What is CBRN?

Introduction

CBRN stands for Chemical, Biological, Radiological, and Nuclear threats, which pose serious risks to human health and global security. The field of CBRN aims to understand, prepare for, and mitigate these threats.


Chemical Threats

Chemical threats involve toxic chemicals like nerve agents, chlorine, and sulfur mustard. These substances can be released intentionally or accidentally, affecting air quality, water supply, and food.

Real-World Examples: 

Sarin gas attack in Tokyo subway (1995)

Chlorine gas attacks during World War I

Biological Threats

Biological threats encompass bacteria, viruses, and toxins that can lead to diseases like anthrax, smallpox, and Ebola.

Real-World Examples:

Anthrax attacks in the United States (2001)

The global spread of H5N1 Avian Flu

Radiological Threats

Radiological threats involve the use of radioactive material to contaminate environments, commonly referred to as "dirty bombs."

Real-World Examples:

Radiological dispersal device scenarios (theoretical)

Chernobyl (industrial accident)

Nuclear Threats

Nuclear threats involve the use of nuclear devices, capable of causing mass destruction and long-term environmental damage.

Real-World Examples:

Hiroshima and Nagasaki bombings (1945)
