Can Israel's attack on Iran's nuclear assets lead to an explosion or radiation leak?
Israel has struck major nuclear facilities in Iran this morning, including the country's Natanz nuclear-enrichment complex, in what it said was 'pre-emptive military action' aimed at thwarting Iran's attempts to build nuclear weapons.
These strikes may be a major setback for Iran's atomic capabilities, and have the potential to trigger a full-blown war in the Middle East. But as of now, the risks of nuclear disaster involving an explosion or a major radioactive leak are very low. Here's why.
First, some context
Israeli opposition to Iran's nuclear programme is not new. Neither are its attempts to thwart Tehran from developing atomic weapons.
The immediate trigger for the attack, however, was an adverse resolution by the Board of Governors of the International Atomic Energy Agency (IAEA) which declared that Iran has been non-compliant with its non-proliferation obligations — the first such resolution in two decades. The resolution, moved on Wednesday, comes on the back of an IAEA investigation which found that Iran was conducting 'secret nuclear activities' at three locations.
Notably, Israel's escalation also comes ahead of the sixth round of nuclear negotiations between Iran and the United States, which were scheduled to take place in Muscat this Sunday. The escalation is likely to tank ongoing N-talks between the two countries which seek a deal that would prevent Iran from developing nuclear weapons in exchange for sanctions relief.
Israel's main target
Israel's primary target was the Natanz Nuclear Facility, located in Isfahan province in central Iran. Natanz is the country's main uranium enrichment facility, where Iran has produced the vast majority of its nuclear fuel.
Enrichment is the process through which uranium-235, which is used for producing nuclear weapons, is extracted from naturally occurring uranium which is primarily of the uranium-238 variety. Natanz stores nuclear material of different formulations, including both enriched and unenriched uranium, and centrifuges which carry out the enrichment.
It is still too early to know how much damage Israel did. The entire Natanz facility, unlike Iran's other major enrichment facility in Fordow in the northern province of Qom, is not deeply buried. But the halls in which the centrifuges are kept, where the uranium is enriched, are said to be deep underground in the Persian desert and protected by highly reinforced concrete.
But even if Israel did hit the facility, a major nuclear calamity is unlikely. Simply hittin nuclear material or equipment with conventional weapons does not lead to a nuclear explosion or a widespread radiation leak.
What cannot be ruled out, however, are the chances of a localised dispersal of radioactive substances within the facility.
'It all depends on the configuration of nuclear material stored at the facility. If the nuclear material and explosives are kept separately, there isn't much danger of an explosion or leak, even if there is a direct hit on the nuclear material,' Anil Kakodkar, former head of India's Department of Atomic Energy, told The Indian Express.
'The strikes are likely to result in a dispersal, or the spread, of nuclear material into the environment. But this is likely to remain restricted within the facility or the place of the attack,' he added. Even if Israel were to have hit assembled nuclear weapons, the result is more likely to be a 'radiation leak' than an 'organised explosion', according to Kakodkar.
Why this is the case
Triggering a nuclear explosion, the kind atomic weapons are meant to bring about, requires a very precise set of processes to be followed, and a very specific initiation. All nuclear weapons also have inbuilt safety mechanisms to prevent an accidental detonation.
The Israeli attack on Iran's nuclear facilities, therefore, is unlikely to result in a nuclear explosion or a major radiation leak, but could certainly be a health hazard to people working within the facility and in the localities immediately outside.
Similar fears of a nuclear accident have prevailed in the Russia-Ukraine war as well, particularly when Ukraine's Zaporizhzhia nuclear power plant had got caught in the fighting. The plant did suffer some damage, but even in that case, a major nuclear accident was unlikely.

