The average cost for an ASD radon mitigation system in Minnesota is $1500. [23] These costs are very dependent on the type of home and age of construction. [24]
Maps of average radon levels in houses are available, to assist in planning mitigation measures. [8] While high uranium in the soil/rock under a house does not always lead to a high radon level in air, a positive correlation between the uranium content of the soil and the radon level in air can be seen.
Radon concentration can differ widely from place to place. In the open air, it ranges from 1 to 100 Bq/m 3, even less (0.1 Bq/m 3) above the ocean. In caves or ventilated mines, or poorly ventilated houses, its concentration climbs to 20–2,000 Bq/m 3. [79] Radon concentration can be much higher in mining contexts.
To achieve these aims, WHO has formed a network of key partner agencies from some 40 Member States. This network is the basis for the WHO International Radon Project which was launched in 2005. Working groups will collect and analyse information on radon risk, radon policies, radon mitigation and prevention as well as risk communication.

In a report Tuesday, S&P Global Mobility reckoned that “importers are likely to pass most, if not all, of this (cost) increase to consumers.’’ TD Economics notes that average U.S. car prices ...
Radon mitigation methods include sealing concrete slab floors, basement foundations, water drainage systems, or by increasing ventilation. [96] They are usually cost effective and can greatly reduce or even eliminate the contamination and the associated health risks.
Installing a radon sump system in the basement; Sealing floors and walls (not a stand-alone solution); and; Installing a positive pressurization or positive supply ventilation system. The half-life for radon is 3.8 days, indicating that once the source is removed, the hazard will be greatly reduced within approximately one month (seven half-lives).
