Multifunctional rare earth product radioactivity detecting instrument based on composite detector

Abstract

The invention discloses a multifunctional rare earth product radioactivity detecting instrument based on a composite detector. The instrument can be used for the radioactivity monitoring of the rare earth product, and comprises a composite detector, a signal conditioning module, a lead chamber, a multi-channel data collecting and analyzing module, a computer data analyzing and managing module, a power supply managing module with low power consumption, and the like, wherein the composite detector is formed by combing a detector for detecting alpha and beta total amount and a detector for detecting gamma energy spectrum into a whole. The instrument can be used for simultaneously measuring the alpha and beta total amount and the gamma energy spectrum, and can give the alpha and beta total amount and the contents of radium, uranium, thorium, potassium and rate earth self radioactive element through one-time measurement. The instrument can realize the function which is realized by several instruments and several measurements in the prior art through one-time measurement. The invention has broad applying prospect in the radioactivity detecting field of rare earth industry, and has the advantages of simple and reasonable structure, high price / performance ratio, low energy consumption, strong function, convenient use and the like.

Description

technical field [0001] The invention relates to a multi-functional radioactivity detector for rare earth products based on a composite detector. A multifunctional radioactive detector for rare earth products based on composite detectors for degree analysis. Background technique [0002] Rare earth is a valuable strategic resource, known as "industrial monosodium glutamate" and "mother of new materials", and is widely used in cutting-edge technology and military fields. After nearly 60 years of scientific and technological research and development and construction, my country's rare earth industry has made remarkable achievements, and has become the world's largest rare earth resource, production, application and exporter. [0003] Due to the difference in the origin of rare earth raw materials, the level of sample purity, and the difference in rare earth deep processing technology, the types of radionuclides mixed in rare earth products are also different. Therefore, the ra...
