A kind of thermoluminescence card dosimeterTechnical field
The present invention relates to a kind of thermoluminescence card dosimeter in thermoluminescence Detection Techniques, belongs to radiation dose measurement technology neckDomain.
Background technology
Thermoluminescent detector (TLD) is a kind of solid-state dosimeter, have energy response is good, high sensitivity, dose response scope are wide,Measurement accuracy is high, in light weight, small volume and factor affected by environment are small, the characteristics of can surveying a variety of rays such as X, γ, β and neutron,Therefore it is widely used in the fields such as personal and environmental dose monitoring.
Thermoluminescent dosemeter can configure LiF：Mg, Cu, P or LiF：Mg, Ti thermoluminescent detector (TLD) (abbreviation detector), are used forThe monitoring of the deep dose of Radial-stricken Workers in Nuclear Industry, superficial dosage and eye lens dosage, its performance should meet national standard《It is personalWith environmental monitoring thermoluminescence dosimetry system》(GB10264-88) required as defined in.
At present two kinds of mode of heatings, the i.e. Hot-blast Heating (U.S. are used in external thermoluminescence self-operated measuring unit instrumentHarshaw companies) and infrared heating (MAT), and what the application proposed is electrically heated mode, it is domestic at present singlePassage reader is measured using electrical heating, the problems such as single measurement parameter, complex operation, speed are slow, are not easy to manage be present.The application using electrically heated mode indirectly (referring to《A kind of electrical heating card measurement of thermoluminescence heater》, utility model is specialSharp application number：201310051395.3), in the case where meeting measuring multiple parameters, solve heat in the prior art well and connectTouch the problem of bad.Can more quickly and accurately it provide by the dosimetric parameters according to personnel.
The content of the invention
The object of the invention is intended to overcome the deficiencies in the prior art and provides that analyze speed is fast, contains much information, be simple in construction, intoThis low, good thermoluminescence card dosimeter of performance, the measurement for X, γ, Beta-ray personal routine dose and accident dose.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：Thermoluminescence card dosimeter, including pallet, gland,Drain pan, location-plate, upper casing, coating film, detector, fixing rivet；
The beneficial effects of the invention are as follows：
Simple for structure reliable, assembling and setting is convenient, and the popularization to thermoluminescence technique has realistic meaning.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, the gland press fitting pallet is inlaid on location-plate.
Beneficial effect using above-mentioned further scheme is on the premise of mould-forming process is met, to ensure that assemblingPrecision, it is ensured that to pallet insulated heat.
Further, the location-plate is with passing through the overall integrated assembling of fixing rivet after drain pan, upper casing location and installation.
It is using the above-mentioned further beneficial effect of scheme, it is ensured that the uniformity and fastness of integral installation.
Further, the detector is placed on pallet, is encapsulated in by coating film on location-plate.
It is using the above-mentioned further beneficial effect of scheme, it is ensured that detector is easily assembled, waterproof and dampproof.
Further, the equal punch forming of drain pan and upper casing, the interior etching dosimeter information of upper casing upper surface deep gouge.
It is using the above-mentioned further beneficial effect of scheme, it is ensured that drain pan and upper casing assembly precision are good, whole after flow hardenBody intensity is high, is unlikely to deform.
Further, the location-plate uses high-temperature resistant polytetrafluoroethylmelt compression molding.
Further, the material of the coating film part is polyimides.
Further, the detector is sheet LiF：Mg, Cu, P detector or sheet LiF：Mg, Ti detector.
Further, the pallet is metal material.

Embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, the given examples are served only to explain the present invention, andIt is non-to be used to limit the scope of the present invention.
As shown in Figure 1, Figure 3, a kind of thermoluminescence card dosimeter, it is characterised in that：Including pallet 1, gland 2, drain pan 3,Location-plate 4, upper casing 5, coating film 6, detector 7, fixing rivet 8.
The gland 2 is pressed pallet 1 and is inlaid on location-plate 4.
The location-plate 4 is with passing through the overall integrated assembling of fixing rivet (8) after drain pan 3, the location and installation of upper casing 5
The detector 7 is placed on pallet 1, is encapsulated in by coating film 6 on location-plate 4.
The 5 equal punch forming of drain pan 3 and upper casing, the interior etching dosimeter information of the upper surface deep gouge of 3 upper casing of drain pan 5.
The location-plate 5 uses high-temperature resistant polytetrafluoroethylmelt compression molding.
The material of the part of coating film 6 is polyimides.
The detector 7 is sheet LiF：Mg, Cu, P detector or sheet LiF：Mg, Ti detector.
The pallet 1 is metal material.
It is as follows that the present invention is used for a kind of assembling principle of thermoluminescence card dosimeter：
First by pallet 1 on location-plate 4, install the molding assembly of gland 2 additional and be integrated；Placed in the groove of pallet 1Detector 7, upper surface covering coating film 6；Drain pan 3, upper casing 5 and location-plate 4 are assembled and fastening is connected by fixing rivet 8.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit andWithin principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
