What is the main purpose of a Radiological Dispersal Device?

To create a low-level radioactive environment
To spread radioactive contamination
To protect against radiation exposure
To illuminate areas with radiation

The correct answer is: To spread radioactive contamination

The main purpose of a Radiological Dispersal Device (RDD), commonly referred to as a "dirty bomb," is to spread radioactive contamination over a wide area. Unlike nuclear weapons that produce a massive explosion, an RDD combines conventional explosives with radioactive materials, utilizing the explosion to disseminate these materials into the environment. This method aims to cause panic, disrupt societal functions, and pose health risks due to exposure to radiation. The intent is not to create a low-level radioactive environment or illuminate areas, but rather to spread contamination to affect the populace and infrastructure. Thus, the answer that identifies the primary function of an RDD as spreading radioactive contamination accurately reflects its intended use in a security threat context.
