Problems solved by technology
[0005] In actual irradiation processing, the irradiation dose rate is also different due to the different densities of different irradiated products. Therefore, in the actual processing, the inventors are urged to study the influence of the radiation dose of products with different densities. The present invention provides a method for evaluating the influence of adjacent radiation of products with different densities on the dose rate, aiming at guiding different Density products are irradiated at the same time to save costs and improve irradiation efficiency

The invention relates to a method for evaluating an influence of adjacent irradiation of products with different densities on a dose rate. The method comprises the following steps of (1) setting a test irradiation route: setting the irradiation route according to test requirements, and arranging a unit test device to form the irradiation route; (2) carrying out MNCP analog calculation: calculatinga mutual influence between the densities of adjacent products and affected products through MNCP analog calculation; and (3) formulating an adjacent irradiation influence coefficient table of the products with the different densities according to an MNCP calculation result. The method is scientific and reasonable in design, the adjacent irradiation influence coefficient table of the products withthe different densities are formulated through a large number of actual test verification, guidance is provided for main control time setting and processing category determination of product irradiation, simultaneous irradiation processing of the products with the different densities is guided, and the method has important production practice research and development significance.
Description
technical field [0001] The invention belongs to the field of radiation processing, and relates to a radiation dose rate test, in particular to a method for evaluating the influence of adjacent radiation of products with different densities on the dose rate. Background technique [0002] Irradiation is a technology that uses the high energy and strong penetrating properties of ionizing radiation to sterilize, inhibit or promote growth, and change the properties of substances. The non-contact and cold processing environment provided by irradiation technology provides a solution for many , Heat-sensitive products provide a new way of purification, but also provide a new choice for the research and development of new materials and new energy. [0003] The irradiation sterilization process of food, medicine, agricultural products, etc. requires a complete quality control system. The quality control of irradiation processing, in addition to microbial detection and sensory properti...
