This book investigates the core question of how the public can accurately assess the actual level of danger posed by various environmental health hazards. Authors Inge F. Goldstein and Martin Goldstein, both established experts in epidemiology and public health, utilize a framework of scientific methodology to demystify complex environmental data. They argue that by understanding the mechanisms of risk assessment, individuals can move beyond alarmist headlines to make rational, evidence-based decisions regarding their health.

Experts and educators frequently cite this work as a clear, accessible primer for understanding the intersection of environmental science and public policy. Readers often note that the prose maintains a high level of academic rigor while remaining approachable for those without a specialized scientific background.
