| Abstract | ||
| In this study we mention one of the treatments to cure cancer. It is considered one of the promissing methods nowadays. It includes the use of Boron as a nano material to improve the radiation sensitivity inside the breast. These are treated with low energy thermal neutrons (0.025 eV) resulting in high alpha linear energy transporter and Lithium nucleus (_^7)Li in addition to Gamma photon with (0.48 MeV). The energy of these products (2.31 MeV) which destroy the cancer cells in the tissue. This treatment checks several physical factors related to the effectively of using Boron to improve the treatment with radiation. The physical factors include the amount of the falling thermal neutrons and the time of exposure and the concentration of the nano Boron material and the amount of the falling thermal neutrons. In this study the concentrations of used nano Boron were (5, 10, 15, 20, 25, 30, 35, 40, 45, 50) ng, and each concentration was a target for the thermal neutrons of (0.025 eV) energy interaction. The times of exposure (1800) s , while the other factors were kept fixed. The results showed a great improvement in the received dose and improvement in the number of the destroyed cancer cells. The increase is due to two reasons: First : the selective accumulation of stable(_^10)B in the cells of the tumor only and not the healthy tissue. Second : (_^10)B tendency towards thermal neutrons (0.025 eV) interaction. The resultant from this interaction is unstable (_^11)B causing the production of high linear energy transporter represented by alpha particle ( 1.47 MeV) and (_^7)Li nucleus (0.84 MeV), as well as Gamma photon (0.48 MeV). The energy of both products is deposited within (5-9 µm) of the tissue which is close to the cells diameter and it spreads in two opposite directions in destroying the DNA chain responsible for regenerating new cells, therefore, the possibility of destroying cancer cells is high. | ||
