The mass attenuationcoefficients and molar extinction coefficients of specific parts (root, aerialpart and flower) of Alyssum pateri subsp. prostratum have been measured employing a Si(Li) detector in theenergy range between 13.92 and 59.54 keV using an 241Am pointsource. In the present study, the obtained experimental mass attenuationcoefficients and molar extinction coefficients for different organs of plantmaterial were compared with the theoretical calculated values for same samples.The results have been shown that the experimental values are in a goodagreement with the calculated theoretical values using WinXCOM program.

Alyssum pateri subsp. prostratum bitkisinin bazı kısımlarının (kök, toprak üstü ve çiçek) kütle azaltmakatsayıları ve molar yok-olma katsayıları 13.92 ve 59.54 keV enerji aralığındabir Si(Li) detektör ve 241Am nokta kaynağı kullanılarak ölçülmüştür.Sunulan bu çalışmada, bitkiselmateryalin farklı organları için elde edilen deneysel kütle azaltmakatsayıları ve molar yok-olma katsayıları teorik hesaplanan değerler ilekarşılaştırılmıştır. Sonuçlar, deneysel değerler ile WinXCOM programkullanılarak hesaplanan teorik değerler arasında iyi bir uyum olduğunugöstermiştir.
