Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of embodiment of core haze measurement mechanism of the present invention.
Embodiment
The invention discloses a kind of structure simple and core haze measurement mechanism and the method for outdoor measurement operation can be supported.
As shown in Figure 1, core haze measurement mechanism disclosed by the invention, in order to measure in the tested point 100 of outdoor.Described core haze measurement mechanism comprises the first box body 200, be arranged in the first box body 200 in order to measure background radiation amount the first radiation detector 300 and be positioned at outside the first box body 200 in order to measure tested point radiant quantity and background radiation amount and the second radiation detector 400.For vacuum environment or be provided with the medium being different from air to be measured in described first box body 200, described second radiation detector 400 directly contacts with the air in tested point 100.Measure acquisition one first data group by described first radiation detector 300, measure acquisition one second data group by described second radiation detector 400, by carrying out the first data group and the second data group processing the radiant quantity obtaining tested point.When there is no energy information, can adopt to the counting of same time the radiant quantity directly method that two groups of data are subtracted each other being obtained tested point.When there being energy information, can obtain histogram respectively to two groups of data, then the radiant quantity obtaining tested point is subtracted each other in histogram alignment.Certainly, when there being energy information, the mode that above-mentioned same time counting also can be adopted directly to subtract each other obtains the radiant quantity of tested point.
Described medium preferably selects cold medium.Described tested point radiant quantity can not be detected through medium or vacuum environment by the first radiation detector 300, or the tested point radiant quantity that detects of the first radiation detector can be left in the basket and disregards.The present invention can control by the distance of the size or increase box and tested point that increase box the information whether the first radiation detector can detect tested point radiant quantity.Box size increases, and namely vacuum environment is large or media environment is large.Box and arranging of medium all change flexibly according to the actual conditions of the radiant quantity of tested point, as long as can ensure that the first radiation detector 300 can not detect the radiant quantity of tested point, or the first radiation detector 300 can only detect the radiant quantity of some tested points, this radiant quantity energy is uncared-for or do not have an impact to whole measurement result.
In order to ensure accuracy and the operation convenience of measurement, that generally the first radiation detector 300 and the second radiation detector 400 can be placed is closer, and the radiant quantity in order to the second radiation detector 400 can be allowed can to detect tested point accurately, in the negligible situation of tested point radiant quantity that the first radiation detector detects, can near some tested points.
Bee-line scope between described first box body 200 and the first radiation detector 300 is 0.1m ~ 100m.Concrete selection is determined according to the actual conditions of tested point, conveniently record, generally can select 1m, 10m, 20m, 30m, 40m, 50m, 60m, 70m, 80m, 90m, 100m.
First box body 200 can be arranged to collapsed shape, or the first box body 200 of sizes scope is set, it is no matter the first box body 200 of which kind of form or which kind of size, purport is after evacuation or after being filled with medium, the first radiation detector 300 can be allowed to measure background radiation (background radiation refers to the radiation deriving from radioactive particle in universe detected), and allow the first radiation detector 300 not detect or the radiation of small tested point can only be measured.
As shown in Figure 1, the first box portion outside is located at by the second radiation detector 400, and certain second radiation detector 400 also directly can be located at any position on the first box body.When the first box portion outside is located at by the second radiation detector 400, the bee-line scope between the second radiation detector 400 and the lateral surface of the first box body 200 is 0.1m ~ 100m.Concrete selection is determined according to the actual conditions of tested point, conveniently record, generally can select 1m, 10m, 20m, 30m, 40m, 50m, 60m, 70m, 80m, 90m, 100m.Arranging of this distance reasonably can set with reference to the bee-line between the first box body 200 and the first radiation detector 300.
If considered from the angle of protection second radiation detector 400, can certainly arrange one in order to place the second box body of the second radiation detector, the bee-line scope between the lateral surface of the first box body 200 and the lateral surface of the second box body is 0.1m ~ 100m.Concrete selection is determined according to the actual conditions of tested point, conveniently record, generally can select 1m, 10m, 20m, 30m, 40m, 50m, 60m, 70m, 80m, 90m, 100m.Arranging of this distance reasonably can set with reference to the bee-line between the first box body 200 and the first radiation detector 300 equally.
The described medium adopted in core haze measurement mechanism of the present invention can be pure air or nitrogen or oil or other gases etc.Select which kind of medium not by aforesaid restriction, as long as the medium selected by ensureing is not containing radioactivity, or the radioactivity contained is faint, or the radioactivity contained is can quantum chemical method all passable.Setting like this is to prevent the result the first radiation detector 300 being measured to background radiation from causing unnecessary interference, conveniently obtaining tested point radiant quantity accurately.
So in order to reach best measurement effect, core haze measurement mechanism of the present invention also comprises vacuum extractor.
The present invention is in principle when the first box body 200 is not when adopting the state that vacuumizes to measure, the material of the first box body is not limited, as long as ensure that the first box body does not stop that background radiation measured by the first radiation detector 300, or can not stop that background radiation measured by too many first radiation detector 300.If the first box body 200 adopts to vacuumize state and measure, required by so having the material of the first box body 200, mainly wish that this material can isolate the air of extraneous tested point.
Detectable signal is transferred to a data Graphics Processing terminal by wired or wireless function by the first radiation detector 300 and the second radiation detector 400.
When needs to tested point compare comprehensively measure time, some groups can be arranged with structure and identical the first box body, the first radiation detector, the second radiation detector of arrangement mode.Some groups of data can be drawn like this, facilitate data to carry out correction process, obtain result the most accurately.And the data obtained can be used as other purposes, such as do regional radiant quantity distributional analysis etc.Can also by arranging structure of the present invention in a lot of area, can be real-time know and compare the development of the radiation information in each area, is convenient to do deep analytical work and later stage environmental planning work.
The present invention is by arranging two radiation detectors, wherein the first radiation detector 300 can measure background radiation amount, second radiation detector 400 can measure tested point radiant quantity and background radiation amount and, then can obtain the radiant quantity of tested point by carrying out process to two groups of measurement data.
