CBRNE

CBRNE (pronounced "SEE-burn") is an acronym for Chemical, Biological, Radiological, Nuclear, and Explosive materials. These materials are very dangerous, and can hurt many people. When they are used on purpose, CBRNE materials are weapons of mass destruction. However, CBRNE events can also happen accidentally.[1]

A report from the White House in 2011 said "there is no greater danger to the [United States] than a terrorist attack with a weapon of mass destruction."[2] Because CBRNE weapons are so dangerous, countries around the world are working on preventing CBRNE attacks, and learning how to react to them if they do happen.[3]

Types of CBRNE weapons[change | change source]

Chemical[change | change source]

The main types of chemical weapons are:[3]

International laws make it illegal to use chemical weapons. However, terrorists have ignored these laws. For example, in 1995, terrorists attacked the subway in Tokyo, Japan, with sarin.[2]

Biological[change | change source]

The goal of biological weapons is to get as many people sick with infectious diseases as possible. Types of biological weapons include:[1][3]

In 2001, a terrorist used a biological weapon against the United States by sending letters filled with anthrax through the mail to many different people.[1] Ricin has also been sent through the mail as a biological attack.[2]

Radiological[change | change source]

A radiological weapon is any kind of weapon that spreads radiation. For example:

In 2006, Alexander Litvinenko, a former Russian spy, was murdered when someone put polonium-210, a radioactive material, in his food.[1]

The White House's report says that there is radiological material all around the world that is not guarded.[2]

Nuclear[change | change source]

A nuclear weapon releases a huge amount of energy in a nuclear explosion. Nuclear weapons can kill everyone in a city, and make many other people who survive sick with radiation poisoning.

Although many countries have tested nuclear weapons, they have only been used as weapons of mass destruction twice. During World War II, the United States dropped two nuclear bombs on the Japanese cities of Hiroshima and Nagasaki. In Hiroshima, the nuclear bomb destroyed 4.7 square miles (12 km2) of the city,[4] and killed 60,000 to 80,000 people right away. More people later died from radiation sickness and cancer caused by radiation, so historians think about 135,000 people were killed by the one nuclear bomb that hit Hiroshima.[5]

In Nagasaki, the nuclear bomb created about 3,900 °C (7,050 °F) of heat, and winds as fast as 1,005 km/h (624 mph).[6] It killed somewhere between 39,000 and 80,000 people.[7]

After these bombings, many countries agreed to get rid of their nuclear bombs. However, some countries still have nuclear bombs, and there is nuclear material around the world that is not guarded.[2]

Explosives[change | change source]

Explosive weapons include things like regular bombs and improvised explosive devices (IEDs). Terrorists have often used IEDs to kill and injure soldiers in Iraq. In some other countries, like Israel, terrorists attach bombs to their bodies and make them explode in public places, killing many people as well as themselves. During the Vietnam War, the United States often used napalm ("liquid fire") as part of their bombs. They also mixed it with gasoline and phosphorous to make it more explosive and sprayed it directly from boats and helicopters.

During the 2013 Boston Marathon, two terrorists used explosives to kill three people and hurt 264 others at the Marathon's finish line.[8]

During the November Paris Attacks, a group of terrorists known as ISIS brought bombs to public places and exploded them.
