Abstract
Population scientists, radon hazard prevention staff, geologists from a land-grant university, and economists from the USGS Science & Decisions Center collaborated to quantify the societal benefits derived from creating and disseminating radon risk potential maps. These maps were overlain on observed short-term home radon values statewide spanning over 20 years (N > 70,000) and outcropping geologic rock formations in Kentucky. We used available data to analyze the economic benefits of the maps on radon testing, radon mitigation, lung cancer incidence, years of potential lives lost, and healthcare cost savings adjusting for smoking rates. USGS scientists are applying value of information (VOI) techniques to estimate the economic impacts associated with lung cancer for scenarios with and without access to the radon potential maps. Results will be presented. There is an urgent need to communicate the value of geologic maps related to population health outcomes in light of increasingly complex scientific issues.

Abstract
A 3-year radon and health study was conducted using approximately 2000 occupied homes in VA, MD and DC over approximately 1000 square miles. Seasonal alpha-detectors and weekly charcoal detectors were used for indoor-radon measurements, with EPERMs used for drinking water. Home occupants provided the home location (radon vs. geology comparisons), home characteristics (radon vs. basement construction, size, HVAC system, water supply, etc.) and cancer experiences of family members (radon and time vs. cancer types). Higher indoor-radon tends to be in homes over sandy soil and acidic (granitic) soil, and in homes with larger basements, concrete block construction, heat pump HVAC systems, dry sump-pump crocks, etc.; while soft-tissue cancers (leukemia, brain, breast, liver, kidney) were more common in homes with waterborne radon above 2000 pCi/L. No correlation was found between waterborne radon and indoor radon, indoor radon and season-of-year, indoor radon and lung cancer, and drinking water radon and stomach cancer.

Abstract
Most radon induced-lung cancers occur in those also exposed to tobacco smoke. We evaluated the impact of disseminating county-level radon map infographics using a Train-the-Trainer approach and free radon test kits. User-friendly geological map infographics were created and disseminated; 42 public health professionals participated in Train the Trainer workshops. Trainers received presentation slides and free radon test kits for distribution. Map infographics were posted to our website. On average, 22 test kits were distributed per trainee for a total of 903; 12% were deployed. Perceived barriers to distribution will be presented. There was no association between position or type of training on number of test kits distributed. There were 1,388 website hits to the map infographics. There was a marginal increase in trainees’ perceived synergistic risk (radon + tobacco smoke) at post-training. This approach engaged the community, increased radon testing, and may decrease barriers to radon education and home testing.

Abstract
 The association between exposure to radon, tobacco smoke, and lung cancer is established; not as much is known about the immediate health effects of radon exposure. We examined the relationship between levels of radon and secondhand smoke (SHS) in the home and respiratory symptoms, controlling for smoking status and COPD diagnosis. The pilot study was a cross-sectional design with a convenience sample of 71 homeowners who had tested their homes for radon and SHS as part of a larger environmental risk reduction study. Of the 71 participants, 27 homes tested high for radon (> 4.0 pCi/L); 44 tested high for SHS. Logistic regression showed that radon level was the only significant variable associated with presence of respiratory symptoms, controlling for smoking status and COPD diagnosis. This study adds important information to the literature and indicates that more research is needed to understand the immediate health effects of radon exposure.

 Abstract
 Kemling Cave is located in Dubuque County, Iowa.  It is a single-entrance cave with 3.51 km of surveyed passage.  The entrance is gated, but done so in a manner that does not impede air exchange between the cave and the surface environment.  Past work has shown that measurement of radon activity as a function of time in this cave displayed an extreme degree of variability.  In this work, follow-up studies were designed and carried out to measure radon activity in parallel with a number of other environmental parameters, seeking to find which of the parameters had the strongest correlation with the radon activity.

Abstract
Radionuclides from three naturally occurring decay series (headed by 238U, 230Th, and 235U), have long been known to be present in groundwaters in Georgia. In 2010, routine surveillance of drinking-water testing revealed uranium concentrations exceeded the U.S. Maximum Contaminant Level (30 ppb) in private wells in central Georgia. Since they are in the same 238U decay series, high levels of uranium in well water may be associated with elevated levels of dissolved radon gas. Drinking water that contains high levels of these contaminants can have adverse health consequences, though definite relationships of those health issues with uranium and radon in drinking water have not been established. This paper provides an overview of our testing, mapping programs, and public education programs for tracking and mitigating uranium and radon in Georgia well waters. It also sheds some lights on the temporal variation of these two contaminants in well waters and their interrelationships.

