Reverse Monte Carlo particle transporting and simulating system

Abstract

The invention provides a reverse Monte Carlo particle transporting and simulating system. According to a designed object or an external measuring result, and via direct reverse Monte Carlo simulating and particle transporting principle, three-dimensional transporting process and radioactive source information of radioactive intermediate particles are obtained. The reverse Monte Carlo particle transporting and simulating system comprises a state parameter and sequence inputting and processing module, an automatic modeling module, a reverse moving process simulating module, a result recording and error computing module, and a database managing module. Conventional Monte Carlo particle transporting and simulating are performed via a forward simulating method and belong to direct result simulating process according to direct reasons. In actual situation, in order to reproduce inputting or intermediate processes of the particle transportation, above information can be obtained via the reverse Monte Carlo particle transporting and simulating system. The reverse Monte Carlo particle transporting and simulating system has the advantage that intermediate and staring processes of three-dimensional particle transport is reversely simulated according to the target result, and precise simulating data for part designing, computing and optimizing of radiation dosage of a human body, breeding irradiating and the like about a nuclear device are provided.

Description

technical field [0001] The invention relates to a reverse Monte Carlo (MC) particle transport simulation system, which belongs to the particle transport simulation direction in multidisciplinary interdisciplinary fields such as nuclear science and engineering, radiation protection and environmental protection, and nuclear technology application. Background technique [0002] In the development of equipment related to particle transport simulation systems in the past, the existing Monte Carlo particle transport simulation system uses forward simulation technology, which belongs to the process of directly simulating the results according to the cause. The existing Monte Carlo simulation systems include: EGS4, FLUKA, ETRAN, ITS, MCNP, GEANT, etc. Classified from the simulation of electron and photon transport, these systems can be divided into two series: (1) EGS4, FLUKA, GRANT; (2) ETRAN, ITS, MCNP. The difference between these two series is that the simulation of the electro...
