Abstract

The invention provides a device for simulating the radionuclide wet deposition. The device comprises a rainfall artificial climate chamber, a contaminated water tank connected with the rainfall artificial climate chamber through a water distribution pipeline of a rainfall system, and an automatic control and monitoring system electrically connected with the rainfall artificial climate chamber; therainfall artificial climate chamber comprises a rainfall system, a temperature and humidity regulating system, a fresh air system, a light source system and a CO2 concentration regulating system, anda seedbed and experimental plants are placed at the bottom of the rainfall artificial climate chamber. The device simulates and studies the influence process of changes of meteorological factors including temperature, humidity, CO2, light and the like and the complex climatic conditions of plant sites for migration of nuclides in a terrestrial ecosystem.

Description

technical field [0001] The invention belongs to the technical field of radiation ecology, and in particular relates to a device for simulating wet deposition of radionuclides. Background technique [0002] Radiation environmental impact assessment refers to the prediction and estimation of the possible impact of the use of a source or a practice on the environment, including an overview of the scale and characteristics of the source or practice, an analysis of the current situation of the site or site environment, and Analysis of possible environmental impacts or consequences under normal conditions and in accident situations. In the radiation environmental impact assessment of nuclear facilities, the ecological transfer parameters of radionuclides are important parameters for assessing the radiation dose to the public caused by the human food chain intake route. [0003] Radionuclides can be released from nuclear facilities into the terrestrial environment in the form of p...
