Design method of composite element model of aerial radioactivity measurement main standard device

Abstract

The invention provides a design method of a composite element model of an aerial radioactivity measurement main standard device and relates to the field of standard device design. The method comprisesthe composite element model, wherein the composite element model comprises thorium ore powder, uranium ore powder, potassium feldspar, potassic salt ore, cement and water. The design method comprisesthe steps of obtaining the mass percentage content of a potassium element, a thorium element and a uranium element in each material and the target mass percentage content of the potassium element, the thorium element and the uranium element in each material, determining the mass of the uranium ore powder, the thorium ore powder, the potassic salt ore and the potassium feldspar according to a preset algorithm, and further determining the proportion of the uranium ore powder to the thorium ore powder to the potassic salt ore to the potassium feldspar. The proportion is recorded, so that the proportion of important compositions is accurately calculated according to actual demands, guidance is provided for follow-up research and design, and later main standard device model design is facilitated.

Description

technical field [0001] The invention relates to the field of standard device design, in particular to a design method for a composite element model of a main standard device for aviation radioactivity measurement. Background technique [0002] The main standard model of aviation radioactivity measurement is the measurement standard of aviation radioactivity measurement. Indispensable infrastructure. [0003] The existing master standard model for airborne radioactivity measurement was built in 1986. Limited by the development of science and technology at that time, the single model area of ​​the master standard model covers an area of ​​127.3m 2 , with a weight of 140t, is fixedly placed at Daguo Village Airport in Shijiazhuang, and is the only national defense and national measurement standard equipment for aviation radioactivity measurement. At the same time, due to the long construction time, the design method and content of the master standard model were incomplete at ...
