With global political tensions at unprecedented levels and conflicts raging across multiple regions, Brits are increasingly preparing for worst-case scenarios. In the extremely unlikely event of a nuclear strike on Britain, guidance from the International Commission on Radiological Protection (ICRP) outlines critical actions to take within the first 10 minutes.
Go inside and stay inside
The ICRP describes its 'scientifically backed advice' as potentially lifesaving, explaining that a nuclear blast, whether from a missile or compact portable device, can cause widespread casualties. The organisation states that a 'suitable and proper response' to a nuclear warning or explosion can 'safeguard you and your family's wellbeing and survival'.
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." In the initial 10 minutes following a nuclear strike, it is vital to 'go inside and stay inside'.
The ICRP adds: "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."
Real-life survival example
Providing a real-life 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."
Find shelter before fallout arrives
Another essential measure is to "be inside before the fallout arrives." The ICRP explains: "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."
Based on scientifically-supported radiological advice, the most secure structures for immediate shelter are those featuring brick or concrete walls. The radiological prevention body continues: "Underground parking garages and subways can also provide good shelter."
