Description

Radon emission system for reducing radon emitted in apartment houses {RADON EMISSIONS SYSTEM FOR REDUCTION RADON EMITTED FROM APARTMENT HOUSES}

The present invention relates to a radon emission system for reducing radon emitted in an apartment building.

In general, Radon (Rn) is a kind of natural radioactive gas that causes alpha decay with a half-life of 3.8 days. Although it is introduced into the room through the building, it is also generated from cement and soil used in the construction of buildings, and uranium decay products included in other interior and exterior materials, and is introduced into the room.

When radon enters the lungs through the respiratory system, it kills cells in the lungs and becomes the main culprit of cancer. It is specified as a major cause of radon, and it is recommended to manage the radon concentration in indoor air. Radon exists in outdoor air or groundwater, but exposure through indoor air accounts for about 95% of the exposure.

In other words, since radon is the heaviest gas on earth, once it enters a room, it does not escape and accumulates. Through human breathing, radon enters the lungs and collapses, releasing alpha radiation. As an atomic nucleus (He ²⁺ ), it has weaker penetrating power than beta or gamma rays, but has a relatively large mass and causes destruction of lung cells.

On the other hand, radon gas, which is the main cause of radiation exposure to the general public, continuously moves to the ground through soil or gravel surrounding buildings, and penetrates indoors through the spaces of buildings or pores of concrete. Similarly, radon penetrating from the surrounding soil is known to be the main cause of indoor radon, and building materials such as concrete, gypsum board, pebbles, and bricks are also sources of indoor radon contamination.

In addition, since radon is well soluble in water, it is introduced into the room through the movement of groundwater, and the movement through water penetrates the room due to capillary action or water pressure through the pores of concrete, and the indoor temperature is high or the indoor pressure The lower it is, the more radon gas is introduced into the room.

In addition, various building materials such as cement and concrete have potential risks of emitting various harmful substances such as volatile organic substances, inorganic gases, and heavy metals on their own as well as radon gas.

That is, since concrete or gypsum board, etc. used in the construction of a building contains radium, although in a small amount, after constructing the building, the radium contained in the concrete or gypsum board undergoes nuclear fission to generate radon gas. Radon gas is often accumulated indoors without being discharged outdoors, adversely affecting the health of people living in buildings.

Therefore, recently, as shown in a number of prior documents including Korean Patent Registration No. 10-0977707, radon blocking materials are applied to concrete walls, or radon blocking agents are mixed with concrete to suppress the release of radon gas. Methods for reducing damage caused by gas are being developed, but these methods are insufficient to effectively prevent damage caused by radon gas generated from concrete walls or gypsum boards.

On the other hand, in order to reduce radon gas entering the room, periodic ventilation by residents is mainly required, but in the case of cold winter or nighttime, since ventilation is not properly performed, residents are exposed to radon gas and suffer serious damage. .

In particular, in the case of multi-household apartments, etc., systematic management of radon gas is not carried out, so the health of apartment residents is concerned. In order to solve this problem, radon is measured to keep radon gas below a certain level. Thus, devices for reducing radon gas are being developed.

That is, the prior art radon gas reduction system installs a radon gas detection sensor for detecting radon gas in each room, and then controls the ventilation system of each room according to the detected concentration of radon gas so that the radon gas concentration in each room is regulated. It is managed to keep it below the set level.

On the other hand, in the case of domestic apartments or apartment houses being built today, the sealing rate is very high at about 90%, and it is legally obliged to install compulsory ventilation equipment. This ventilation facility is equipped with a static pressure ventilation fan to minimize the influence of the number of floors and the external environment, and is designed to focus only on indoor and outdoor air ventilation. As a result, in the process of installing the product, there are many cases in which negative pressure in the room is formed in some products due to problems with the installation of internal piping.

Due to this problem, households that emit more radon indoors are often found. The highest concentration of radon in the home is between 10:00 p.m. and 5:00 a.m. At this time, the peak of radon in homes appears. In this time zone, indoor ventilation should be continuously performed, but there is a problem in that the ventilation is not actively ventilated due to air conditioning and heating problems, so that the room is exposed to radon as it is. Therefore, there is a need for a new method capable of solving these problems.

In addition, the radon measuring devices 900-1 to 900-N for each room are installed for each room of each household, and perform a function of measuring the radon concentration in each room provided for each household.

It is preferable that the radon measuring devices (900-1 to 900-N) for each room include, for example, a pulsed ionization chamber type radon measuring sensor, but are not limited thereto, and, for example, to detect alpha particles. As a device for this, a surface barrier type, a high purity semiconductor detector (Pure Ge), a scintillation (scintillation) detector, a solid state junction counter, or the like may be applied.

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

When alpha decay occurs inside the ionization chamber and alpha particles are emitted, the alpha particles disappear due to collision with air, but since ion charges are generated, the alpha particles can be detected by absorbing them through the central probe and amplifying the signal. Since the sensor itself consists of a metal cylinder and a probe, it is very inexpensive, has good durability, and is independent of light, so it has the advantage of improving air permeability.

Looking at the surface barrier type detector, a depletion layer such as a P-N junction is formed on the surface of a semiconductor due to a surface level or an oxide film, and the vicinity of the surface becomes an obstacle to charge transfer. As a practical one, gold is deposited on the surface of N-type Si at about 100 μm/cm 2 , and radiation is incident on the back side using this as one electrode. Here, the thickness of the depletion layer varies from about 50 to 500 μm, and since the energy loss on the surface is small, it is mainly used for detecting charged particles generated by alpha radiation and has good energy resolution.

The high-purity semiconductor detector is also generally referred to as a pure Ge detector. It is a high-purity Ge crystal with a very small impurity concentration or defects. It has a very high electrical resistance at a low temperature and can apply a high bias voltage. It differs from Ge(Li) in that it can be stored at room temperature, cooled with liquid nitrogen only for measurement, so it is easy to maintain, and its energy resolution is comparable to Ge(Li), so it is being put into practical use.

Looking at the scintillation detector, the phenomenon of light emission when charged particles collide with a substance has been known for a long time, but the emission by alpha radiation of zinc emulsified (ZnS) or NaI coating is particularly strong, and can be detected and counted with a magnifying glass in a dark room.

Such light emission is called scintillation, and a material exhibiting this phenomenon is called a scintillator. A combination of a photomultiplier tube with a scintillator is called a scintillation detector, but a method using a pulse output for counting is called a scintillation counter.

On the other hand, the direct current reading method is mainly used for dose measurement and is called a scintillation dosimeter because it uses a scintillator. Any solid, liquid, or gas is used for the scintillator, and if a liquid is used, a liquid scintillation counter device say

The solid junction counter is a solid reverse-bias P-N junction semiconductor, and can be manufactured as a compact and portable counter configured to collect ion charges from alpha particles passing through a depletion layer.
