Predictive analysis and mapping of indoor radon concentrations in a complex environment using kernel estimation: An application to Switzerland

Purpose
The aim of this study was to develop models based on kernel regression and probability estimation in order to predict and map IRC in Switzerland by taking into account all of the following: architectural factors, spatial relationships between the measurements, as well as geological information.

Highlights
•Kernel regression was used to map indoor radon concentration in Switzerland.
•Our model explains 28% of the variations of radon concentration data.
•Maps were generated considering different architectural elements and geology.
•Maps showing the local probability to exceed 300 Bq/m3 were proposed.
•We developed a confidence index to assess the reliability of the probability map.

Predictors of Indoor Radon Concentrations in Pennsylvania, 1989–2013

Background: Radon is the second-leading cause of lung cancer worldwide. Most indoor exposure occurs by diffusion of soil gas. Radon is also found in well water, natural gas and ambient air. Pennsylvania has high indoor radon concentrations; buildings are often tested during real estate transactions with results reported to the Department of Environmental Protection (PADEP).
Objectives: To evaluate predictors of indoor radon concentrations.

Methods: Using first floor and basement indoor radon results reported to the PADEP between 1987-2013, we evaluated associations of radon concentrations (ln-transformed) with geology, water source, building characteristics, season, weather, community socioeconomic status, community type and unconventional natural gas development measures based on drilled and producing wells.

Prince George: Community-Wide Radon Testing Study Results

Radon is a colourless, odourless gas that is found in soil, rocks and water. Radon has been identified as the second leading cause of lung cancer in Canada. Health Canada estimates as many as 16 percent of lung cancer deaths can be attributed to radon exposure. Most of the lung cancer risk posed by radon happens in homes.

Many homeowners want to know what the radon level is in their home. In January 2014, the BC Lung Association launched Canada’s largest single community radon testing project in Prince George, BC. This project serves to answer the radon level question for homeowners and tenants, and provide average radon level results for all testing tracked by Postal Code Area (PCA).

The Project offered free radon test kits to 2,000 Prince George homeowners and tenants to test indoor radon levels in their homes. A total of 1,436 test kits, or 71.5 percent of test kits distributed, were returned from across the City.

Abstract:
For nearly 20 years the Department of Health has conducted programs to assist in the measurement
and reduction of indoor radon concentrations in 186 schools located primarily in Zone 1 areas of
New York State. Although many schools had few or no rooms containing radon above 148 Bq/m3,
some rooms had >740 Bq/m3 and remediation techniques were utilized to reduce exposure. Short-termradon measurements in the schools showed little correlation to basement and first-floor radon
results from single-family homes in the towns.
