Why should you test for Radon Gas?
Visit our information links to learn details of the Radon Gas hazard.
But the bottom line is:
The US Surgeon General identified Radon as the second leading cause of lung cancer.
The EPA estimated that Radon is responsible for over 25,000 cancer deaths annually,
10 times greater than from Carbon Monoxide.
Radon is a natural radioactive gas formed by uranium decaying in soil, rock, and
water. It is tasteless, odorless and invisible. Radon levels outdoors are typically
about 0.4pCi/L. Indoor levels above 4.0 pCi/L are considered a health threat over
the long term, that may result in lung cancer.
Buildings can have higher radon levels than the outdoors because of the vacuum effect
a building has on the ground on which it sits. Air pressure inside homes is usually
lower than air pressure in the soil around a home's foundation. So air is drawn
from the soil beneath a slab or through basement walls and floor via cracks and
mixes with air within the home. Over time, radon gas can accumulate to dangerous
levels within your home.
Radon levels fluctuate depending upon factors such as opening and closing windows
and doors to variations in outgassing of radon from the ground.
Radon gas levels in a home can vary on a daily basis between safe and hazardous,
cancer causing levels. Continuous radon testing with an electronic radon detector
allows you to note the variances.
- IMPORTANT: For Radon levels greater than 4.0 pCi/L take action. Contact a certified
Radon Mitigation specialist (often found under Radon Mitigation in the Yellow Pages)
or contact your State's Radon Expert for help with mitigation. State contacts
can be found via our Links Page.
|Newest Version: Safety Siren Radon Detector PRO 3 (SM-RAD-PRO3)|
Upgrades from the PRO 2 Model are:
The Pro Series 3 Radon Gas Detector is the only radon gas detector on the market
designed for use by the homeowner. This Series III Radon Detector was evaluated
by US EPA and meets performance criteria for the continuous radon protocol. Homeowner
can monitor the radon level in their home withn an easy to read digital display.
With this radon detector, the homeowner can monitor radon levels both with short-term
and long-term averages. The Radon Gas Monitor must be plugged in for 48 hours before
the first reading is displayed.
- EPA Evaluated.
- Radon reading to the nearest tenth, (no longer rounded up to a whole number)
- Alarm sounds if either long term or short term is above 4 pCi/L (alarm can still
- With these few exceptions, the basic circuitry of Pro 2 and Pro 3 is identical.
Radon is a colorless, tasteless, and odorless radioactive gas produced by the breakdown
of uranium in the soil. When allowed to accumulate to high levels, it can be hazardous
to long-term health.
The Surgeon General has warned that radon is the second leading cause of lung cancer
in the United States. Only cigarette smoking causes more lung cancer deaths.
Radon levels in a home can vary greatly over a one-month period going from safe
levels to dangerous levels and back to safe. Humidity, temperature, and season of
the year are major variables.
The EPA currently states that corrective action should be taken if radon levels
exceed 4 pCi/L (4 Pico-Curies per liter) on a long-term basis.
- Radon gas is impossible to detect without the use of sensitive test equipment.
- EVALUATED BY THE US EPA.
- Meets performance criteria for the continuous radon protocol by EPA.
Numeric LED display range of 0.0 to 999.9 shows the level of radon gas in pCi/L
on a short-term or long-term basis.
Short-term readings display the average radon levels over the past 7 days.
Long-term readings display the average radon levels since powered-up or last reset
with a maximum reading time of 5 years.
Audible alarm sounds if the long-term average reaches 4 pCi/L or greater.
Samples air continuously with the display updated every hour.
Conducts a failsafe self test every 24 hours with an error code displayed if there
is a failure.
- Menu button that controls 4 functions.
Allows the user to switch between the short-term and long-term display, indicated
by a green LED illuminated next to the S (short-term) or L (long-term).
Allows the user to conduct a manual test of the detector.
Allows the user to mute or reactivate the audible alarm if the detector is in an
- Allows the user to clear and reset the memory of the detector to begin new readings.
- Audible alarm sounds if:
The long term radon measurement reaches 4 pCi/L or greater.
The short term radon measurement stays above the 4 pCi/L for 30 consecutive days.
10 foot power cord allows the detector to be placed away from walls, windows and
- Full scale reading:
- Short term:
Average radon reading over past 7 days.
- Long term:
Average radon reading from time of last reset. Maximum sampling time of 5 years.
Detector automatically resets after 5 years of accumulated radon data.
- Audible Alarm:
85db at 10cm. Beeps every hour if short or long term radon levels are 4pCi/L or
greater. May be muted by user.
+/- 20% pCi/L
- NO Rounding:

- Sensor Voltage:
Each Pro 3 radon detector has a final accuracy test by testing against a high end
SUN nuclear radon unit.
- Note: The Pro 3 Radon Monitor requires a 48 hours sampling of air
before first accurate reading is displayed.
