Abstract
The invention provides a kind of radon measuring devices, including measuring probe and measuring instrument, the measuring probe is popped one's head in be cylindric, is air intake at top end opening, and porch sets air exhauster；Probe is internal to be set one-level radon measuring point, two level radon measuring point under upper and is connected to measuring instrument sheet by flexible pipe with three-level radon measuring point, probe bottom.The measuring instrument high sensitivity of invention, characteristic of energy response is good, the radon contents detection in air can be carried out, it using air suction type measuring probe, can improve to the radon contents measurement efficiency in air, and relatively be measured using multistage, the accuracy of measurement can be improved, meanwhile the measuring instrument small volume, numerical monitor close rate state are more directly perceived.
Description
Technical field
The present invention relates to nuclear radiation detection field, more particularly to a kind of radon measuring devices.
Background technology
Radon be also cause resident's lung cancer occur the reason for one of, be the second largest factor for being only second to Induced By Tobacco Smoke lung cancer.Closely
For over ten years, the World Health Organization announce people suffered by natural radiation in 50% be as caused by the radon gas in environment, therefore
The measure of radon gas has been increasingly becoming the topic of public concern at present.Fully understand that instrument for measuring radon species, principle and application are also people
Focus more on.
As China's expanding economy, the improvement of house condition, environment radon problem are more and more prominent.Opened from nineteen ninety-five
Begin, China promulgates in succession《Radon consistence controls standard in house》(GB/T16146-1995)、《Hypogee radon and radon daughter control
Standard processed》(GB 16356-1996)、《Code for indoor environmental pollution control of civil building engineering》(GB 50325-2001)、《Build
Build material radionuclide limitation》(GB 6566-2001)、《Indoor Air Quality standards》(GB/T 18883-2002) and《Electricity
From radiation protection and the safe basic standard of radiation source》(GB 18870-2002) etc. controls the national standard of radon, in room and ground
Radon consistence level in lower building is intervened.So as to promote the measurement of radon and radon daughter in surrounding air and control obtained it is fast
The development of speed, various new measuring methods and instrument are exploited.It is to be understood that whether the radon consistence in room is exceeded, it is just necessary
Carry out the Accurate Determining of radon consistence.Mainly determine radon consistence by emanometer at this stage.
The content of the invention
In order to solve the above technical problems, one aspect of the present invention is：A kind of radon measuring devices are provided, it is special
Sign is：Measuring probe and measuring instrument；
The measuring probe is popped one's head in be cylindric, is air intake at top end opening, and porch sets air exhauster；In probe
Portion sets one-level radon measuring point, two level radon measuring point under upper and is connected to measurement by flexible pipe with three-level radon measuring point, probe bottom
Instrument；
Include the comparator being sequentially connected inside the measuring instrument, digital signal processor DSP and processor, processor are defeated
Go out detecting structure to display device.
Preferably, a photomultiplier is connected respectively after described every one-level radon measuring point, amplified by photomultiplier
Measurement signal carries out Digital Signal Processing after being then compared.
Preferably, the measuring instrument is open type measuring instrument, and display device is arranged at measuring instrument and covered.
The situation of prior art is different from, the beneficial effects of the invention are as follows：
1st, the measuring instrument high sensitivity, characteristic of energy response is good, can operate with medical treatment and completion, nuclear submarine, nuclear power station
Deng the region that dose of radiation is larger.
2nd, the measuring instrument small volume, numerical monitor close rate state are more directly perceived.
3rd, the measuring instrument uses air suction type measuring probe, can improve to the radon contents measurement efficiency in air, and adopt
Relatively measured with multistage, the accuracy of measurement can be improved.
Brief description of the drawings
Fig. 1 is the structural representation of radon measuring devices of the embodiment of the present invention.
Fig. 2 is the fundamental diagram of radon measuring devices of the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only the part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
A kind of radon measuring devices are provided, as shown in Figure 1：Including measuring probe and measuring instrument；
The measuring probe is popped one's head in be cylindric, is air intake at top end opening, and porch sets air exhauster；In probe
Portion sets one-level radon measuring point, two level radon measuring point under upper and is connected to measurement by flexible pipe with three-level radon measuring point, probe bottom
Instrument；
Include the comparator being sequentially connected inside the measuring instrument, digital signal processor DSP and processor, processor are defeated
Go out detecting structure to display device.
Specifically, a photomultiplier is connected respectively after described every one-level radon measuring point, put by photomultiplier
Big measurement signal carries out Digital Signal Processing after being then compared.
Preferably, the measuring instrument is open type measuring instrument, display device is arranged at measuring instrument and covered.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
