Radon map of the United States ASTM E-2121 is a United States standard for reducing air-born radon in homes as far as practicable below the action level of 4 picocuries per liter (p, Ci/L) (148 Bq/ m3). Some states advise achieving 2. 0 p, Ci/L or less. Radon test sets are commercially available and can be used by house owners, occupants and in limited cases by proprietors, except when a residential or commercial property is for sale. Commercially offered You Can Try This Source includes a passive collector that the user places in the least expensive livable floor of the home for 2 to 7 days.

Open land test sets can test radon emissions from the land before building and construction starts, but are not recommended by the EPA due to the fact that they do not properly forecast the last indoor radon level. The EPA and the National Environmental Health Association have determined 15 kinds of radon test devices. A Lucas cell is one kind of device. Retesting is particularly recommended in numerous scenarios. Measurements between 4 and 10 p, Ci/L (148 and 370 Bq/m3) call for a follow-up short-term or long-lasting radon test prior to mitigation. Measurements over 10 p, Ci/L (370 Bq/m3) warrant just another short-term test (not a long term test) so that abatement procedures are not unduly postponed.
Radon Remediation Cost, Solutions and Methods - Radon-Rid, LLCThe accuracy of the domestic radon test depends upon the absence of ventilation in your house when the sample is being obtained.

Additionally, there may be children or immature teenagers or young people in the house who will open a window for ventilation regardless of guidelines not to do so, particularly in uncomfortably heat.
