Description
Technical field
This utility model relates to gamma detection technique field, particularly relates to a kind of gamma-ray energy spectrum
Instrument.
Background technology
Carrying out relatively low level of activity's gamma-ray spectrometry analysis, energy disperse spectroscopy and analysans are required to be placed in gal
In agate ray shielding device, to reduce the impact of surrounding gamma ray, screening arrangement is generally adopted
Using vitriol chamber shield, vitriol chamber shield weight and volume is the biggest, when Environmental emergency monitoring, and fortune
Defeated, mobile the most very inconvenient.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of gamma-ray energy spectrum instrument, it is possible to
It is readily transported and moves, the demand of emergency monitoring or field monitoring can be met.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide one
Plant gamma-ray energy spectrum instrument, including probe body, storage container and analyzer, described probe body
Including protection shell and in described protection shell incident direction along gamma ray be sequentially placed
Photomultiplier tube array, optical fiber array, scintillation crystal array, described scintillation crystal array defeated
Going out end to be connected with analyzer, described storage container is fixed with described protection shell, and storage container is tight
Adjacent described photomultiplier tube array is arranged, and described storage container is used for holding analysans, described Sheng
Being loaded with lead protection material in container, wherein, analysans is enclosed in described lead protection material,
To shield the gamma ray in described analysans surrounding.
Preferably, the area of the exit end of described photomultiplier tube array is less than the face of incidence end
Long-pending.
Being different from the situation of prior art, the beneficial effects of the utility model are: contained by employing
There is the storage container of lead protection material to hold analysans, analysans surrounding can be shielded
In gamma ray, it is achieved measuring accurately, meanwhile, the weight and volume of storage container can do
Obtain the least, it is possible to be readily transported and move, the demand of emergency monitoring or field monitoring can be met.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment gamma-ray energy spectrum instrument.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, in this utility model embodiment
Technical scheme is clearly and completely described, it is clear that described embodiment is only that this practicality is new
A part of embodiment of type rather than whole embodiments.Based on the embodiment in this utility model,
It is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of this utility model protection.
See Fig. 1, be the structural representation of this utility model embodiment gamma-ray energy spectrum instrument.This
The gamma-ray energy spectrum instrument of embodiment includes probe body 1, storage container 2 and analyzer 3, visits
Head main body 1 includes protecting shell 11 and along the incident direction of gamma ray in protection shell 11
The photomultiplier tube array 12 that is sequentially placed, optical fiber array 13, scintillation crystal array 14, flicker
The outfan of crystal array 14 is connected with analyzer 3, and storage container 2 is fixed with protection shell 11,
And storage container 2 is close to photomultiplier tube array 12 and arranges, storage container 2 is used for holding to be treated point
Analysis thing, contains lead protection material 21 in storage container 2, wherein, analysans is enclosed in lead protection
In material 21, to shield the gamma ray in analysans surrounding.In the present embodiment,
The area of the exit end of photomultiplier tube array 12 is less than the area of incidence end, and exit end is face
To the end of optical fiber array 13, incidence end is the end of the incident direction towards gamma ray.
Gamma ray is converted into visible ray, optical fiber array 13 guiding by photomultiplier tube array 12
The effect of light, visible ray is converted into the signal of telecommunication by scintillation crystal array 14, and analyzer 3 is to reception
To the signal of telecommunication process after output spectrum information.
If being analysed to thing and being exposed to time air measures, from surface rock, soil,
The gamma ray that radionuclide in Adjacent Buildings and air produces can affect accuracy of detection and
Detection limit, and it is analysed to thing when being placed in lead protection material 21, the gamma ray in environment exists
After lead material, major part ray can be absorbed.And that storage container 2 can do is the least, weight
Amount and volume can be controlled.
By the way, the gamma-ray energy spectrum instrument of this utility model embodiment is contained by employing
There is the storage container of lead protection material to hold analysans, analysans surrounding can be shielded
In gamma ray, it is achieved measuring accurately, meanwhile, the weight and volume of storage container can do
Obtain the least, it is possible to be readily transported and move, the demand of emergency monitoring or field monitoring can be met.
The foregoing is only embodiment of the present utility model, not thereby limit of the present utility model specially
Profit scope, every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence
Flow process converts, or is directly or indirectly used in other relevant technical fields, is the most in like manner included in this
In the scope of patent protection of utility model.
