Bazı Temel Karbonhidratlar İçin Hızlı Nötron Zırhlama Parametrelerinin Hesaplanması

Bu çalışma, hızlı (veya fisyon enerjili) nötronların canlı hücrelerin pek çoğu için önem taşıyan bazı temel karbonhidratlar tarafından zayıflatılması üzerinedir. Bu amaçla, farklı yoğunluklu on bir çeşit karbonhidrat etkin etkin hızlı nötron sökme tesir kesitleri () ve hızlı nötronları zayıflatma mesafeleri bakımından incelenmiştir. Hesaplamalar NCRP No. 20 (1957)’den derlenen kütlesel sökme tesir kesiti ve karbonhidratlara ait elementsel bileşim verileri kullanılarak yapılmıştır. Elde edilen sonuçlar, seçilen karbonhidratlar içinde hızlı nötronların zayıflatılmasında en büyük rolü Hidrojen elementinin oynadığını göstermektedir. Bildiğimiz kadarıyla bu çalışma, hızlı nötronların seçilmiş olan karbonhidratlara ait etkin hızlı nötron sökme tesir kesitleri üzerine yapılan ilk çalışmadır. Ayrıca, çalışma sonucunda sunulan verilerin ilgili literatüre kayda değer bir katkı sunacağı umulmaktadır.

Calculation of Fast Neutron Shielding Parameters for Some Essential Carbohydrates

This study is concerned with the attenuation of fast (or fission energy) neutrons by some essential carbohydrates which carry importance for most of the living cells. For this purpose, eleven carbohydrates having different densities have been investigated by means fast neutron effective removal cross sections () and attenuation lengths. The calculations have been performed using the mass removal cross section data compiled from NCRP No. 20 (1957) and elemental compositions of carbohydrates. The obtained results show that the Hydrogen element plays the major role for fast neutron attenuation in selected carbohydrates. According to our best knowledge, this could be the first study on the fast neutron removal cross sections of selected carbohydrates. Also, the data presented here is expected to contribute the related literature significantly.

Keywords:

Neutron attenuation, fast neutron removal, attenuation length, carbohydrate.,
