Description
Technical field
The utility model relates to scintillation crystal field, is specifically related to a kind of square combination crystal.
Background technology
Crystalline substance is owing to having various characteristic, so or the important materials of various technology, develop rapidly particularly in modern age due to new technology, require the crystalline material with various performance, no matter and the crystal that nature is contained is qualitatively, quantity and kind all can not meet needs, therefore scientist is with regard to the minerogentic condition of simulating nature circle, manual method is adopted to cultivate crystal, this is just called artificial lens, artificial lens is of a great variety, is day by day subject to large crystalloid a--scintillation crystal of people's favor in recent years.
When some solid matter of electron bombardment of high speed motion, a kind of invisible hertzian wave can be there is by Hong object, be called X-ray, it is no matter the tissue of human body, or the steel plate of a few cm thick, X-ray can be unblocked, therefore can be used to carry out medical diagnosis, industrial flaw detection and species analysis etc., but from the X-ray that X-ray tube sends, people are invisible, when it is irradiated on a window of tube and will sends fluorescence, such doctor just sees the situation of x-ray fluoroscopy human body, it is no problem that same quality inspector just can recognize that tested object internal soundness has, this window of tube just serves effect X-ray invisible to the human eye being transformed into observable light.These materials that can inspire fluorescence under X-ray irradiates are exactly scintillation crystal.Scintillation crystal can send except fluorescence under irradiating at X-ray, other energetic rays as radio isotope transformation generation are as alpha-ray, β radiation exposure it time also can send fluorescence, people utilize this characteristic of scintillation crystal to make the detector of the various ray of measurement, namely when energetic ray is irradiated to after on detector, scintillation crystal just sends fluorescence, ray is stronger, the fluorescence sent is stronger, this fluorescence is photoelectrically converted system acceptance be transformed into electrical signal, after electronic circuit process, just can indicate on the indicator, therefore this detector is likened to " eyes " of visible X-ray and other energetic rays by people.
Existing scintillation crystal is all the ray that can detect single wavelength, is difficult to the demand meeting existing technique, therefore needs one can detect gamma-rays, alpha-ray and β ray simultaneously
Utility model content
The purpose of this utility model is to provide a kind of good processing, cost is low, area is large square combination crystal, realizes detecting gamma-rays, alpha-ray and β ray simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
A kind of square combination scintillation crystal, comprise scintillation crystal, the shape of described scintillation crystal is the cuboid with six sides, one of them side is fixedly connected with polystyrene by tackiness agent, the outside of described polystyrene is provided with zinc sulphide or silver sulfide, the outside of described scintillation crystal is provided with crystal shell, and described crystal shell wraps up all the other five sides of described scintillation crystal.
Further, the shape of the side, side of described scintillation crystal is square.
Further, the Thickness Ratio of described polystyrene and silver sulfide is 10: 1.
Further, described scintillation crystal setting-in is located on described crystal shell.
Further, described scintillation crystal is the combination scintillation crystal of sodium iodide crystal and plastic scintillator.
The beneficial effects of the utility model are: the utility model can detect gamma-rays, alpha-ray and β ray simultaneously, and this apparatus structure is simple simultaneously, cost is low.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 be a kind of square combination scintillation crystal described in the utility model embodiment face structure iron;

The shape of described scintillation crystal is the cuboid with six sides, wherein the shape of side, side is square, this side, side is fixedly connected with polystyrene 5 by tackiness agent 4, for to beta-ray detection, the faint alpha-ray be entrained in β ray can be shielded simultaneously, the outside of described polystyrene 5 is provided with zinc sulphide 6 or silver sulfide, for to alpha detection, can shield the faint β ray be entrained in alpha-ray, described polystyrene 5 is 10: 1 with the Thickness Ratio of silver sulfide simultaneously.
The outside of described scintillation crystal is provided with crystal shell 3, and described crystal shell 3 wraps up removing on described scintillation crystal and is provided with all the other five sides of polystyrene 5, and described scintillation crystal setting-in is located on described crystal shell 3.
The utility model can reach 60% for alpha-ray and Beta-ray detection efficiency, and the counting for gamma ray can reach count per minute 70 per second, and such working efficiency can be competent at the requirement of experiment of laboratory and scientific research institutions thereof completely.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
