Iran Releases Nuclear Emergency Survival Guidance Amid Rising US Strike Speculation

Iran has issued an unusual public guide outlining how citizens should respond in the event of a nuclear explosion, including instructions on seeking shelter, limiting exposure to radioactive fallout and preventing contaminated air from entering buildings. The advisory comes amid renewed speculation about a possible US attack on Iran’s underground nuclear-related facilities.

The eight-minute educational video, published by Iran’s state news agency IRNA on October 29, provides recommendations for people to follow during and after a potential nuclear emergency. Citizens are advised to move into basements or protected areas inside sturdy buildings, stay away from windows and switch off air-conditioning and ventilation systems that draw air from outside.

The guidance also recommends remaining sheltered for at least 24 hours following a potential attack, relying on packaged food and bottled water, and avoiding vehicles as places of refuge. Iranian emergency officials warned that radioactive particles could spread through the atmosphere and pose risks well beyond the immediate blast zone.

The advisory has also been reported by Egyptian and Saudi Arabian media outlets.

Advisory Issued During Iran’s Passive Defence Week

The video was released by emergency services in Isfahan province, which is home to the Natanz nuclear facility. Its publication coincided with Iran’s Passive Defence Week, an annual initiative focused on preparedness for security and emergency threats.

The detailed nuclear survival guidance represents a notable shift from Tehran’s public messaging during the Israel-US airstrikes on Iranian nuclear facilities in June 2025. At that time, Iranian officials sought to reassure the public that radiation had not spread beyond the targeted locations.

The latest instructions have attracted attention amid speculation over a potential US strike on Pickaxe Mountain, a deeply buried nuclear-related site near Natanz. US President Donald Trump reportedly discussed the possibility of targeting the mountain on October 16, while ruling out the use of nuclear weapons.

Separately, US commentator Tucker Carlson alleged on November 2 that Israeli Prime Minister Benjamin Netanyahu was pressing Trump to launch a nuclear attack against the site within days. Carlson’s allegation has not been independently verified, and neither US nor Israeli officials have publicly confirmed that a nuclear strike is being considered.

Citizens Told to Shelter Indoors and Shut Off Outside-Air Systems

Iranian emergency guidance identifies four major hazards associated with a nuclear explosion: intense light, blast waves, extreme heat and the release of radioactive materials.

Ebrahim Adelzadeh, deputy director of education and research at the Isfahan Red Crescent Society, advised residents to seek shelter in robust buildings and avoid windows.

According to IRNA, Adelzadeh said that a basement or an interior room away from windows could provide suitable protection, provided it could be reached safely.

Residents were also advised to close doors and windows and turn off air-conditioning units and ventilation systems that bring outside air indoors.

Reports carried by Egyptian outlet Veto indicated that the public was being advised to prepare for at least 24 hours inside a shelter. Saudi outlet News 50 reported additional guidance cautioning people against assuming that conditions would automatically become safe once the initial sheltering period had passed.

What Authorities Recommend if a Blast Occurs Outdoors

The Iranian instructions also address people who may be caught outside during a nuclear explosion.

Authorities advised individuals not to look directly at the intense flash. Those unable to reach a building immediately were instructed to get close to the ground, take cover behind a barrier and protect their heads and faces.

Once the initial blast wave has passed, they should move into the nearest sturdy building as soon as possible.

The guidance also discourages people from staying outdoors to observe or photograph the explosion and warns against using vehicles as shelters. If a building becomes unsafe because of fire or structural damage, individuals should seek another protected location.

Radioactive Fallout May Spread Beyond the Explosion Site

A central concern highlighted in the advisory is the potential movement of radioactive particles through the atmosphere.

Adelzadeh warned that people living far from the initial explosion could still face risks from radioactive contamination. He urged residents to follow official safety announcements and make decisions about their homes and workplaces based on guidance from responsible authorities.

For individuals who may have been exposed to radioactive dust, the recommendations include carefully removing outer clothing, placing it in sealed bags and washing exposed skin and hair with lukewarm water and soap.

Further guidance reported by Saudi News 50 advises using regular shampoo without conditioner, cleaning exposed skin with wet wipes if bathing is unavailable, and consuming packaged food and bottled water to reduce the risk of contamination.

Iran Warns Against Taking Radiation Medicines Without Medical Advice

The video also discusses medicines used in certain radiation emergencies. Abbas Abedi, a spokesperson for Isfahan’s pre-hospital emergency services, cautioned citizens against taking iodine tablets without medical guidance.

He explained that stable iodine may help limit the thyroid’s absorption of radioactive iodine in specific circumstances, but it does not protect against other radioactive substances or radiation from a nuclear explosion.

The advisory also refers to Prussian Blue, a medication used in certain cases of internal contamination involving radioactive caesium-137.

Officials additionally warned that electromagnetic pulses could disrupt electronic devices and communication networks. Battery-powered radios were recommended as a possible means of receiving official updates during communication outages.

Nuclear Strike Speculation Adds to Regional Tensions

The timing of Iran’s public preparedness guidance has drawn attention as speculation grows over the possibility of renewed US military action against Iranian nuclear-related facilities.

The claims surrounding a potential nuclear strike on Pickaxe Mountain remain unconfirmed. Carlson’s allegations about pressure from Netanyahu have not been substantiated by publicly verifiable evidence, and Trump has previously stated that he would not use nuclear weapons against Iran.

Although Iranian authorities have linked the video to Passive Defence Week, the unusually detailed instructions on nuclear emergencies have raised questions about Tehran’s assessment of potential risks amid continuing regional tensions.
