A 2018 estimate indicates that there were 226,057 radon-attributable lung cancer deaths in 66 countries that had representative radon surveys. This is a shocking figure, and as it comes from only 66 countries it underestimates the worldwide death toll. Any research that enables countries to conduct representative radon surveys and to understand better the risk to citizens from radon is surely welcome. We hope this paper provides a useful methodology for estimating population risk.

The estimation of population weighted average indoor radon levels requires statistically valid sampling methodologies that use a representative sample of occupied homes throughout the country. A literature review indicates that in many population weighted surveys, the sampling methodology may not have been designed to do this. This paper describes a simple, resource efficient methodology which produces statistically valid and reliable estimates based on a small scale sample that is representative of the population distribution. The resource efficient design of this study enables it to be repeated at frequent intervals providing for a longitudinal analysis of the population risk from indoor radon.

This survey was conducted in Ireland using 653 measurements and a representative sampling strategy to provide a baseline population weighted radon exposure for future comparisons. This study estimates the average population weighted indoor radon concentration in Ireland to be 97.83 Bq m⁻³ (95% Confidence Interval 90.69 Bq m⁻³ to 105.53 Bq m⁻³), and that there are an estimated 350 lung cancer cases and 255 deaths per year due to radon exposure. The mortality rate of 5.3 per 100,000 due to indoor radon, demonstrates that radon remains one of the highest preventable causes of death in Ireland.

2018年的一项估算表明，在进行了代表性ra调查的66个国家中，有226,057例由ra引起的肺癌死亡。这是一个令人震惊的数字，因为它仅来自66个国家/地区，因此低估了全球死亡人数。任何使各国能够进行代表性ra测量并更好地了解citizens遭受公民风险的研究都将受到欢迎。我们希望本文为估算人口风险提供一种有用的方法。

人口加权平均室内ra水平的估算需要统计上有效的抽样方法，该方法应使用全国各地居民住房的代表性样本。文献综述表明，在许多人口加权调查中，可能没有设计抽样方法来做到这一点。本文介绍了一种简单，资源高效的方法，该方法基于代表人口分布的小规模样本来产生统计上有效且可靠的估计值。这项研究的资源有效设计使其能够频繁地重复进行，从而对室内ra的人口风险进行了纵向分析。

这项调查是在爱尔兰进行的，使用了653次测量值和代表性抽样策略，以提供基线人群加权ra暴露量，以便将来进行比较。这项研究估计爱尔兰的平均人口加权室内ra浓度为97.83 Bq m ^-3（95％置信区间90.69 Bq m ^-3至105.53 Bq m ^-3），估计有350例肺癌病例和255例死亡每年由于ra暴露。室内indoor造成的死亡率为每10万人5.3％，这表明ra仍然是爱尔兰可预防的最高死亡原因之一。
