γ-rays has been measured from a distance by treating with a CO2 infrared laser beam. The diameter of a TL spot at the exposure site increased due to thermal diffusion and became dark. The surrounding area showed TL in the form of a broad ring. TL images obtained after the exposure were compared with those simulated by numerically solving the equation of three-dimensional heat diffusion using the parameters of the TL peaks, i.e., frequency factors νoI= νoII = 5 × 1011 s-1 and activation energies EI = 1.28 and EII = 1.58 eV; the thermal conductivity and the specific heat. The remote TL (R-TL) may be used in the future for planetary survey by heating or exciting a ground object front a rover or from a spacecraft.
