    ​​​Radiological Dispersion Device

    The primary purpose of terrorist use of a Radiological Dispersion Device (RDD) is to cause psychological fear and economic disruption. Many factors determine the size of the affected area and level of destruction caused by an RDD such as type, quality and quantity of radioactive material and weather conditions. The affected area could be placed off-limits to the public for several months during cleanup efforts.