Science & Research: Investigation Radon Decay Products: Case Studies and Review of Key Scientific Literature
Investigating Radon Decay Products: CASE STUDIES and review of key Scientific Literature

Abstract 
Alpha radiation from radon decay products (RDPs) is the second leading cause of lung cancer in the United States. The relationship between RDP working level (WL) and radon concentration was investigated in several high radon environments where standard mitigation techniques are not feasible. By increasing air circulation through non-invasive methods, a decrease in RDP WL was observed. However, it was discovered that existing conditions within the study areas were already maintaining RDPs well below 0.02 WL. As RDPs are a notable health hazard and there exists locations where radon mitigation is impractical, further studies are needed to examine the effectiveness of long-term RDP mitigation techniques and to verify the equilibrium factors. In conjunction with this case study, a literature review of key research investigating RDPs is presented to help increase RDP awareness.

Abstract
The U.S. DOD sponsored research through the ESTCP Program for improved understanding of mitigation systems for radon and volatile organic compounds under project number ER2013-22.  This presentation summarizes the findings of the 5-year study.  For large buildings, the research indicates that significant improvements in cost-effectiveness can be achieved using a few new lines of evidence and a spreadsheet model.  Lines of evidence include steady vacuum versus radial distance from a suction point, transient vacuum measurements (change in vacuum vs time in response to turning the fan on or off) and fitting data to equations to calculate the transmissivity (T) of the material below the floor slab and the leakance (B) of the floor slab.  Helium tracer testing to measure flow rates below the slab and mass removal rate monitoring provide added value for system design and monitoring.  Case studies of one residence and two commercial buildings will be included.

Abstract
Our papers in 2016 and 2017 Symposia discussed optimum sampling and analysis methods for radon in waterThis presentation discusses quality assurance. The counting efficiencies of multiple liquid radium standards purchased from a commercial manufacturer produced inconsistent and unacceptable counting efficiencies; thus, their use in the analysis appeared questionable. Duplicate analysis of radon in 142 well water samples mostly yielded relative percentage deviation (RPD) ≤15 and seldom >15. However, >15 RPD was associated with the presence of an air bubble in one of the duplicate samples. Repeated analyses of two radon proficiency-test samples, regenerated at 40 to 60 day intervals over a period of two years, consistently yielded acceptable precision (based on the duplicate analyses) and accuracy (closeness to the theoretical radon concentration). Thus, a proficiency testing for radon in water is a valid and valuable option, and should be part of programs that analyze radon in water.

Abstract
From the analysis of about 100,000 radon measurements in Swedish dwellings stored in the database of Radonova, it has been found that the number of dwellings above the reference level of 200 Bq/m3 (5.4 pCi/l) has decreased a lot for new buildings. The number of single-family houses with building year 2014-2016 with radon levels above the reference level was only about 2 % which can be compared with about 30% for houses built 1950-1980. These data show the importance of good building practice. The development in building technique which can have influenced this improvement will be discussed. Similar data will also be presented for multi-family houses as well as data showing how the radon levels in houses built around 2005 have changed from measurement at that time until now.

Abstract
Researchers at the National Research Council (NRC) of Canada have been conducting experimental studies related to radon control in buildings since 2011, in collaboration with Health Canada’s National Radon Program. The presentation outlines the research outcomes covering the topics ranging from the impact of active soil depressurization on heating energy consumption and indoor environment, leakage through radon control fan enclosure, performance of passive radon stacks in Canadian homes, to the effectiveness of using heat recovery ventilator for radon control in airtight houses. In order to verify the effectiveness of sub-slab air barrier systems in reducing radon ingress, the NRC has developed the Radon Infiltration Building Envelope Test System (RIBETS) and Radon Diffusion Test Chamber (RDTC). The paper will focus on the testing from the RIBETS and the RDTC, summarizing the Radon Diffusion Coefficient and Radon Resistance results measured from 10 building materials that are used beneath concrete slabs.
