Dosimetry calculations for BNCT with Monte Carlo N-Particle (MCNP) tipically take into account, for any organic tissue, the thermal scattering treatment for hydrogen bound in bulk water. However, in these tissues, hydrogen is also present in macromolecules (protein, lipids, etc.) and in confined water. In previous studies with the MCNP code we have determined that the differences in thermal neutron flux calculations using libraries for hydrogen in polyethylene or hydrogen in water, in phantoms of adipose tissue, can reach values of 9%, depending on the type of source and irradiated geometry.

Abstract
Dosimetry calculations for BNCT with Monte Carlo N-Particle (MCNP) tipically take into account, for any organic tissue, the thermal scattering treatment for hydrogen bound in bulk water. However, in these tissues, hydrogen is also present in macromolecules (protein, lipids, etc.) and in confined water. In previous studies with the MCNP code we have determined that the differences in thermal neutron flux calculations using libraries for hydrogen in polyethylene or hydrogen in water, in phantoms of adipose tissue, can reach values of 9%, depending on the type of source and irradiated geometry.File in questo prodotto:
