Decoration, what are you most afraid of?
It's not that the cost is high, it's not that the real scene is ugly, but the toxic and harmful gases produced in the decoration.
Take formaldehyde as an example, you can't see it, but as long as you are in an environment where formaldehyde exceeds the standard, your eyes will be irritated, your throat will be irritated, and your breathing will be uncomfortable.
#01
It is more harmful than formaldehyde
The harm of formaldehyde has made many people afraid of decoration, but what you don't know is that there is also a substance produced in decoration, which has a certain degree of radiation and is even more harmful than formaldehyde.
It is radon, which, like formaldehyde, is also present indoors.
Radon is colorless, odorless and radioactive. It is the product of the decay of radium and thorium. It is the only natural radioactive noble gas in nature. Under normal temperature conditions, the radioactive aerosol formed by radon is suspended in the air and will continue to accumulate in the body with human breathing.
Usually, radon accounts for almost half of the natural background radiation dose we are exposed to.
The biggest hazard of radon is that it causes cancer.
It has been listed as the first among three types of carcinogens by the World Health Organization. According to relevant data: 15 cigarettes/day = 200 Baker/m radon concentration, the number of lung cancer cases caused by radon in my country has exceeded 50,000 every year, which is the second most carcinogenic method after cigarettes.

What are the sources of radon pollution?
To avoid the harm of radon, we must first figure out what is the source of radon pollution?
There are four main sources of radon pollution:
1. Geological structure
If the stratum contains radioactive substances such as uranium, radium, and radon, the substances will precipitate from the soil of the foundation, enter the soil through the bottom fault zone, and diffuse into the room.
2. Indoor and outdoor air
There is radon-containing gas outdoors, and radon is also released from the natural gas we use.
3. Building materials
Building materials such as sand, bricks, and cement contain radon.
Fourth, interior decoration materials
Gypsum, sanitary ware, ceramic tiles, etc. contain radon, among which granite, sandstone, and ceramic tiles have the highest content.

Avoid "radon" coup
Now that you have figured out the source of radon, let me show you how to avoid "radon"?
1. Construction site prevention and control
Before building the foundation, a professional organization should test and confirm the radon content. If the radon content is high, take corresponding measures to prevent radon from penetrating into the room.
2. Quality control of building materials
Developers should select materials in strict accordance with national standards and select reflective materials; users should also choose brands with guaranteed quality for decoration. If they are not sure, they can find professional institutions for testing.
3. Pay attention to indoor ventilation
The best way to keep indoor air clean is to ventilate, especially for houses that have just been delivered or renovated. If the family has the conditions, it can also be equipped with an air purifier with the function of purifying radon.
The hazards of radon and formaldehyde are similar, and they have a long incubation period, sometimes as long as more than ten years. Therefore, testing the radon content at any time to confirm whether the radon exceeds the standard or is about to exceed the standard is the best way to avoid "radon".
