Description

Soil radon measurement device using soil environment analysis {SOIL RADON MEASUREMENT APPARATUS USING SOIL ENVIRONMENTAL ANALYSIS}

The present invention relates to a soil radon measurement device using soil environment analysis.

Sick buildings where pathological symptoms such as chronic colds, cough, phlegm, nasal irritation, breathing difficulties, respiratory diseases, headaches, eye irritation, etc. occur due to worsening indoor air quality caused by recent urbanization, density of buildings, and complex housing patterns. Social interest in the syndrome is emerging.

The main causes of sick building syndrome are sick building syndrome and soil gas flowing in from the soil layer. Sick house syndrome is caused by carcinogens such as benzene, toluene, chloroform, acetone, styrene, and formaldehyde, which are harmful substances emitted from building materials and wallpaper used when constructing a new building, or radon, asbestos, carbon monoxide, and It is caused by pollutants such as carbon dioxide, nitrogen oxides, ozone, fine dust, and floating bacteria.

Radon, which is included in soil gas and the causative agent of sick building syndrome, is a naturally occurring colorless, odorless, and tasteless water-soluble radioactive gas with isotopes of atomic weights of 219, 220, and 222, respectively, U-235, Th-232, and As a radioactive decay product of U-222, it is a group 0 gas and is not chemically reactive. However, when radon atoms in the air are inhaled through human breathing, some remain in the lungs and separate into highly reactive metal atoms such as polonium, bismuth, and lead. do. During this process, harmful radiation is emitted into the body's sensitive lung tissue, causing lung cancer.

Most of the radon, which is very harmful to health, originates from the soil or rocks of the building ground. Radon or other polluting gases that pass through the soil layer continue to accumulate in the lower part of the building.

Normally, the atmospheric pressure inside a building is lower than the pressure in the soil below the building. Due to the high pressure in the soil below the building, harmful gases such as radon are introduced into the room where the pressure is low through the floor or walls of the building.

Most radon gas enters through cracks in walls or other connecting passages between indoors and outdoors. Once radon enters, it cannot escape easily and continues to accumulate indoors, threatening the health of residents.

Accordingly, in recent years, methods for predicting the amount of radon gas flowing into a building by measuring the concentration of radon gas emitted in the soil have been continuously researched.

Hereinafter, we will look in detail at the components of the soil radon measurement device using soil environment analysis according to an embodiment of the present invention.

The probe 100 is inserted into the soil at a certain length (preferably about 70 to 80 cm), and a space 110 is formed therein to collect air containing radon gas emitted from the soil. there is.

The moving pipe 150 is connected in communication with the space 110 of the probe rod 100, and performs the function of moving air containing radon gas collected in the space 110 of the probe rod 100 to the outside. .

The air flow meter 200 is mounted on the moving pipe 150, is connected to the control module 450, and performs the function of measuring the flow rate of air moving within the moving pipe 150 under the control of the control module 450. .

The air pump 250 is connected to the moving pipe 150 and is connected to the control module 450 to pump the radon gas collected in the space 110 of the probe 100 under the control of the control module 450. It performs the function of forcibly sucking air at a certain flow rate.

The radon meter 300 is connected to the moving pipe 150, and is connected to the control module 450, so that air containing radon gas is introduced at a constant flow rate through the air pump 250 under the control of the control module 450. It performs the function of measuring the radon concentration in the air.

This radon meter 300 preferably includes, for example, a Pulsed Ionization Chamber type radon measurement sensor, but is not limited thereto, and is, for example, a surface barrier type device for detecting alpha particles. Type), high purity semiconductor detector (Pure Ge), scintillation detector, solid state junction counter, etc. may be applied.

That is, the ionization chamber type radon measurement sensor has a structure in which a probe-shaped electrode is installed in the center of a metal cylindrical box, and a bias voltage is applied between the metal cylinder and the internal probe to form an electric field.

When alpha decay occurs inside the ionization chamber and alpha particles are released, the alpha particles are destroyed by collision with air, but ion charges are generated, so the alpha particles can be detected by absorbing them through the central probe and amplifying the signal. The sensor itself is composed of a metal cylinder and a probe, so it is very inexpensive, durable, and independent of light, so it has the advantage of improving breathability.

Looking at the surface barrier type detector, a depletion layer such as a P-N junction is formed on the surface of the semiconductor due to the surface level or oxide film, so that the vicinity of the surface becomes an obstacle to charge movement. In practical terms, gold is deposited on the surface of N-type Si at a thickness of about 100㎛/cm2, this is used as one electrode, and radiation is incident on the back side. Here, the thickness of the depletion layer varies from about 50 to 500㎛, and because the energy loss at the surface is small, it is mainly used to detect charged particles generated by alpha radiation and has good energy resolution.

The high-purity semiconductor detector is also commonly called a Pure Ge detector. It is a high-purity Ge crystal with very low impurity concentration or defects, has very high electrical resistance at low temperatures, and can apply a high bias voltage. The difference from Ge(Li) is that it can be stored at room temperature and only needs to be cooled with liquid nitrogen for measurement, making it easy to maintain, and its energy resolution is comparable to that of Ge(Li), so it is being put into practical use.

