2.What does the occasional green light flashing mean?
Answer: When the device detects alpha decay of radon gas, the green
indicator light will flash once.
3.What does the occasional "beep" of the buzzer mean?
Answer: If the particle sound function is turned on, when the device
detects alpha decay of radon gas, the buzzer will sound once.
4.What is the total count?
Answer: It is the count value of detecting alpha decay of radon gas. The
radon concentration value is calculated by integrating this count value.
5.How to accurately measure when the environmental humidity is
higher than 90%?
Answer: The current high detection environment humidity will affect the
detection result. It is recommended to control the relative environmen-
tal 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).
6.What does the red light flashing mean?
Answer: 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 under-
ground facilities are prone to accumulate high concentrations of radon
gas, 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.
