Thermoluminescence, noble gases, and the tracks of iron-group elements and cosmogenic radionuclides of various half-lives were examined in the fresh-fallen Ash Creek (L6) and Tamdakht (H5) chondrites. The experimental information thus obtained and theoretical simulations were used to study the shock-thermal and exposure histories of the chondrites, to evaluate their preatmospheric sizes and masses, values of ablation, the sizes of their orbits, and to monitor the distribution and variations in cosmic radiation in the heliosphere during the transitional period of minimum between solar cycles 23 and 24.
