Horizon Season 2003 Episode 4 Dirty Bomb

Horizon is a groundbreaking and long-running documentary series that explores the latest developments in science and technology. It has been informing and entertaining viewers since the 1960s, and its 2003 season was no exception. In episode 4 of that season, titled "Dirty Bomb," Horizon examines the potential consequences of a terrorist attack that uses a radioactive "dirty bomb."

The episode starts by laying out the threat of a dirty bomb, which is a relatively simple device that combines explosives with radioactive material. Though the resulting explosion may not be as destructive as a traditional bomb, it can scatter radioactive particles over a large area, potentially contaminating buildings, streets, and people. The episode explains how terrorists could obtain such material, either by stealing it from a hospital or research facility or by buying it on the black market.

Next, "Dirty Bomb" considers the possible scenarios of a dirty bomb attack, using computer simulations and real-world examples. For instance, the episode shows how a bomb containing just a small amount of radioactive isotope could shut down the whole of Manhattan for days. It also analyses the impact of a hypothetical attack in central London and compares it with the aftermath of the 9/11 attacks. The episode presents a bleak picture of the potential devastation and chaos that such an attack could cause.

Having painted this worrying picture, Horizon explores the measures that are being put in place to prevent and respond to a dirty bomb attack. It features interviews with experts from various fields, such as nuclear physics, counter-terrorism, and emergency management. The episode shows how the authorities are using technology and intelligence to detect and intercept attempts to acquire radioactive material, while also preparing for the worst-case scenario. This includes training first responders, developing emergency plans, and deploying radiation detectors.

Lastly, Horizon asks whether the fear of a dirty bomb attack is justified, or is it just another example of the media hyping up a rare and unlikely threat? The episode presents both perspectives, interviewing terrorism experts who argue that the risk is real and increasing, as well as scientists who claim that the health risks of a dirty bomb are relatively low, and the panic it could incite is more damaging than the radiation itself.

Overall, "Dirty Bomb" is a thought-provoking and informative episode that sheds light on a little-discussed but potentially catastrophic threat. It raises questions about how to balance security and freedom, how to protect the public without spreading unnecessary fear, and how to prepare for the unknown. As always, Horizon presents a factual and impartial view on both sides of the argument, allowing viewers to draw their conclusions about the alarming topic.
