Studies on neutron and photon kerma parameters for human body organs
A study on neutron kerma factors and photon air-kerma for human organs is presented for neutron energy range 2.53×10-8 MeV to 29 MeV and photon energy range 1 keV to 20 MeV. The human organs water equivalence for photon and neutron, is also presented. The ratio of the mass-energy absorption...

| Summary: | A study on neutron kerma factors and photon air-kerma for human organs is
presented for neutron energy range 2.53×10-8 MeV to 29 MeV and photon energy
range 1 keV to 20 MeV. The human organs water equivalence for photon and
neutron, is also presented. The ratio of the mass-energy absorption
coefficients of human organs to water was found constant and unity above 100
keV, whereas there was a large difference for energies below 100 keV. The
neutron kerma factors of human organs and water are found of same order of
magnitude whereas differs for air. The neutron kerma factors of human organs
and tissue substitutes were found to be equal to water for neutron energies
between 63 eV and 200 keV. The skeleton-cortical bone was found to be away
from water equivalence for low-energy photons and high-energy neutrons. |
