This book was released on 2009 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radon gas is a significant public health problem that contributes to some cases of lung cancer. This thesis analyzes and determines the potential degree of radon gas exposure hazard in Marquette County, MI, by combining multiple layers of geospatial data in a geographic information system (GIS). The combined data are processed and assessed for statistically significant spatial patterns and correlations among multiple variables. Household indoor radon gas samples from locations throughout Marquette Country are the basis of the project. The results of this study will add to existing radon gas hazard research. In Marquette County, I have identified predictors based on correlated spatial attributes among indoor radon gas measurements, census variables (including rural and vacant housing), and geological features (including bedrock type and aeromagnetism), as identified in the existing literature. This thesis specifies the problem of the study, describes the significance of the problem, presents a comprehensive background of the subject, presents a detailed description of the methodology used in the study, discusses results of the study, and presents future recommendations for radon gas research.

Book excerpt: Radon is a chemical element that is naturally occurring and is produced during the disintegration of uranium. It is a radioactive gas that is carcinogenic in nature. The majority of the Ohio State population residing in uranium shale localities and uranium laden soil is at greater risk of being exposed to higher indoor radon concentrations. According to the US Environmental protection Agency (EPA), a concentration greater than or equal to 4 pCi/l (picocuries per liter) is considered hazardous and needs to be acted upon. According to the World Health Organization (WHO), the threshold level is at 2.7 pCi/l. The fair treatment and involvement of all people regardless of race, income, nationality in the administration of environmental laws and policies is Environmental Justice (EJ). This study uses Ohio indoor radon concentrations and census demographic data of the year 2017 to identify vulnerable census tracts susceptible to EJ issues using Geographic Information System (GIS). Also, the degree of Social Vulnerability (SV) which is the measure of vulnerable population in a block group to the exposure of higher indoor radon concentrations is determined. Geographic Zoning Value (GZV) method is developed in the current study to estimate the mean concentrations of indoor radon in census tracts. The vulnerable locations concerning EJ issues are identified in the State of Ohio by plugging output from GZV to the EJSCREEN Method2017 and ZS Silverman Method 2012. Results from both the methods are collected, compared, and analyzed with the same goal of identifying EJ issues. The EJSCREEN Method 2017 uses EJSCREEN (Version 2019) [1] analysis and the ZS Silverman Method 2012 is used to develop the EJ index to determine the extent of injustice present in a given census tract using the analysis proposed by Silverman (2012) [2]. The results indicate that 95% of the State of Ohio has no significant environmental inequality for the year 2017 according to EJSCREEN Method 2017. Environmental Justice Hazard Score (EJHS) is used in ZS Silverman Method 2012 to determine the EJ and 87% of buffer zones fall under limited to moderate category (0 ≤ EJHS ≤ 14) and the rest falling under high (14

Available in PDF, EPUB and Kindle. Book excerpt: This book is specifically designed to serve the community of postgraduates and researchers in the fields of epidemiology, health GIS, medical geography, and health management. It starts with the basic concepts and role of remote sensing, GIS in Kala-azar diseases. The book gives an exhaustive coverage of Satellite data, GPS, GIS, spatial and attribute data modeling, and geospatial analysis of Kala-azar diseases. It also presents the modern trends of remote sensing and GIS in health risk assessment with an illustrated discussion on its numerous applications.

Download or read book Radon Levels and Surficial Geology Analyzed with Geographic Information Systems Chautauqua County New York written by Bryan Mentley and published by . This book was released on 2002 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: In November 1998 the Chautauqua County Health Department was awarded a $27,000 grant from the New York State health Department to partially fund a local indoor air radon testing and outreach program. The purpose of this program was to increase radon testing in individual homes, identify locations posing a high risk to radon exposure, and increase public awareness of the radon problem. A geographic Information System (GIS) was used as an aid to evaluate the spatial distribution of test data. Coordinates of each home tested were determined using two methods; coordinates for homes within the cities of Dunkirk, Jamestown and surrounding areas were calculated using address matching (i.e. geocoding), while coordinates for homes in the remainder of the county were determined using GPS surveying. A total of 953 radon measurements were taken at 863 homes throughout the county. Based on the 894-test data set (excludes duplicate samples), radon results ranged from 0.1 to 96.1 pCi/L, with an average concentration of 4.4 pCi/L and a standard deviation of 8.8. The relationship between surficial geology and radon levels was evaluated by comparing the radon test results coverage with the USGS Surficial Geology-Western New York State coverage. Results indicated that 47.8% of test in houses on coarse-grained sediment are above the USEPA action level (4.0 pCiL); whereas a only 16.1% of the tests in houses on fine-grained sediment are above the action level. This information was used to develop a map showing priority-testing areas in Chautauqua County. Future radon outreach and testing efforts will place a greater emphasis on testing homes in porous, coarse grained sediments (e.g., sand and gravel). -- Author abstract
