Description
Technical field
The utility model is related to X-ray Testing Technology field, more particularly to a kind of new x-ray detection device.
Background technology
At present, the radiotherapy apparatus of hospital or other detection devices can produce X-ray in use, although these set
There are certain safeguard procedures, but because the penetrability of X-ray is stronger, has a small amount of X-ray pierce through the protection barrier and enter
Operating personnel and other external staff are easily caused certain injury by outside, and the instrument of existing sensing and measurement X-ray
All select expensive material and device, therefore the place influenceed at some by objective factors such as funds, be badly in need of it is a kind of it is low into
Originally, x-ray detection device simple and easy to apply.
Utility model content
The utility model is penetrated to make up the defect of prior art there is provided a kind of new X simple in construction, reasonable in design
Line detector.
The utility model is achieved by the following technical solution：
A kind of new x-ray detection device, it is characterised in that：Housing including closing, the inner walls are provided with increasing
Sense screen, enclosure interior is provided with phototriode, and the forward end connection of the phototriode and differential comparator is also associated with
External power supply, other end connection divider resistance, the differential comparator negative end is connected with slide rheostat, the connection of its output end
Light emitting diode, light emitting diode is located at the outside of housing, and pull-up is connected between the light emitting diode and slide rheostat
Resistance circuit.
The material of the housing is radiation-sensitive materials, can be with the extraneous faint X-ray of effectively perceive, for reminding people
Away from radiation.
The intensifying screen is rare earth intensifying screen, using the fluorescent effect of X-ray, rare earth intensifying screen is sent fluorescence, fluorescence
It is irradiated on phototriode.
The pull-up resistor circuit includes first resistor and external power supply.
The phototriode is 3DU33 types.
The differential comparator is LM393P.
The beneficial effects of the utility model are：The new x-ray detection device, it is simple in construction, and material and device cost
Relatively low so that radioinduction and the cost of measurement are substantially reduced, energy actual induction X-ray simultaneously makes light warning, can be effective
The presence of people's ionising radiation is reminded, is suitably promoted the use of.
Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing 1 is electrical block diagram of the present utility model.
In figure, 1, phototriode, 2, divider resistance, 3, differential comparator, 4, slide rheostat, 5, first resistor, 6 hairs
Optical diode, 7 external power supplys I, 8 external power supplys II.
Embodiment
Accompanying drawing 1 is a kind of specific embodiment of the present utility model.Accompanying drawing 1 show its circuit structure diagram, the new X-ray
Detection means, includes the housing of closing, and the inner walls are provided with rare earth intensifying screen, using the fluorescent effect of X-ray, made dilute
Native intensifying screen sends fluorescence, and enclosure interior is provided with 3DU33 types phototriode 1, phototriode 1 and LM393P type differential ratios
Forward end compared with device 3 is connected, and one end of phototriode 1 is also connected with external power supply I 7, while the other end connects divider resistance
2, the negative end of the differential comparator 3 is connected with slide rheostat 4, its output end connecting luminous diode 6, light emitting diode
6 are located at the outside of housing, and pull-up resistor circuit, pull-up resistor electricity are connected between the light emitting diode 6 and slide rheostat 5
Road includes first resistor 5 and external power supply II 8.
X-ray detection device of the present utility model, the material of housing is radiation-sensitive materials, can be micro- with the effectively perceive external world
Weak X-ray, when in x-ray bombardment to housing, the inwall of housing can fluoresce due to rare earth intensifying screen inwardly, and fluorescence shines
Phototriode 1 is mapped to, then the electric current in circuit can change, the change of electric current causes differential comparator 3 to turn on, so that
There is light warning in the light emitting diode 6 that hull outside must be located at, for reminding people away from radiation.It is simple in construction, and material
And device cost is relatively low so that radioinduction and the cost of measurement are substantially reduced, energy actual induction X-ray simultaneously makes light police
Show, can effectively remind the presence of people's ionising radiation, suitably promote the use of.
