==Radon Recommendations for Authorities==
<br/>
National authorities should:
*ICRP recommends setting a national reference level [[Fundamental Principles of Radiological Protection|'''as low as reasonably achievable''']] in the range of 100–300 [[Radon: Units of Measure|Bq/m<sup>3</sup>]].
*WHO guidance is basically the same: a national reference level of 100 [[Radon: Units of Measure|Bq/m<sup>3</sup>]] is recommended, and wherever this is not possible, the chosen level should not exceed 300 [[Radon: Units of Measure|Bq/m<sup>3</sup>]].
===Quotes From Publications===
Radon Protection Strategy:[[ICRP Publication 126|Publication 126]]<ref name="Pub126">[[ICRP Publication 126]] Radiological Protection against Radon Exposure Ann ICRP 43(3) 2014.</ref> paragraphs 41-45
''…Prevention of radon exposure is most relevant in new buildings. The implementation of preventive measures in new and renovated buildings provides a good partial solution… This also helps to develop awareness amongst professionals involved in the construction sector.''
''Remediation in existing buildings is also often appropriate in buildings with high radon concentrations. In such situations, there may be a primary source of radon ingress, and radon levels can often be reduced by a factor exceeding 10.
… the aim should be to reduce both the overall risk for the population and, for the sake of equity, the highest individual exposures to levels that are as low as reasonably achievable…''
''…The radon protection strategy should be properly scaled, with other health hazards and priorities identified in the country taken into account. Furthermore, comparison and integration between the radon protection strategy and other public health policies, such as non-smoking and indoor air quality policies, should be sought in order to avoid inconsistencies and achieve better effectiveness.''
''Considering the ubiquity of radon exposure, and the multiplicity and diversity of situations and decision makers, a straightforward, realistic, and integrated radon protection strategy, addressing most situations with the same approach, is appropriate. It must be supported and implemented on a long-term, potentially permanent basis, and involve all the relevant stakeholders. ''
National reference Level: [[ICRP Publication 126|Publication 126]]<ref name="Pub126">[[ICRP Publication 126]] Radiological Protection against Radon Exposure Ann ICRP 43(3) 2014.</ref> paragraphs 84, 76, and 86
''The first step is to characterise the exposure situation of individuals and the general population in the country, as well as other relevant economic and societal criteria, and the practicability of mitigating or preventing the exposure. … Many factors such as mean radon concentration and radon distribution, number of existing homes with high radon levels, etc. should be taken into consideration.''
''… The Commission strongly encourages … a national derived reference level that is as low as reasonably achievable in the range of 100–300 Bqm-3…''
''The value of the national derived reference level for radon exposure should be reviewed periodically to ensure that it remains appropriate. ''

Using the [[ICRPædia Guide to Dose Coefficients|dose coefficient]] for most circumstances of occupational exposure, breathing air with 50 [[Radon: Units of Measure|Bq/m<sup>3</sup>]] of radon (a typical worldwide value in buildings) for one year at work (2000 hours) gives an [[Absorbed, Equivalent, and Effective Dose|effective dose]] of 0.7 mSv. For working indoors doing substantial physical activity, or for exposures in tourist caves, the recommended [[ICRPædia Guide to Dose Coefficients|dose coefficient]] is higher, so breathing air with 50 [[Radon: Units of Measure|Bq/m<sup>3</sup>]] of radon for one year at work gives an [[Absorbed, Equivalent, and Effective Dose|effective dose]] of 1.4 mSv.
