Abstract 
Radon, which is one of the major pollutants in indoor environments, is a radioactive gas naturally formed during the decay of radium, which is found in places such as soil, building materials, and groundwater. In this study, we conduct to evaluate the contribution rate of radon concentration by radon exhalation from building materials in real-life environments.
   To control the effect of radon exhalation from the soil, measurements were conducted upper sixth floors. In order to evaluating radon concentration, in-situ method was used to measure radon exhaled from building material and indoor radon concentration was also measured with E-perm in same time.
Based on the results obtained in this study, it is expected that it will be used as basic data for setting the standard of radon exhalation from building materials in the future.

                                                                                                                   Abstract
This paper will discuss current and proposed American (AARST) and Canadian (CARST) protocols regarding radon measurements for real estate transactions.  Expectations and understanding of the real estate industry in both countries will also be presented; as will general practice within the “home inspection” profession; along with mitigation and escrow implications.
 A method will be proposed to improve the reliability of real estate transaction radon measurements. A key feature of the method is the deployment of three “listed” detectors (any type capable of providing short term results) in nominally the same physical location, such that they are subject to equivalent temporal, seasonal, and environmental conditions over the course of the measurement period. The three resulting radon concentration measurements are then analyzed using the Dixon Criterion, a statistical method specifically designed for maintaining precision in small data sets by providing a statistical basis for the rejection of an “outlier” or suspect result.

Abstract
How is the State of Utah creating advocacy with real estate companies?  Radon is now listed on the Buyer-Due-Diligence-Checklist and has created a positive relationship for the radon educators and the real estate agents. The purpose of this presentation is to help other states and the industry to take the steps needed to create positive relationships with real estate agents in their states.

Abstract
 The US Environmental Protection Agency and states encourage building radon resistant (ready) new homes (RRNC). The Florida Radon Program evaluated a home built following RRNC practices in Tallahassee.  The home in question was measured with the passive system in three occasions.  Once with the passive system operating normally; next, with the system capped; and finally simulating a fan on the system by using a shop-vac at the end of the radon exhaust pipe on the roof.  Data indicate the system is producing reductions on the radon levels from 25% to 99% depending on the method used.

Abstract
In this study, concentrations of radon in residential buildings were investigated in order to establish the pattern of variation within the buildings in these environments. The target rooms were the bedroom, bathroom/ toilet, living room and kitchen. One hundred and thirty-seven (137) rooms were selected using multi-stage sampling protocol. Solid state nuclear track detectors, CR-39, were employed for the measurement so as to obtain average radon concentration in each room. Radon concentrations vary from 3.63 – 12.17 Bq/m3, 3.09 – 11.62 Bq/m3, 3.43 – 13.26 Bq/m3, and 4.09 – 13 Bq/m3 with mean of 6.75 ± 0.09, 6.89 ± 0.08, 6.44 ± 0.09 and 7.43± 0.09 Bq/m3 respectively in the bedrooms, bathrooms/ toilets, living rooms and kitchens. Therefore, the pattern of radon concentration variations observed in this study is of this order:  bedroom < bathroom/toilet < kitchen < living room.

Abstract
 A team of geologists, nurses, statisticians, and health educators collaborated to create lay-friendly, county-level maps showing varying radon potential using the novel concept of danger to non-technically communicate risk. The maps were created in 2016 by correlating observed radon values from short-term residential test kits with rock types, and have been widely circulated in the state in an attempt to create awareness and increase residential radon testing. We are in process of validating the radon-potential maps in the field using a portable laboratory grade electronic radon detector. We are taking real-time radon measurements with a soil-gas probe to help identify specific geologic units that are prone to high radon production. Data will be used to complement the maps in areas with little data. We will present preliminary data on radon in groundwater using water attachments from the radon detector

Abstract
 
To analyze the use of 3 x 4 aluminum downspouts for the external venting system on residential Radon mitigation systems rather than PVC pipe to improve aesthetics.  Explore the effects air flow volume, determine if aluminum downspout allows an excessive amount of radon gasses and/or moisture to escape through the seams.  Specifically, can aluminum downspout be used without radon re-entry into to the home and/or moisture damage to the home?

Abstract
The revision of the Indoor Air Quality Management Act of Korea of the new housing complex changed the radon management perception and mitigation system. Therefore, the existing imported and installed radon barrier membrane was developed for the domestic environment.
Recently graphene polymer composite materials have been paid much attention for their potential applications in various areas. Although several studies of epoxy materials based on graphenes were reported, there are still needs in development of new polymer composites. Despite the report of araldite epoxy as a bisphenol type, there has been no report on its composites with graphene materials to the best of our knowledge. In this work, we report araldite 506 epoxy resin graphene composites. The potential application for the radon gas barriers will be tested.
As a result, radon barrier membrane is made of graphene polymer composite materials and commercialization is tried after confirming diminishing efficiency of mitigation system.

STATIONARY ONLINE RADON MONITORING WITH ALPHAGUARD

Bertin GmbH, Frankfurt a.M., Germany
froessler@saphymo.de
Abstract
Stationary radon monitoring with remote data access is more and more important today, for radiation protection purposes but also for applications using radon as a tracer. For example, in high seismological risk level areas the radon in soil gas can be used as a tracer for seismic activities. The remote online monitoring of the radon in soil gas enables a considerable improvement of the early detection of seismic activities. In mines or other industries with increased radon levels, radon monitoring stations are used for radiation protection purposes. Based on real-time measurement data fast actions can be taken, such as by adapting the ventilation to reduce the radon exposure of workers in case of an exceedance of reference or threshold values. With the AlphaGUARD and its accessories complete measuring stations can be provided for remote online monitoring of the radon concentration in air, water and soil, proven in numerous existing applications.
