Abstract : The natural glow-curves of ten chondrites were measured and compared with the corresponding artificial glow-curves, obtained after irradiation with a beta-dose of 50,000 rad. The differences between the natural and the artificial glow-curves as well as the increase of peak-temperature with decreasing peak-intensity, observed for the natural glow-curves of the various chondrites, can be explained by thermal effects. Either a temperature raise occurred before, during, or after the fall of the meteorites, which caused the low-temperature part of the natural glow-curves to fade out, or the shallow, low-energy traps, responsible for the low-temperature part of the natural glow-curves never were filled, due to the low dose rate of cosmic radiation.
