WHY WORRY ABOUT RADON?
Radon gas is the number 1 cause of lung cancer among non-smokers and kills 6
times more people than house fires and carbon monoxide combined. The US
Environmental Protection Agency recommends radon levels remain below 4 pCi/L.

GETTING STARTED
- Pull battery tab
- Allow for initial calibration (first indication in less than 24 hours)
- Place in the lowest liveable area of your home (basement or 1st floor)
- Leave undisturbed for at least 2 months to get a good indication of your radon levels*
- Radon levels fluctuate constantly, it is important to continuously monitor
DEVICE SPECIFICATIONS
A. “SHORT TERM AVERAGE” shows the short-term average measurement for the past
24 hours (updated hourly) or 7 days
(updated daily). (Switches between the two every 6 seconds)
B. Low battery level indicator. Change batteries as soon as the icon appears.
C. “LONG TERM AVERAGE” shows the long-term average measurement for up to one
year (updated once per day).
D. The measurement indicator will blink when the instrument is active.
E. USB input for manufacturer use only (if present).
F. “RESET” button, which can be used to start a new measurement period. Note:
this removes all stored data from the previous
measurement.
G. “MODE” button for use when generating a report at
airthings.com/report. Press once for the total
number of days measured, and twice for a code to receive your radon report.
H. Battery compartment for 3 AAA batteries (included).
EVERYDAY USE
What do my levels mean?
Radon is measured in picocuries/Liter (pCi/L).
Higher than 4 pCi/L
POOR: Keep measuring. If levels are maintained
for more than 1 month, contact a radon mitigation professional.
Between 2 and 4 pCi/L FAIR: Keep measuring, if levels are maintained for more
than 3 months, contact radon mitigation professional.
Less than 2 pCi/L
GOOD: No action needed, continue monitoring.
PLACEMENT
Place the device in living areas on lower levels, such as a basement or living
room. The device should not be exposed to direct sunlight or moisture. It
should be placed at least 1.5ft/50cm above the ground and at least 5ft/150cm
from the nearest door, window, or air vent. Do not move the device during
measurement. The screen should be facing upwards. The device can be laid flat
on a surface with the screen facing up (recommended) or mounted on a wall.
High humidity levels (over 85%) can cause permanent damage to the device,
erratic readings, and/or error codes.
ACCURACY
Results are more accurate over a longer measurement period. We recommend
measuring for at least 2 months for a good indication of your long-term
exposure.
LONG TERM VS. SHORT TERM AVERAGES
After a full 7-days of measuring your detector will start to switch from a
24-hour measurement to a 7-day average every 6 seconds. The long-term average
is intended to identify potential health hazards, while the short-term average
should be used to assess the effects of radon reduction efforts, such as
increased ventilation, sealing cracks, etc.
