Thus, uranium and radon will continue to occur for millions of years at about the same concentrations as they do now. [1] Radon is responsible for the majority of public exposure to ionizing radiation. It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location.
The four principal ways of reducing the amount of radon accumulating in a house are: [13] [174] Sub-slab depressurization (soil suction) by increasing under-floor ventilation; Improving the ventilation of the house and avoiding the transport of radon from the basement into living rooms; Installing a radon sump system in the basement;
Well water can be very rich in radon; the use of this water inside a house is another route allowing radon to enter the house. The radon can enter the air and then be a source of exposure to the humans, or the water can be consumed by humans which is a different exposure route. [10]
Remediation and insurance experts explain what to do if you see water pooling in your basement to stop it, prevent mold and mildew, and avoid future damage. So Your Basement Is Severely Flooded ...
Radon is measured in picocuries per liter of air (pCi/L) or becquerel per cubic meter (Bq m-3). Both are measurements of radioactivity. The World Health Organization (WHO) sets the ideal indoor radon levels at 100 Bq/m-3. [97] In the United States, it is recommend to fix homes with radon levels at or above 4 pCi/L.
High radon levels in a Minnesota (USA) basement with a passive under slab vent pipe system can be seen in the left half of the graph. After installation of a radon fan (ASD), a permanent reduction in radon levels to approximately 0.6 pCi/L can be seen in the right half of the graph. The most common approach is active soil depressurization (ASD).
Trying to buy a house right now might feel overwhelming, but waiting too long can present challenges as well. Review your finances in detail, and think about how much you’re able to pay upfront ...
The public needs to be aware of radon risks and the means to reduce and prevent these." [2] In 1996 [citation needed], WHO published a report containing several conclusions and recommendations covering the scientific understanding of radon risk and the need for countries to take action in the areas of risk management and risk communication.
