<p><strong>Abstract</strong> Cancer is a deadly disease that exist on planet earth. Efforts were made to be able to kill cancer cells either by manual operation or by radiotherapy. One way to use energy radiation radioactive elements as killers of cancer cells is Boron Neutron Capture Therapy (BNCT). BNCT is a therapeutic technique that utilizes the interaction of neutron capture by the core 10B will produce α-particles and nuclei 7Li results by reaction 10B (n, α) 7Li. It therefore requires a material that will produce neutrons used in BNCT. Materials  target that will be searched in order to obtain optimal materials according to the requirements provided by the International Atomic Agency (IAEA).<em></em></p><p><em> </em></p><p><strong>Keywords </strong>: Kanker, Material, Neutron, BNCT</p><p align="center"><strong><em> </em></strong></p><p><strong>Abstrak</strong> Kanker adalah salah satu penyakit yang mematikan yang ada di planet bumi.

For a large number of women who are diagnosed with breast cancer every year the avail able treatment options are effective, though physically and mentally taxing. This work is a starting point of a study of the efficacy of boron neutron capture therapy as an alternative treatment for HER-2+ breast tumors. Using HER-2-specific monoclonal anti bodies coupled with a boron-rich oligomeric phosphate diester, it may be possible to deliver sufficient amounts of 10B to a tumor of the breast to al low for selective cell destruction via irradiation by thermal neutrons. A comprehensive computational model (MCNP) for thermal neutron irradiation of the breast is described, as well as the results of calculations made using this model, in order to determine the optimum boron concentration within the tumor for an effective boron neutron capture therapy treatment, as compared with traditional X-ray radiotherapy. The results indicate that a boron concentration of 50-60 mg per gram of tumor tissue is optimal when considering treatment times, dose distributions and skin sparing. How ever these results are based upon best-guess assumptions that must be experimentally verified.

 The direct and indirect ionizing radiation sources for boron neutron capture therapy (BNCT)are identi?ed. The mechanisms of physical, chemical and biological radiation interactions for BNCT are systematically described and analyzed. The relationship between the effect of biological radiation and radiation dose are illustrated and analyzed for BNCT. If the DNAs in chromosomes are damaged by ion- izing radiations, the instructions that control the cell function and reproduction are also damaged. This radiation damage may be reparable, irreparable, or incorrectly repaired. The irreparable damage can result in cell death at next mitosis while incorrectly repaired damage can result in mutation. Cell death leads to variable degrees of tissue dysfunction, which can affect the whole organism’s functions. Can- cer cells cannot live without oxygen and nutrients via the blood supply. A cancer tumor can be shrunk by damaging angiogenic factors and/or capillaries via ionizing radiations to decrease blood supply into the cancer tumor. The collisions between ionizing radiations and the target nuclei and the absorption of the ultraviolet, visible light, infrared and microwaves from bremsstrahlung in the tumor can heat up and damage cancer cells and function as thermotherapy. The cancer cells are more chemically and biologically sensitive at the BNCT-induced higher temperatures since free-radical-induced chemical re- actions are more random and vigorous at higher temperatures after irradiation, and consequently the cancer cells are harder to divide or even survive due to more cell DNA damage. BNCT is demonstrated via a recent clinical trial that it is quite effective in treating recurrent nasopharyngeal cancer.
