Radioactive solid waste detection and classification system

Abstract

The invention belongs to the technical field of solid waste treatment, and discloses a radioactive solid waste detection and classification system. The radioactive solid waste detection and classification system comprises a sample pretreatment module, a perspective imaging module, a central control module, a scanning measurement module, a measurement result correction module, a solid waste detection and classification module, an evaluation module, a data storage module and an update display module. According to the system, the corresponding relation between the radioactive solid waste pollution level and the surface dose level limit range is established, the radioactive solid waste surface dose level is compared with the surface dose level limit range, the pollution level is rapidly determined, classified collection is achieved, therefore, the treatment, disposal and management capabilities of the solid radioactive wastes are greatly improved. The system is closer to the field actual situation, field implementation is facilitated, the evaluation result is more credible, the composition and activity of the radionuclide in the waste bag can be obtained through analysis and evaluation, and the related requirements of radioactive waste treatment are met.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, in particular to a radioactive solid waste detection and classification system. Background technique [0002] At present, radioactive solid waste mainly exists in nuclear power plants, decommissioned nuclear facilities and contaminated soil. According to the degree of pollution, it is mainly divided into exempt waste, low-level waste, intermediate-level waste, high-level waste and alpha waste. Wastes of different contamination levels require different treatment and disposal methods, so radioactive solid waste is collected and classified. Preprocessing has become a very important part of the processing. [0003] However, in the current domestic nuclear facility decommissioning and waste treatment and disposal activities, there is no corresponding reference technical standard for the pretreatment process of radioactive solid waste, although in this process, radiation monitors will u...