2 F-5 jets downed, key military sites hit: Israel gives 24-hour recap; shares video of strikes on Iran
The Israel Defense Forces (IDF) on Sunday said it had destroyed two Iranian fighter jets and eight ballistic missile launchers in a sweeping overnight operation that targeted dozens of military installations across Iran. Tired of too many ads? go ad free now The strikes, carried out by 20 Israeli fighter jets, reportedly hit key sites including Dezful and Isfahan airports. According to the IDF, the Israeli Air Force bombed two Iranian F-5 fighter jets at Dezful Airport, while missile launchers prepared for imminent strikes on Israel were also neutralised. 'This morning, the IAF struck missile launchers ready to launch toward Israeli territory, soldiers in the Iranian Armed Forces, and swiftly neutralised the launchers that launched missiles toward Israel,' the IDF said in a statement. Additional targets included explosive production sites, weapons storage and air defence systems. Military infrastructure at Isfahan Airport was also hit to prevent the Iranian Air Force from using the facility. The escalation came just hours after the United States entered the fray, striking three nuclear sites in Iran — Fordo, Isfahan and Natanz — in a coordinated effort with Israel. President Donald Trump declared that Iran's nuclear programme had been 'completely and fully obliterated,' although no independent damage assessment has yet been released. Iran's Atomic Energy Organisation confirmed the attacks but said its programme would continue. The UN nuclear watchdog reported no signs of radioactive leakage but confirmed it would continue monitoring. Following the US strikes, Iran launched a retaliatory barrage of 40 missiles targeting Israeli cities, including Haifa and Tel Aviv. Over 80 people were reportedly injured. Israel said it had 'swiftly neutralised' the launchers responsible and began a new wave of strikes on western Iran. Tired of too many ads? go ad free now Trump described the joint offensive as a historic moment. 'We have completed our very successful attack on the three nuclear sites in Iran… All planes are safely on their way home,' he posted online. Israeli Prime Minister Benjamin Netanyahu praised the US President's bold move, calling it a decision that 'will change history.' Meanwhile, Iran's foreign ministry condemned the attacks, warning that the US had 'launched a dangerous war' and reserved the right to respond 'with full force.' The situation has sparked growing international concern, with UN Secretary-General Antonio Guterres calling the strikes a 'dangerous escalation' and warning of 'catastrophic consequences.'

What are the nuclear contamination risks from attacks on Iran?
President Trump announced U.S. military strikes on Iranian nuclear sites, including Fordow, joining earlier Israeli attacks. Experts suggest limited contamination risks from strikes on uranium enrichment facilities, mainly chemical rather than radiological. Gulf states are especially concerned about potential contamination of desalinated water sources if the Bushehr reactor is hit, prompting high alert and emergency plans. Tired of too many ads? Remove Ads WHICH IRANIAN NUCLEAR SITES HAVE BEEN HIT SO FAR? Tired of too many ads? Remove Ads WHAT RISKS DO THESE STRIKES POSE? Tired of too many ads? Remove Ads WHAT ABOUT NUCLEAR REACTORS? WHY ARE GULF STATES ESPECIALLY WORRIED? President Donald Trump said Iran's main nuclear sites had been "obliterated" in military strikes overnight, including on the deeply buried Fordow facility, as the U.S. joined attacks launched by Israel on June have said military strikes on Iran's uranium enrichment facilities pose limited risks of contamination, and the International Atomic Energy Agency (IAEA) said on Sunday no increased off-site radiation levels had been reported following the U.S. U.S. military struck sites at Fordow, Natanz and Isfahan. Trump said Iran's key nuclear enrichment facilities had been "completely and totally obliterated". The attacks follow previously announced Israeli attacks on nuclear sites in Natanz, Isfahan, Arak and Tehran says it aims to stop Iran building a nuclear bomb and the U.S. says Tehran would not be allowed to get such weapons. Iran denies ever seeking nuclear international nuclear watchdog IAEA has previously reported damage to the uranium enrichment plant at Natanz, the nuclear complex at Isfahan that includes the Uranium Conversion Facility and to centrifuge production facilities in Karaj and has also attacked Arak, also known as Khondab. The IAEA said Israeli military strikes hit the Khondab Heavy Water Research Reactor, which was under construction and had not begun operating, and damaged the nearby plant that makes heavy IAEA said it was not operational and contained no nuclear material, so there were no radiological effects. Heavy-water reactors can be used to produce plutonium which, like enriched