| titleOfInvention | A Semi-Physical Simulation Method for 3D Radiation Dose Fields Containing Strong Radioactive Sources |
| abstract | A semi-physical simulation method for a three-dimensional radiation dose field containing a strong radioactive source, using a solid structural structure to carry out geometric modeling and material modeling of the radioactive source and surrounding cladding structures, and setting the radioactive source according to the physical characteristics of the radionuclide ; Then, by reducing the density of the solid structure in the model, the global reference distribution of the three-dimensional radiation dose field is obtained, and the importance parameters are calculated based on the global reference distribution; then the density of the solid structure is gradually increased, and a full-reduced variance simulation is performed based on the importance parameters. , obtain the global asymptotic distribution of the three-dimensional radiation dose field; finally, combine the global reference distribution and the global asymptotic distribution to calculate the global approximate distribution of the three-dimensional radiation dose field under the condition of true density, and then set the importance parameters and perform the Mon-card calculation to get Obtain the 3D radiation dose field distribution under true density conditions. The invention can effectively improve the efficiency of the mask shielding calculation, realize the efficient and accurate semi-physical simulation of the real physical model, and thus improve the safety and controllability of the radiation source processing. |
