The ongoing US–Israel–Iran conflict, now in its fourth week, has raised concerns about unconventional escalation options, including the potential use of a “dirty bomb,” formally known as a Radiological dispersal device. While such a device is far less destructive than a nuclear weapon, it can still cause widespread disruption through radioactive contamination and long-term environmental impact.
A dirty bomb combines a conventional explosive with radioactive material, dispersing contaminated particles over a wide area when detonated. Unlike a nuclear weapon, it does not involve a nuclear chain reaction or massive blast. Instead, its primary effect is contamination, with the explosion itself causing immediate injuries and damage, while radioactive dust and smoke can spread further and pose health risks over time. Exposure in severe cases may lead to conditions such as Acute radiation syndrome, while prolonged exposure can increase the risk of cancer and other chronic illnesses.
From a technical perspective, building such a device is considered feasible, as it does not require highly enriched uranium or advanced nuclear weapons capability. Radioactive materials used in medical or industrial applications can potentially be repurposed. Iran’s stockpile of uranium enriched to around 60% is not sufficient for a nuclear weapon, but experts suggest it could still be used in a radiological device, adding to concerns about its potential capabilities.
Despite this, most analysts believe that the likelihood of Iran deploying a dirty bomb remains low under normal conditions. Such a move would likely trigger severe military retaliation, global condemnation, and diplomatic isolation, including strained ties with key international partners. However, in extreme scenarios where leadership perceives an existential threat, unconventional options could be reconsidered as a means of retaliation or deterrence.
If such a device were used, its primary objective would likely be disruption rather than mass casualties. Potential targets could include densely populated urban areas, economic centres, or strategic chokepoints such as major shipping routes. The resulting impact would extend beyond physical damage, causing widespread panic, economic disruption, and long-term contamination that could affect infrastructure, trade, and public health.
Overall, while the possibility of a dirty bomb introduces a serious dimension to the conflict, there is no confirmed evidence that such a device has been developed or will be used. The concern remains largely theoretical, but it underscores the risks of escalation in a conflict that is already marked by intense military activity and geopolitical instability.
