PaRadonGW.shp - Evaluation of Radon Occurrence in Groundwater from 16 Geologic Units in Pennsylvania, 1986–2015, with Application to Potential Radon Exposure from Groundwater and Indoor Air

This dataset documents results from 1,041 groundwater samples collected during 1986‒2015 from 16 geologic units in Pennsylvania associated with 25 or more groundwater samples with activities or concentrations of radon-222. Radon-222 is hereafter referred to as “radon.” These 16 geologic units were evaluated in an effort to identify variations in radon concentrations and to classify potential radon exposure from groundwater and indoor air. This dataset was developed for the Pennsylvania Environmental Public Health Tracking (PAEPHT) Program to describe the spatial distribution of radon concentrations in groundwater in Pennsylvania and to illustrate data gaps that exist throughout the State. The PAEPHT Program is part of the National Environmental Public Health Tracking Program funded by the Centers for Disease Control and Prevention (CDC) to improve public health by providing science-based information about the presence of and trends in environmentally related diseases. A focus area for the PAEPHT Program is that of understanding the occurrence of radon concentrations in groundwater and indoor air across the State. This dataset representing radon concentrations in groundwater and describing potential radon exposure from groundwater and indoor air according to geologic units may be used for resource decision-making and risk assessment. This dataset is available from the U.S. Geological Survey (USGS) at https://doi.org/10.5066/F7PR7T74. The companion publication describing the study is at https://pubs.er.usgs.gov/publication/sir20175018 [https://doi.org/10.3133/sir20175018] and is intended to be available through the online databases of the CDC and the PAEPHT programs [http://doh.pa.gov/epht].

本数据集收录了1986年至2015年间，从宾夕法尼亚州16个地质单元中采集的1041份地下水样品的检测结果，上述地质单元均对应至少25份带有氡-222（radon-222）活度或浓度检测数据的地下水样品。本文后续将氡-222简称为“氡”。本次研究对这16个地质单元开展评估，旨在厘清氡浓度的分布差异，并对地下水与室内空气中潜在的氡暴露风险进行分级。本数据集由宾夕法尼亚州环境公共健康追踪项目（Pennsylvania Environmental Public Health Tracking, PAEPHT）研发，用于描述宾夕法尼亚州地下水中氡浓度的空间分布特征，并阐明全州范围内存在的数据空白。PAEPHT项目隶属于由美国疾病控制与预防中心（Centers for Disease Control and Prevention, CDC）资助的国家环境公共健康追踪项目，该项目通过提供与环境相关疾病的发生情况及流行趋势的科学依据，助力公共健康事业发展。PAEPHT项目的核心研究方向之一，是探明全州范围内地下水与室内空气中氡浓度的分布情况。本数据集收录了地下水中的氡浓度数据，并依据地质单元刻画了地下水与室内空气中潜在的氡暴露风险，可用于资源决策与风险评估工作。本数据集可通过美国地质调查局（U.S. Geological Survey, USGS）的以下链接获取：https://doi.org/10.5066/F7PR7T74。本研究的配套学术成果发表于以下链接：https://pubs.er.usgs.gov/publication/sir20175018 [https://doi.org/10.3133/sir20175018]，该成果预计可通过美国疾控中心及PAEPHT项目的在线数据库（http://doh.pa.gov/epht）获取。
