What does RDD mean in UNCLASSIFIED

A typical radiological dispersal device consists of two components - a radioactive source material, such as Cesium-137, and a container that holds the source material. The container can be made from plastic, metal or other materials, depending on its intended use.

An RDD works by releasing particles of radioactive material into the air once it's activated. These particles become aerosolized, allowing them to spread over a wide area and cause widespread contamination. Depending on the size and construction of the device, it can have short- or long-term effects on human health and the environment.

Generally speaking, only governments and terrorists use radiological dispersion devices; they are not available commercially and there is no legitimate use for them outside of research purposes. Governments may use them for testing protective measures against nuclear weapons attacks, while terrorists could use them as part of a larger attack plan with malicious intent.

The damage caused by an RDD depends on how much radioactive material was released and how far it traveled before dissipating in the atmosphere; however, most experts agree that any amount of exposure to radiation increases one's chances for developing cancer or experiencing other types of illnesses later in life. Additionally, prolonged exposure to radiation levels higher than normal can lead to long-term environmental damage such as soil contamination or water contamination in nearby bodies of water.

One way you can tell if you're at risk from an RDD is if you notice symptoms such as vomiting or nausea shortly after being exposed to radiation levels higher than normal; however, these symptoms won't manifest immediately after exposure - often it takes weeks or months before symptoms appear due to the latency period associated with radiation sickness. Additionally, if you live near a place where suspicious activity has been reported involving nuclear materials or devices (such as military sites), then you should take extra precautions to ensure your safety in case something happens there that could result in radiation spillage or contamination.
