Description
The present invention relates to a passive radon concentration detecting apparatus, and more particularly to a passive radon concentration detecting apparatus that remotely monitors the temperature, humidity, air pressure, airflow, illuminance, movement, And to a passive radon concentration detecting device for calibrating a measured value in consideration of environmental variables.
Radon (Rn) is a gaseous substance produced by radioactive decay of radium (Ra) in uranium and thorium radioactive series. It is colorless and odorless. It is inactive and has a high possibility of being easily inhaled to humans Big.
In the following description, the detection and the measurement are the same meaning, and it is selectively used in accordance with the context.
There are 2 to 4 ppm Uranium in the Earth's crust, with an average of 2.6 ppm Uranium, and Uranium 238, which accounts for 99.3% of the total uranium, has a half-life of 4.6 billion years. Uranium 238 undergoes natural decay through the half-life, transforming it into lead 206, transforming it into lead 206, generating radon 222, and radon 222 causing alpha to decay.
Underground radon is heavier than air but has the tendency to rise to the surface. Using these characteristics of radon, it can solve various geological problems such as uranium, geothermal and oil resource exploration, active fault detection, earthquake and volcanic eruption prediction It is used as an important tracer.
The radon rises toward the surface through interstices (faults, geological structure lines) depending on crustal movements and crustal movements, and is naturally highly detected in strata containing high uranium.
In order to investigate the radon content of the crust, the groundwater and groundwater are widely used. In the groundwater radon survey, 1) groundwater samples were taken from bore holes and analyzed by LSC (liquid scintillation counter) (2) A method of analyzing groundwater radar gas evacuated from groundwater using alpha cups in a well (borehole and synonym) (system and method for measuring radon gas for earthquake forecasting: Korean Patent Registration No. 10-0952657; 2010 . 04. 06.).
Analysis of radon content in groundwater gauges using water solubility, which is a characteristic of radon dissolving in water, is very useful for predicting underground resources (uranium, geothermal, petroleum) and geologic disasters (active faults, earthquakes, volcanic eruptions) .
Radon is the second leading cause of lung cancer, similar to smoking. Especially, even if the concentration of radium in the indoor air is very low, it can cause damage to the lungs due to radiation, and the radon is constantly caused by soil gas, building materials, There is a problem that it can flow into the indoor space and be distributed in any space on the earth.
Despite the serious problem of radon activity, it is hard to find a system to measure radon in a systematic way globally, and it relies only on the device to measure radon concentration sporadically.

Hereinafter, the NaI scintillation meter method, the gauge counter method and the alpha cup method will be described in detail.
1) NaI scintillation meter system
The NaI scintillation meter measures the amount of gamma rays using the photo-electric effect that occurs when gamma rays are absorbed in NaI or ZnS crystals treated with thallium. The principle of the scintillation meter is extended, and there is a gamma ray spectrometer, which estimates the decay factor of the emitted gamma ray by separately measuring the gamma ray by energy level.
NaI scintillation meters using fluorescence are generally used for detection of gamma rays. The gamma rays incident on the sensor emit fluorescence and are finally converted into electric pulses of a size corresponding to the energy through the photo-multiplier tube. It is the total gamma ray apparatus that counts the pulse signal many times, and the spectral method apparatus counts the magnitude (energy) of the pulse for each energy. The larger the diameter of the NaI crystal is, the higher the detection efficiency of the incident gamma ray and the higher the measurement accuracy of the sensor of the NaI scintillation meter.
Rock minerals within the earth emit radioactive isotopes that contain trace amounts. Among them, radiation detection is a method of detecting gamma rays, measuring the intensity (the number of radiation per unit time) or energy, and estimating the geological condition of the surface layer from the distribution. Nucleotides that emit gamma rays with energy available for exploration include bismuth (214 Bi), thallium (208 Tl), and potassium (40 K). These nuclides migrate as a gas or as dissolved in groundwater, and are concentrated in a single layer or a heated part. This increases the intensity of the gamma rays where cracks exposed to the surface extend to the subsurface.
Further, when the monolayer is clayed and the water content is large, the radioactivity may be lowered in the opposite direction. Using these phenomena, the gamma ray intensity is measured to confirm the geological structure of fault. That is, if the ground forms a geological rescue zone such as a crack zone and a fault zone due to the crustal change, it becomes a transport channel and accumulation zone of more radioactive materials than other areas, and a strong radioactive anomaly occurs here.
The NaI scintillation meter has been used for the exploration of radioactive minerals such as uranium deposits, but recently it has been used for the detection of faults and fractures for purposes such as groundwater and hot spring development, civil engineering construction and earthquake disaster prevention.
The problem of the NaI scintillation meter is to obtain the gamma ray intensity distribution of the surface of the earth, and it is not possible to explore the underground surface. The intensity of gamma rays emitted from radioactive isotopes is attenuated by interaction with substances or distance effects.
Most of the gamma rays detected near the surface are due to the ground within 10 cm below the surface. Thus, the measured gamma-ray intensity strongly reflects the influence of strata covering the surface. When the exposed part of the rock and the alluvial layer are thick, their strength is different and they are influenced by the material of the embankment and the artificial structure.
Consideration should be given to surface conditions such as surface lipids and artificial structures, and a careful examination of the results is necessary. For the purpose of identifying faults, many cases are carried out with the cracks exposed to the surface. In general, the intensity of the gamma rays is high. When the cracks are exposed to the surface, the intensity is low.
Total gamma ray dose, potassium, bismuth, thallium The gamma ray intensity of each photoelectric maximum point is obtained, and it is summarized by a sideline, and it is indicated by a line graph or the like.
