Description

COLLECTING APPARATUS FOR REMOVING RADON IN SOIL UNDER BUILDING}

The present invention relates to a collecting device for removing radon, and more particularly, to collect radon in the form of gas generated in the soil in the basement of a previously constructed building to remove and remove it into the atmosphere to prevent radon from entering the room. It relates to a collecting device for removing radon in underground soil.

In general, radon (Rn) is a gaseous radioactive material produced by the radioactive decay process of uranium and thorium contained in the earth's crust.

Radon's isotopes ²¹⁹ Rn, ²²⁰ Rn, and ²²² Rn are produced as intermediates in the natural radioactive decay chains of uranium and thorium, where ²¹⁹ Rn is at ²³⁵ U of natural decay (actinium series), ²²⁰ Rn is ²³² Th Thorium), and ²²² Rn is ²²³ Ra (t1 / 2 = 11 days), ²²⁴ Ra (t1 / 2 = 3.66 days), ²²⁶ Ra (t1 / 2 = 1600) at ²³⁸ U spontaneous decay (uranium series), respectively. Is produced by α decay.

Radon is found in uranium ores, phosphate, igneous and metamorphic rocks, limestone, soil and petroleum, trace amounts are contained in the atmosphere and the earth's crust. Therefore, radon can accumulate at higher concentrations than in the outside atmosphere in rooms or basements in some poorly ventilated buildings.

In addition, radon is a colorless, odorless and tasteless inert gas, and because it is mobile and heavier than air, radon remaining in surrounding construction materials, soil, and groundwater is concentrated in the basement through cracks of soil, cement, and ground. It may be introduced into the room, and even if the concentration of radon in the indoor atmosphere is low, it may be absorbed by the human body and damage the lung by generating radiation.

The National Cancer Center (NCI) defines radon as a first-class carcinogen along with asbestos, and the US Environmental Protection Agency (EPA) defines radon as the next most dangerous cause of lung cancer after smoking. Recent studies have shown that radon has a higher average radiation exposure for the general population than for medical activities such as total natural radiation or X-rays.

In the related art, Patent Document 1 discloses a passive sub-slab depressurization (PSD) radon discharge device and an active sub-slab depressurization (ASD) radon discharge device.

Figure 2a is a view of the prior art PSD radon discharging device, the exhaust pipe 50 is installed in the lower portion of the slab 15 of the building 10 to the outside of the radon accumulated in the soil 20 under the building 10 To be discharged. The slab (30) is placed on top of the soil (20) on which the building (10) is installed, and after installing the sealing polyethylene sheet (40) to block the inflow of radon's interior space (14), the slab ( 15), and the exhaust pipe 50 for ventilation between the gravel layer 30 and the polyethylene sheet 40 passes through the wall 11, roof 12 or ceiling 13 of the building 10 to the outside. By being installed in the furnace, radon flowing from the soil moves in the gravel layer 30 having a large flow space and is discharged to the outside through the exhaust pipe 50.

However, the above-described PSD radon discharge device discharges radon using the temperature difference inside the exhaust pipe, the air pressure difference between the interior space and the lower part of the building, so that the radon removal efficiency is low, which is not efficient.

FIG. 2B is a view illustrating an ASD radon discharge device, in which an exhaust pipe 50 is installed below the slab 15 of the building 10 and an exhaust fan 60 is installed in the exhaust pipe 50. The radon accumulated in the soil 20 is forcibly exhausted to the outside. The exhaust fan 60 allows a low pressure space to be formed between the slab 15 and the soil 20 through forced exhaust so that radon from the soil is moved to the low pressure space of the building floor through the gravel layer 30. Radon gas is exhausted to the outside through the exhaust pipe 50 connected to the roof 12 of the building.

However, the above-mentioned ASD radon discharge device is limited to the application of technology because it can be installed only in a newly constructed building, and it is difficult to secure a space for inhaling radon because it is buried in the soil. When the vibration occurs due to the operation of the suction fan or there is a problem that can be broken by the radon leak or soil collapse. In addition, foreign matters such as gravel or soil may be introduced together with radon, which may cause a failure of an exhaust fan or the like, and may be difficult to combine and separate, and may not be moved and reinstalled.
