Cost-Effectiveness Analysis of Public Education and Incentive Programs for Controlling Radon in the Home

摘要

The objective of the study was to evaluate the cost-effectiveness in Illinois of five radon public education and incentive program options. Programs evaluated included (1) no program, (2) a toll-free 'hotline' and information packet, (3) free short-term monitors, (4) free confirmatory monitors, and (5) low interest loans. Existing literature and expert opinion were used to estimate program costs and public responses under the various programs. Computer simulation, with Monte Carlo sampling, was used for uncertainty and sensitivity analysis. The cost-effectiveness model was analyzed based on assumed radon exposures to Illinois citizens. Results for standard conditions indicate that budget levels under approximately $30,000 do not warrant a radon education and incentive program. For budget levels of approximately $30,000 to $1 million, program 2 was most effective, and program 3 was most effective above this level. Sensitivity analyses indicate the results are relatively insensitive to input variable assumptions with the exception of public response estimates. Study results suggest that all of the programs evaluated are likely to be relatively ineffective. Considerable improvement may be possible using more innovative approaches to public education.
