Resumen
A study on neu tron kerma fac tors and pho ton air-kerma for hu man or gans is pre sented for
neu tron en ergy range 2.53×10–8 to 29 MeV and pho ton en ergy range 1 keV to 20 MeV. The
human or gans wa ter equiv a lence for pho ton and neu tron, is also pre sented. The ra tio of the
mass-energy ab sorp tion co ef fi cients of hu man or gans to wa ter was found con stant and unity
above 100 keV, whereas there was a large dif fer ence for en er gies be low 100 keV. The neu tron
kerma fac tors of hu man or gans and wa ter are found of same or der of mag ni tude whereas dif -
fers for air. The neu tron kerma fac tors of hu man or gans and tis sue sub sti tutes were found to
be equal to wa ter for neu tron en er gies be tween 63 eV and 200 keV. The skel e ton-cor ti cal bone
was found to be away from wa ter equiv a lence for low-en ergy pho tons and high-en ergy neu -
trons.
