" Evaluation of Guidelines for Exposures to Technologically Enhanced Normally Occurring Contaminated Products". A first test could not be a precise analysis of a house's average radon level. Therefore, a high outcome (over 4 pCi/L) warrants repeating the examination prior to embarking on a lot more pricey abatement jobs. Measurements between 4 and also 10 pCi/L warrant a long-term radon examination.
The National Radon Effectiveness Program (NRPP) gives a checklist of radon measurement professionals. The limitations preserved do not represent a known limit in the biological result, yet are established by a cost-efficiency evaluation.

- The danger models in their report, Health Impacts of Direct Exposure to Radon (the BEIR VI Report) (NAS/NRC 1999), consisted of factors to represent a decline in danger with time given that direct exposure.
- The National Academy of Sciences/National Research Council (NAS/NRC) was charged with examining the epidemiologic research studies.
