Comparison of Mass Attenuation Coefficients of Martian Soils With Earth Soils

摘要

The mass attenuation coefficient is the basic quantity used in calculations of the penetration and the energy deposition by photons (x-ray, γ-ray, bremsstrahlung) in biological, shielding and other materials. The nature of the soils of earth and mars were theoretically investigated using mass attenuation coefficients. The x-ray fluorescence analysis results of 3 different earth soils for low Z elements commonly found in major and minor quantities in soil and rock were compared with 3 soils and 2 rock samples of mars analyzed by alpha spectrometry. Detailed results are discussed. Similarities regarding the environment of 2 planets are investigated.
