Q2: What does the occasional green light flashing mean?
A: When the device detects alpha decay of radon, the green indicator light
will flash once.
Q3: What does the occasional "beep" of the buzzer mean?
A: If the particle sound function is turned on, when the device detects alpha
decay of radon, the buzzer will sound once.
Q4: What is the total count?
A: It is the count value of detecting alpha decay of radon. The radon
concentration value is calculated by integrating this count value.
Q5: How to accurately measure when the environmental humidity is higher
than 90%?
A: The current high detection environment humidity will affect the detection
result. It is recommended to control the relative environmental humidity
within 90%, or place granular desiccant at the bottom or on both sides of
the air inlet of the instrument (note not to use powder desiccant).
Q6: What does the red light flashing mean?
A: When the radon concentration exceeds the alarm limit, the red light and
buzzer will simultaneously trigger an alarm.
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.
