- W4387156686 abstract "Texas Tech University submitted a request for a product line of neutron generators that is available through Thermo Fisher Scientific capable of producing 14$unicode{x2013}$MeV neutrons, specifically the P385 model that generates approximately 3x$10^{ 8}$ n/s as an isotropic source. To comply with the regulations set by the United States Nuclear Regulatory Commission, State of Texas Radiation, and Texas Tech radiation committee, adequate shielding is necessary to ensure that the radiation dose rates outside the walls of the containment building are below the prescribed levels. Typically, the neutron source needs to be shielded such that the radiation dose rate outside of the containment building is less than 0.25 mRem/hr (500mrem/2000 hour work-year). To address this requirement, we investigate the effectiveness of boronated concrete, boronated water, and light water shielding materials and their applicability to three neutron sources. We present our findings on the radiation shielding design and calculations for three neutron sources situated inside shielding layers. Our modeling utilized the Monte Carlo n$unicode{x2013}$Particle transport codes (MCNP6.2) to simulate neutron attenuation of the shielding. The simulation results reveal that a light water shielding can sufficiently reduce the dose rate for an individual located as close as two meters from the source. Therefore, this shield design can effectively decrease the radiation dose below the maximum recommended limit." @default.
