Britons have been issued crucial lifesaving guidance on what to do within the first 10 minutes of a nuclear strike on the country. The advice, published by the International Commission on Radiological Protection (ICRP), tells people to 'go inside and stay inside' immediately after a nuclear detonation.
The guidance comes as global uncertainty persists and international political tensions reach unprecedented levels, with Brits increasingly taking precautionary measures for worst-case scenarios.
Scientifically supported advice
The ICRP states that a nuclear explosion, whether from a missile or compact portable weapon, has the capability to cause widespread casualties. The body says an 'adequate and appropriate response' to a nuclear warning or explosion carries the 'ability to protect you and your family's health and life'.
The guidance explicitly states: "The best way to protect you and your family before, during, and after a nuclear blast is getting inside the centre of a building or basement."
Key actions in the first 10 minutes
Official guidance states that within the first 10 minutes following a nuclear attack, it is essential to 'go inside and stay inside'. The ICRP explains: "The best thing you can do after a nuclear detonation is go inside. Get inside the center of a building or basement to put as much material between you and the radioactive material outside."
Another critical action to take within the first 10 minutes is to: "Be inside before the fallout arrives." The ICRP advises: "After a detonation, you will have 10 minutes or more to find an adequate shelter before fallout arrives. If a multi-story building or a basement can be safely reached within a few minutes of the explosion, go there immediately."
Real-world example and best shelters
Offering a remarkable yet sobering real-world example, the ICRP shares: "On August 6, 1945, Mr Eizo Nomura was in the basement of a building in Hiroshima, about 170 meters from ground zero. He survived the atomic bombing and died in 1982 at the age of 84. Most people within a few hundred metres of a nuclear detonation are not likely to survive, especially if unprepared."
According to the scientifically-endorsed radiological guidance, structures with brick or concrete walls offer the greatest protection immediately following a nuclear strike. The radiological prevention organisation further notes: "Underground parking garages and subways can also provide good shelter."
