Radon Test Singapore
iScientific offers Radon Test in Singapore. Radon is a naturally occurring radioactive gas formed from the radioactive decay of Uranium found in rock and soil. Radon gas rises freely through loose gravel, cracks and fissures underground, finding its way into homes and buildings. When air pressure inside a building is lower than air pressure outside a building, the building acts as a vacuum, pulling radon gas in through concrete pores, cracks and openings around piping and joints. Elevated radon levels and long term exposure in a home or building are considered health hazards.
Radon levels can vary by hour, seasons, weather conditions, climate, ventilation and with the use of heating and air conditioning systems. An initial short term test should be conducted to determine the need for further radon testing or mitigation.
Radon is odorless, colorless and tasteless, therefore radon collection devices are needed to detect potentially harmful concentration levels in a home. A continuous radon monitor can be used as a short term (48 hour) or long term (90 day) testing device.
What is an acceptable level of radon?
The U.S. EPA suggests indoor radon levels should be reduced below the action level of 4 pCi/L. A picoCurie (pCi) is a unit of radioactivity corresponding to an average of one decay every 27 seconds in a volume of one liter (L) of air.
If a short term radon test reveals a radon concentration below 4 pCi/L, it is likely that a year long test will also show the same result and no immediate action is necessary. If a short term test of 4 pCi/L or higher is confirmed, a second test should be conducted to confirm the first test, and if positive, mitigation steps should be taken to reduce the radon level in the home.
