Radonriskit

Radonriskit is a web-based decision-support resource that estimates residential radon exposure risk. The tool is intended for homeowners, renters, educators, and public health professionals to understand potential radon concerns in a dwelling and to guide testing and mitigation decisions. Radonriskit does not measure radon directly; it produces an indicative risk assessment by combining user-provided information about a home with regional radon prevalence data.

Users input location, building type, foundation, year built, and ventilation characteristics. The output includes an estimated indoor radon concentration range, a risk category (low, moderate, high), and recommendations such as radon testing, improving ventilation, sealing, or considering a mitigation system. The tool also provides general guidance on testing protocols and mitigation options.

Methodology relies on integrating publicly available regional radon estimates with a simplified exposure model that accounts for building features. It presents uncertainties and emphasizes that results are educational and not a substitute for professional measurement or medical advice. Data sources are cited within the tool and updated periodically.

Limitations include input accuracy and regional data availability. Results should be used to initiate conversations with qualified testers or mitigation professionals rather than as definitive measurements or formal risk assessments.