2) Geiger counter (Geiger counter)
When the radiation generated by the collapse of radioactive elements into a stable isotope enters the discharge tube, the gas ionizes and instantaneously discharges and current flows. The current is amplified and the number of the incoming signal is counted, and the radioactive element content is confirmed and utilized for the exploration. However, this method is relatively inaccurate because gas is ionized to detect radioactive elements.
Geiger counters are relatively inexpensive and gamma rays are very sensitive to high energy components, but they are not an effective exploration method because they can not output pulses proportional to the detected gamma ray energy.
The Geiger counter method is also known as an ionospheric chamber measurement method.
3) Alpha Cup (Alpha Probe Detector)
Charge charge detectors cellulose nitrate and CR-39 (GE) and LR-115 (Kodak KODAK, France) plastic contrast detectors are used. To detect the alpha-decaying radon content, a radon cup with a plastic non-detectable detector is used. The alpha-track of alpha decay in the plastic non-detectors is quantitatively analyzed after diluted hydrochloric acid treatment and compared with standard samples under a microscope.
The principle of detection of the alpha-polarity detector is to detect radon and radon at 3.82 days on solid film surfaces such as polyallyl diglycol carbonate (CR-39), cellulose nitrate (LR-115) and polycarbonate (PC: Makrofol, polycarbonate) When the alpha particles of the collapsed offspring are incident, microscopic damage to the structure of the material results in flight, and the number of detections is counted to determine the concentration of radon.
The resist produced on the film is chemically or electrochemically etched with a solution of sodium hydroxide (NaOH) to enlarge the size of the damaged trace, and then a microscope, an image processor or an automated optical scanning system Count the maneuver.
The Alpha Cup (Alpha-Non-Detector) measures the alpha from the uranium decay process. The problem is that the alpha cup is buried in the field and it is recovered after 3 weeks to count the track of the alpha track to determine the radon content. The problem with alpha cups is that short-term measurements are difficult if the concentration of radon is not high. In addition, the static charge on the film surface affects the radon daunion attachment to the film surface. Ultraviolet and moisture changes the film quality over time, and some detectors also produce tracks by thoron.
The passive radon concentration detecting apparatus of the present invention can be selected from NaI scintillation meters, gauge counters, and alpha cups, and preferably the NaI scintillation meter is used as a NaI radon detector.

4 is a flowchart illustrating an operation method of a passive radon concentration detecting apparatus according to an embodiment of the present invention.
Hereinafter, a method of operating a passive radon concentration detecting apparatus including a radon measuring unit, a radon detecting control unit, an environment detecting sensor unit, a detection error sensor unit, a Bluetooth communication unit, a Wi-Fi communication unit, and an Ethernet communication unit will be described in detail with reference to all the accompanying drawings. The radon detection application, the operation data, the operation program, the reference value, the control command, and the like are downloaded from the operator or the user via the Bluetooth communication unit, the Wi-Fi communication unit, and the Ethernet communication unit operated by the radon detection control unit and stored in the allocated area (S110) and determines whether a control command to start the radon concentration detection is input (S120).
The radon detection controller sets one of the first periodic time value and the second periodic time value as the reference period value (S130) and determines whether the radon detection app is operated (S140).
The first cycle time value is designated and set to a value corresponding to twice the second cycle time value and the first cycle time value is designated and set to any one value selected from the range of 1 minute to 5 minutes, It is relatively preferable to designate and set the time of the time period as the cycle time value, and it is quite natural that it can be added or subtracted as needed.
The reason why the first cycle time value is set to a value corresponding to twice the second cycle time value is to make the measurement time irregular so that the average value can be measured.
The radon detection control unit detects the radon concentration value at a predetermined detection cycle time (S150), and controls the environment detection sensor unit to be in an activated state to detect ambient temperature, humidity, ventilation, and air pressure, And the final compensated value is output as the compensated radon concentration detection value (S160).
The exponentiation operation is already well-known as an arithmetic operation that takes twice the value of the previous step for each step, such as a multiple of 1 for stage 1, a multiple of 2 for stage 1, Therefore, a more detailed description will be omitted.
The radon detection control section explains that the operation is an absolute value in the geometric series calculation, and the applicable plus and minus are finally applied.
In one embodiment, the radon detection control unit may be configured such that the radon detection control unit determines that the specified unit specification value of the temperature value is +2, the specified unit specification value of the humidity value is-2, If the specified unit specification value of the air pressure value is a value of - 2, the compensated radon concentration detection value obtained in the final compensation operation is the same value as the radon concentration value detected in the radon measurement unit. In addition, even when the sum of the unit specification values is the absolute value 1, the measured value and the calculated value may be the same.
The radon detection control unit activates the detection error sensor unit at every detection cycle time to detect illuminance, position movement, and accumulated time values, stores the analyzed values in an allocated area, and analyzes the detected difference values. And transmits the error message to the worker, the manager or the operator who is the specified partner in real time (S170).
If it is determined that the radon detection is to be continued (S180), the radon detection control unit switches one of the currently set values among the first and second periodic time values to another value that is not currently set (S190) , And returns to the second step (S140).
FIG. 5 is a photograph of an external appearance of a lardon trapping part constituting a radon detecting part of a passive radon concentration detecting device according to an embodiment of the present invention.
In the method of collecting lardon gas, activated carbon is used for filling lardon gas, activated carbon is filled in the lid, sealed and commercialized, and after the customer opens the lid according to the instructions, the lid can be continuously collected for two days by one embodiment.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
