The mass attenuation coefficients (mu/rho) of Rhizophora spp. were determined for photons in the energy range of 15.77-25.27 keV. This was carried out by studying the attenuation of X-ray fluorescent photons from zirconium, molybdenum, palladium, silver, indium and tin targets. The results were compared with theoretical values for average breast tissues in young-age, middle-age and old-age groups calculated using photon cross section database (XCOM), the well-known code for calculating attenuation coefficients and interaction cross-sections. The measured mass attenuation coefficients were found to be very close to the calculated XCOM values in breasts of young-age group.
测定了红树属植物在15.77 - 25.27 keV能量范围内光子的质量衰减系数（μ/ρ）。这是通过研究来自锆、钼、钯、银、铟和锡靶的X射线荧光光子的衰减来进行的。将结果与使用光子截面数据库（XCOM）计算的青年、中年和老年组平均乳腺组织的理论值进行了比较，XCOM是计算衰减系数和相互作用截面的著名代码。发现测量的质量衰减系数与青年组乳腺中计算的XCOM值非常接近。
