Tensions across the globe has caused concern for some UK residents about the possibility of WW3 breaking out, with one expert issuing advice over what to do if a nuclear attack was to occur. The International Commission on Radiological Protection (ICRP) has issued advice on the matter in the grave scenario that a nuclear strike was to happen. According to the organisation, being ‘adequately prepared,’ and ‘responding appropriately’ can significantly help in the protection of your loved ones. It states: “Adequate preparation and appropriate response to a nuclear alert or detonation can protect you and your family’s health and life,” the Mirror US reported. Four answers to questions regarding a nuclear blast have been answered by the body below: READ MORE: Nuke map shows what will happen if Russia or Iran strikes Birmingham in ‘WW3’ The ICRP states that a bright flash which is visible 10km away could indicate a nuclear explosion has occurred. It is said after this, a fireball from the bomb can produce thermal pulses which could last seconds, causing burns and injuries, as well as setting matter on fire such as vegetation and wood several kilometres away from the blast site. The fireball and blast wave can destroy city blocks and damage buildings kilometres away, and flying debris can pose dangers. Initial radiation may harm or kill those outdoors within a few kilometres, according to the organisation. In the first 10 minutes after a nuclear strike, the ICRP recommends: “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.” After the bomb detonates you should have this time to find a safe place to shelter before the fallout begins. Places such as a multi-story building or a basement are thought to be some of the best areas to stay in after a nuclear strike. This is because of the brick and concrete used to built them, which means finding a place with an underground parking lot or if you are in London, the underground, could offer protection. Removing your outer layers of your clothing and any footwear which could be contaminated is advised, as well as thoroughly cleaning any exposed skin or hair. If you have pets with you which could have been affected by the radiation, it is suggested to brush them in a separate room and keep them away from people, as well as washing them if you have the means to do so. The ICRP recommends that you should tune into any available media stations within 24 hours of the attack, which is most likely to be an AM or FM radio station on a battery powered device. Keeping the device on for updates is key with the organisation also advising: “Stay inside unless instructed otherwise. “Remain in the most protective location (basement or centre of a large building) for the first 12 – 24 hours unless threatened by an immediate hazard (e.g., fire, gas leak, building collapse, or serious injury) or informed by authorities that it is safe to leave.” It is advised to only leave your shelter when the hazardous fallout zones have been identified and evacuation routes have been clearly mapped out. Those classed as essential workers are likely to be able to leave shelters to carry out vital work around the country, the publication said.
