Because radon gas is odorless and tasteless, radon testing is the only way to ascertain whether the radon levels within the Allentown PA dwelling are hazardous. Testing of radon levels is usually the first step taken before mitigation can be done. Radon testing helps to determine both the long-term and short-term risk of exposure within the building. According to the World Health Organization, radon levels of 2.7 pCi/l in the air is considered to be a threat. Short-term radon testing is the fastest way to detect unhealthy radon levels. However, when “marginal” short-term levels (2 pCi/l to 5 pCi/l) are identified, a retest is recommended to ensure that the first test was an accurate assessment of indoor radon exposure within the dwelling. This is because radon levels tend to fluctuate due to changes in pressure and other weather conditions.
When testing for the presence of radon, devices are deployed in the building. Some radon testing devices display radon levels “real time” on a digital display. In other cases, the devices must be sent to the laboratory for analysis. However, if radon gas is being tested in the water supply, then the analysis must be done in the laboratory so the radioactive decay products can be counted within the water sample. In Allentown Pennsylvania, it is fairly uncommon to find waterborne radon levels high enough to warrant mitigation. However, it would be advisable to test the water supply just to be certain, especially if the water is supplied from an underground well.