uranium, can be used to make an atom to Reuters before the U.S. strikes took place, experts said Israel's attacks had posed limited contamination risks so Dolzikova, a senior research fellow at London think-tank RUSI, said attacks on facilities at the front end of the nuclear fuel cycle - the stages where uranium is prepared for use in a reactor - pose primarily chemical, not radiological enrichment facilities, UF6, or uranium hexafluoride, is the concern."When UF6 interacts with water vapour in the air, it produces harmful chemicals," she said. "In low winds, much of the material can be expected to settle in the vicinity of the facility; in high winds, the material will travel farther, but is also likely to disperse more widely. The risk of harmful chemicals being dispersed is lower for underground facilities."Simon Bennett, who leads the civil safety and security unit at the University of Leicester in Britain, said risks to the environment were minimal when subterranean facilities are hit because you are "burying nuclear material in possibly thousands of tonnes of concrete, earth and rock".James Acton, co-director of the Nuclear Policy Program at the Carnegie Endowment for International Peace, said that before uranium goes into a nuclear reactor it is barely radioactive. "The chemical form uranium hexafluoride is toxic ... but it actually doesn't tend to travel large distances and it's barely radioactive," he on enrichment facilities were "unlikely to cause significant off-site consequences", he said, while stating his opposition to Israel's major concern would be a strike on Iran's nuclear reactor at Bushehr on the Gulf of catastrophe rippled through the Gulf on June 19 when the Israeli military said it had struck a site in Bushehr, only to say later that the announcement was a says it wants to avoid any nuclear Wakeford, honorary professor of epidemiology at the University of Manchester, said that while contamination from attacks on enrichment facilities would be "mainly a chemical problem" for the surrounding areas, extensive damage to large power reactors "is a different story".Radioactive elements would be released either through a plume of volatile materials or into the sea, he of the Carnegie Endowment for International Peace said an attack on Bushehr "could cause an absolute radiological catastrophe".For Gulf states, the impact of any strike on Bushehr would be worsened by the potential contamination of Gulf waters, jeopardising a critical source of desalinated potable Gulf Cooperation Council (GCC) is on high alert to monitor for any possible environmental contamination after the attacks, said a source with knowledge of the matter.

Global Leaders React After US Strikes Irans Nuclear Sites
The United States bombed Iran's three nuclear facilities early Sunday which broke out global silence and triggered urgent global leaders to react on the matter of US intervention in the Middle East war. Earlier, US President Donald Trump claimed the attack on the three Nuclear sites in Iran, including Fordow, Natanz, and Esfahan. Trump stated, "There is not another military in the World that could have done this", adding, "Now is the time for peace." World Leaders Reactions Iran Iran strongly condemned the US airstrikes, with Foreign Minister Abbad Araghchi sharing a post on X and saying, "The events this morning are outrageous and will have everlasting consequences. Each and every member of the UN must be alarmed over this extremely dangerous, lawless and criminal behavior." United Nations UN Secretary-General Antonio Guterres expressed grave alarm over the use of force by the United States, warning that further escalation could lead to disastrous consequences. 'There is a growing risk that this conflict could rapidly get out of control – with catastrophic consequences for civilians, the region, and the world,' Guterres said in a statement posted on X. Saudi Arabia Saudi Arabia shared a statement in a post on 'X' and wrote, 'The Kingdom of Saudia Arabia is following with great concern the developments in the sisterly Islamic Republic of Iran, represented by the targeting of Iranian nuclear facilities by the United States of America.' United Kingdom Prime Minister of the United Kingdom Keir Starmer shared a post on X and urged Iran to come back to the negotiating table. 'Iran's nuclear programme is a grave threat to international security. Iran can never be allowed to develop a nuclear weapon and the US has taken action to alleviate that threat,' he said. Israel Israeli Prime Minister Benjamin Netanyahu praised US President Donald Trump for what he described as a 'bold and historic' military operation targeting Iran's three nuclear sites including Fordow, Natanz, and Esfahan. "Congratulations, President Trump. Your bold decision to target Iran's nuclear facilities with the awesome and righteous might of the United States will change history," Netanyahu said.
