Chapter 3 in the textbook, Understanding Environmental Health, (3.1 Identifying Acceptable Risk) presents the concept of risk communication. Review this section of the text, paying attention to the explanation of why public perceptions of risk may be more or less serious depending on the characteristics of the hazard.
Complete the following:
Think of an environmental risk that occurs in nature. You can look ahead to Chapter 4, “Living with Nature,” if needed. Briefly describe the risk.
Assess the likelihood of public outrage related to this natural risk based on its characteristics and the outrage-related features listed on page 47.
Why is it important to recognize the likelihood of outrage when communicating with the public about a risk?
Be sure to respond to at least one of your classmates' posts.
Sample Answer
. Selected Environmental Risk: Radon Gas
Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil and rock. It is colorless, odorless, and can accumulate to dangerous levels inside homes, especially in basements. According to the text, it is the second leading cause of lung cancer, posing a significant "natural" risk to human health.
Assessment of Public Outrage
Based on the features listed on page 47, Radon typically generates low public outrage, despite being a high-level hazard. Here is why:
Voluntary vs. Involuntary: While homeowners don't "choose" to have radon, the decision to test and mitigate is voluntary. Risks perceived as voluntary generally cause less outrage.
Natural vs. Industrial: Radon is "natural." The public tends to be less outraged by risks originating from the earth than by those caused by industrial pollution or human negligence.
