Problems solved by technology

However, since the nuclear industry system carried out uranium ore exploration work, the radioactive exploration instruments in my country's nuclear industry system, such as gamma logging tools, core loggers, and directional gamma radiation instruments, have all used radium sources for interim inspections. The decommissioning of radium sources has made The instruments in the field of uranium ore exploration cannot carry out interim verification, which brings difficulties to the continuation of uranium ore exploration

[0031] In the first embodiment, an embodiment of the present invention provides a uranium mine inspection device, comprising: a sealed casing and a cylindrical body, wherein a circular hole is provided in the center of the cylindrical body; the main body is arranged in the sealed casing;

[0032] like figure 1 As shown, the body consists of four verification points and five non-verification points; each verification point consists of a uranium-containing ore layer; each non-verification point consists of a uranium-free ore layer;

[0033] Both ends of the main body are non-check points, and at least one non-check point is included between any two check points.

[0034] Among them, the verification points are the first verification point, the second verification point, the third verification point and the fourth verification point set in sequence from one end of the main body to the other end;

[0035] The first verification point is composed of three layers of uranium-contain...

[0041] In a second embodiment, the present application provides an inspection device, comprising: four test points, the four test points are set in a low-content group and a high-content group, and both the low-content group and the high-content group include a sealed casing and a cylindrical main body, the center of the cylindrical main body is provided with a circular hole; the main body is arranged in the sealing shell;

[0042] like figure 2 As shown, the main body of the low-content group is two test points composed of two ore layers with different uranium content; the main body of the high-content group is two test points composed of two ore layers with different uranium content Test point; the height of the ore layer of one test point in the main body of the high-content group is 45cm, and the uranium content is 0.7671%; the height of the ore layer of the other test point is 35cm, and the uranium content is 3.35%.

[0043] like image 3 As shown, the uranium content ...

Abstract

The invention discloses a uranium ore inspection device, which belongs to the field of uranium ore exploration. It can simultaneously provide four test points for uranium-containing ore layers. and 1.0% average count rate of four grades of test points; and then achieve the equivalent uranium content range of quantitative γ parameters (0.01% ~ 1%) eU and the equivalent density range of γ-γ density parameters (1.05 ~ 2.30) g / cm 3 and other technical indicators. The verification device provided by the solution of the present application is light in weight and small in size, which improves the convenience and operability of field verification work and provides technical support for accurate and reliable field logging values.

Description

technical field [0001] The invention relates to the field of uranium ore exploration, in particular, to a uranium ore inspection device. Background technique [0002] In the field inspection of radioactive measuring instruments in the field of uranium resource exploration in my country, solid radium sources are used. During the use of the solid radium source, the fixed components may become loose, resulting in the displacement of the internal source tube, affecting the measurement accuracy; the solid radium source is made of pure radium salt powder welded and sealed in the source tube, especially the su To make radium source, radium salt is welded and sealed in glass tube, and most of them were produced in the 1960s. After more than 50 years of use, the high pressure caused by the accumulation of radon and helium generated by the bombardment and decay of high-energy gamma rays of radium, The damage of the source tube greatly increases the chance of scattering of radium salt...
