GPH 107: Environmental/ Chemical/ Radiation Emergency Response

Environmental, chemical, and radiation emergencies present complex and potentially invisible threats to population health. Industrial spills, toxic releases, nuclear incidents, and accidental exposures demand rapid assessment, specialised expertise, and coordinated containment.This chapter explores hazard identification, exposure pathways, toxicology, dose assessment, decontamination protocols, evacuation planning, risk communication, and long-term monitoring. It examines inter-agency coordination, regulatory oversight, and preparedness planning.Unlike infectious outbreaks, these threats may be silent and odourless, requiring measurement instruments rather than clinical suspicion alone. Effective response depends on preparedness infrastructure, clear communication, and evidence-based thresholds for action.In environmental emergencies, precision protects.Key Takeaways* Environmental emergencies require rapid hazard identification and containment.* Exposure assessment guides protective action.* Decontamination and evacuation protocols reduce risk.* Toxicology and dose–response principles inform response decisions.* Inter-agency coordination is essential.* Risk communication must be clear and transparent.* Long-term monitoring ensures sustained protection.
