Embodiment Construction

[0070] Further description will be given below in conjunction with the accompanying drawings and embodiments.

[0071] ①The requirements for each component are as follows:

[0072] ◇ As shown in Figure 2, adjust the center radiation line of the two gamma sources 2.1 in the YY' direction, adjust the ZT direction of the finger body positioner 3 in the XX' direction, and the XX' direction and the YY' direction are orthogonal to 0 point; make the index finger big The joint is at 0 point; the central axis of the probe 4.1 is in the ZZ' direction, and the ZZ' direction passes through 0 point and is perpendicular to the XY plane.

[0073] ◇As shown in Figure 3, in the radiator 2, two gamma sources 2.1 are selected, the source strength is 2×2GBq, the diameter is φ3.0mm, and the thickness is 3.0mm.

[0074] The metal cavity 2.2 has a thickness of 3.0mm, an inner diameter of φ3.2mm, and a height of 3.2mm; a 0.5mm thick copper sheet is arranged in front of it as a filter plate to absorb...

Abstract

A method for measuring the Pb density of human finger bone without wound includes such steps as stimulating the information about Pb content in finger bone, detecting the released characteristic X-ray, processing the photoelectronic signals, and analyzing, displaying and outputting the Pb density value. Its apparatus is composed of irradiation platform, finger locator in X direction, two radiators in Y direction, detector in Z direction, controller, multi-channel analyzer and output device.

Description

technical field [0001] The invention relates to an in vitro direct measurement technology of heavy metal elements in human bones; in particular, it relates to a rapid and non-invasive method and device for measuring the content of lead elements in human index finger bones. Specifically, it is a technology that radioactively activates the lead element in the human body to cause it to release characteristic X-ray fluorescence, and then detects the X-ray fluorescence in vitro to determine the content of lead element in the body. The technique is called in vivo X-ray fluorescence analysis (In vivo XRF). Background technique [0002] Lead is the first heavy metal trace element that human beings are seriously poisoned by industrial and environmental pollution. Excessive lead accumulation in the human body will seriously cause various diseases of the human body, such as causing lesions in the nervous system, hematopoietic system, endocrine system and reproductive system; destroyin...
