本文提供了第一个控制评估如何不同的信息材料解释氡的风险影响人们对这些风险的看法。使用小组研究，可以观察到所述的风险认知如何对有关室内氡浓度的信息和解释氡读数的小册子作出反应。研究结果表明，风险沟通政策可以有效地改变风险的看法。此外，他们有三个具体的含义氡政策：（1）公共官员不应该采取的战略，提供最低限度的风险信息，以避免公众过度恐慌的手段，因为这可能会产生相反的效果;（2）措施的有效性风险沟通将取决于如何教育和行为改变的定义;（3）没有量化信息的风险分类指导方针可能会导致人们将风险水平视为阈值，从而在他们对风险感知的微小变化的反应中造成人为的不连续性。
This article provides the first controlled evaluation of how different information materials explaining the risks from radon influenced people's perceptions of these risks. Using a panel study, it was possible to observe how stated risk perceptions responded to information about indoor radon concentrations and brochures explaining the radon readings. The findings indicate that risk communication policies can be effective in modifying risk perceptions. Moreover, they have three specific implications for radon policy: (1) Public officials should not adopt strategies that provide minimal risk information to the public as a means of avoiding undue alarm, for this can have the reverse effect; (2) measures of the effectiveness of risk communication will depend on how education and behavior change are defined; (3) categorical guidelines about risk without quantitative information can lead people to treat the levels as thresholds, creating an artificial discontinuity in their responses to small changes in risk perceptions.
