Investigation of Developed Shield Composition to Neutron Shielding in Treatment Room for BNCT to Reduce Clinical Effects

Background and Aim: One of the best radiotherapy methods that have been suggested for the treatment of cancers such as brain, head and neck, skin, and recently liver is boron neutron capture therapy. Therefore, neutron shielding in the treatment room is important because the absorption of neutrons in the shield may lead to the production of gamma rays, which can have destructive effects. While ...

Trabecular bone changes induced by fast neutrons versus gamma rays in mice

Background: The trabecular bone changes in the tibia of C3H/HeN mice were measured 12 weeks after whole body irradiation with various doses of fast neutrons (0-2.4 Gy) or 137Cs-generated gamma-rays (0-6 Gy). Materials and Methods: Serum calcium, phosphorus, estradiol concentration and alkaline phosphatase activity were measured. Tibiae were anal...

An investigation of neutron direct damages at energies of 0.1-2 MeV on the DNA molecules with atomic structure deduced using Geant4 toolkit

This study proposes a method to estimate RBE of fast neutrons using Monte Carlo simulations. This approach is based on the combination of an atomic resolution DNA geometrical model and Monte Carlo simulations for tracking particles. Atomic positions were extracted from the Protein Data Bank. The GEANT4 code was used for tracking the secondary particles generated by fast neutrons during their in...

Induced Pollen Lethals from Seeds of Datura Stramonium Exposed to Radiation from a Nuclear Detonation.

Biological effects of ionizing radiations produced by an explosion of a nuclear device may be complicated by the heterogeneity and extreme intensity of the emissions. Changes in biological systems may be induced that are not attributable to blast, heat, or single-type radiation effects. Many data and discussions have resulted from laboratory studies of radiations, but until recently scant infor...

The Induction of Recessive Lethals in Drosophila Melanogaster by Radiations of Different Ion Density.

ARLY investigators in radiation genetics claimed that X-rays of different wave E lengths, gamma rays, and beta particles of radium were equally effective in inducing sex-linked recessive mutations in Drosophila melanogaster and that densely ionizing radiations such as recoil protons from neutrons and alpha particles were less efficient than the less densely ionizing X, gamma, and beta radiation...
