10.What is radon?
Radon is a dangerous radioactive gas. It is colorless, odorless, and
tasteless, and cannot be detected by human senses alone. Its density is
eight times that of air. Basements, schools, and houses with underground
facilities are prone accumulate high concentrations of radon, which is very
dangerous! The half-life of radon is 3.82 days, but it is always present in
our surrounding environment. Moreover, the period with the highest radon
concentration is at dawn when most people are sleeping.
Hazards: When inhaled into the body, the alpha particles emitted during
radon decay can cause radiation damage to the human respiratory system
and lead to lung cancer. It is especially fatal to infants and pregnant women.
According to the average radon level in a country, radon is estimated to
cause 3% to 14% of all lung cancers.
Sources: Radon mainly exists in the soil, and natural building materials
are the most important source of indoor radon.
Commonly used control measures: The simplest and most effective way
to reduce indoor radon concentration is to enhance indoor ventilation.
When the radon concentration exceeds 4 pCi/L (148 Bq/m³), ventilate for at
least 10 minutes or more.
