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 water body radon contents measurement is provided
Instrument, it is characterised in that：Including detection container and measuring instrument；

Inner lead connecting detection probe, PH detector and salt bridge barrier film.
Include the comparator being sequentially connected, digital signal processor DSP and processor, processor inside the detection container
Detecting structure is exported to display device.
Preferably, the measuring probe is popped one's head in for column, and some permeable holes are set on cylinder of popping one's head in, set radon to survey in hole
Point；Probe upper and lower ends are fixed on above and below detection container between inwall；The measuring probe is in the same section in detection container inner chamber
Upper spaced set several.
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 display device uses waterproofing design, prevents the detection means from soaking under water and causing equipment
Failure.
Preferably, the measuring instrument is open type measuring instrument, and display device is arranged at measuring instrument and covered.
Preferably, be additionally provided with suction hose inside the detection container, the suction hose can external tank, for taking out
Part water sample is taken to carry out the more accurate detection in later stage.
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, using cavity type measuring instrument, the radon contents of water body can be detected in real time, at the same set salt bridge barrier film and
PH detection means can synchronize measurement to water quality.
