Health Risk Assessment is defined as...

• A. Process of identifying hazards, collecting accurate information, and characterizing risks.
• B. A decision making process to minimize exposure
• C. An estimate of exposure
• D. An identified health threat

Answer: (A)

Health risk assessment is a structured process to estimate potential adverse health effects from exposure to hazards. It involves identifying what hazards exist, gathering reliable information, and combining that data to characterize the level of risk—essentially linking what the hazard is with how people might be exposed and what dose would cause harm. This matches the description of a process that identifies hazards, collects accurate information, and characterizes risks. The other options describe separate ideas: risk management is the decision-making step to minimize exposure, exposure assessment focuses only on estimating how much people are exposed, and identifying a health threat is just recognizing a hazard without evaluating the risk.