Looking at the scintillation detector, the phenomenon of a charged particle emitting light when it hits a material has been known for a long time, but the luminescence caused by alpha radiation from zinc emulsified (ZnS) or NaI coating films is particularly strong and can be detected and counted with a magnifying glass in a dark room.

This kind of light emission is called scintillation, and the material that exhibits this phenomenon is called a scintillator. And, a scintillator combined with a photomultiplier tube is called a scintillation detector, but the method used for counting, especially as a pulse output, is called a scintillation counter.

On the other hand, the method of reading the output in direct current is mainly used for dosimetry. Since it uses a scintillator, it is called a scintillation dosimeter. Any of solid, liquid, or gas is used for the scintillator. If liquid is used, a liquid scintillation counting device is used. It is said that

The solid junction counter is a solid reverse bias P-N junction semiconductor that collects ion charges from alpha particles passing through the depletion layer and can be manufactured in a small and portable form.

The humidity measurement module 350 is mounted on the space 110 and/or the moving pipe 150 of the probe 100, and is connected to the control module 450 so that it is stored in the soil under the control of the control module 450. It performs the function of measuring the humidity in the air containing emitted radon gas.

This humidity measurement module 350 is implemented as a humidity measurement sensor for measuring humidity in the air. The humidity measurement sensor usually measures humidity using changes in the electrical properties of a moisture-sensitive material due to moisture.

These humidity measurement sensors can be broadly divided into resistance-type humidity sensors and capacitance-type humidity sensors, and are widely applied to optimize not only home appliances and mobile devices, but also automobiles, medical devices, air purification systems, and automatic cooling and heating systems. It is becoming.

The resistance-type humidity sensor measures humidity using changes in resistance that change due to humidity. This resistance-type humidity sensor was widely used because it was relatively price competitive compared to the capacitive humidity sensor.

However, recently, as capacitive humidity sensors have become possible to be manufactured in the form of one chip on a semiconductor substrate, their use is increasing as they can secure a price competitive advantage over the resistance-type humidity sensors. In particular, capacitive humidity sensors have the advantage of having superior reliability compared to resistance-type humidity sensors, while having linear sensor characteristics and less influence of temperature.

This type of capacitive humidity sensor is a sensor that uses the principle that capacitance changes depending on the molecular weight of water adsorbed on the moisture-sensitive film. It uses moisture-sensitive materials such as polyimide or ceramic, whose dielectric constant changes when moisture is absorbed. It operates in the form of a capacitor made of dielectric. In other words, the principle is that there is a moisture-sensitive layer that senses humidity, and as moisture flows through this moisture-sensitive layer, the dielectric constant changes and the capacitance changes accordingly.

The pressure measurement module 400 is mounted on the moving pipe 150 and/or the air pump 250, and is connected to the control module 450 to suck air through the air pump 250 under the control of the control module 450. It performs the function of measuring the intake pressure of air.

The control module 450 performs overall control of the soil radon measurement device using soil environment analysis according to an embodiment of the present invention. In particular, the probe rod 100 is based on the air flow rate value measured from the air flow meter 200. ) performs the function of controlling the operation of the air flow meter 200 and the air pump 250 so that the air containing radon gas collected in the space 110 flows into the radon meter 300 by a preset inflow amount.

In addition, the control module 450 receives in real time the soil humidity and suction pressure values measured from the humidity measurement module 350 and the pressure measurement module 400, respectively, and based on this, the soil according to the preset humidity and pressure is provided. It performs the function of calculating the air permeability of the soil according to the measured soil humidity value and suction pressure value using the air permeability information data.

Here, the soil air permeability information data according to the preset humidity and suction pressure is the soil air permeability information according to humidity and suction pressure, as shown in the permeability graph and humidity correction graph shown in FIG. 4, in the database (DB). It is preferable that the data is stored in the data storage module 550.

For example, if the radon concentration emitted from the soil is 10,000 becquerels, the suction pressure is 15 pascals, and the soil humidity is 70% because it has just rained, the soil air permeability is indicated as 10E-14. If there is no standard for soil humidity, the soil air permeability should be expressed as 10E-14 according to the currently measured value. However, measurements cannot be made every time the soil bottom dries. Therefore, it is necessary to obtain the soil air permeability at standard humidity. When humidity is high, the suction pressure will increase and the air permeability of the soil will be correspondingly low. However, if the humidity deviation is corrected, there is a different interpretation.

On the other hand, if the soil humidity standard is 50%, the humidity deviation is 20%, and since the currently measured humidity is 20% higher than the standard humidity, the currently measured value moves to the upper left graph according to the deviation of the humidity correction graph. do.

Assuming 50% humidity, the suction pressure decreases and the air permeability of the soil increases, so the measurement point in the upper left corner changes according to the humidity correction graph, and the final correction value will be obtained.

In addition, the control module 450 calculates the air permeability of the soil and the radon meter 300 based on the soil humidity and suction pressure values measured from the humidity measurement module 350 and the pressure measurement module 400, respectively.
