Even behind thick concrete walls we can feel the blast as a dull thud in the chest. <\/p>\n<p>By military standards the explosion is small, about the size of a hand grenade, but it is powerful enough to create the phenomenon that we have come to see. <\/p>\n<p>Trevor&#8217;s team at Cranfield University&#8217;s explosive test centre on Salisbury Plain have installed high speed cameras around the range. <\/p>\n<p>In super slow motion, they clearly show the primary blast wave, a hemispheric wall of energy moving outwards from the seat of the explosion at the speed of sound, compressing the air in front to create a pulse of overpressure.<\/p>\n<p>It is this pressure wave that scientists now believe is damaging soldiers&#8217; brains, even when they fire their own weapons in training.<\/p>\n<p>Professor Ben Dunkley, who has studied blast exposure in Canadian soldiers and veterans, explained: &quot;That shock wave is hitting the body and then that energy is being transmitted into the brain and it&#8217;s just like being shaken around.<\/p>\n<p>&quot;It can cause shearing damage, injure the cells and over time they can degenerate and die off.&quot; <\/p>\n<p>Now, for the first time, Nato has issued guidance to member states on how much blast overpressure troops should be exposed to in training.<\/p>\n<p>For the UK, where there are currently no restrictions at all and where the government treats soldiers&#8217; brain health as an area for research rather than action, the report represents a significant step. <\/p>\n<p>The Nato guidance is for armies to limit overpressure in training to four pounds per square inch (Psi) for a single exposure and a cumulative daily total of 32 Psi. The alliance says it may revise these guidelines as the science evolves. <\/p>\n<p>\u2022 Subscribe to ITV News on YouTube: http:\/\/bit.ly\/2lOHmNj<br \/>\n\u2022 Get breaking news and more stories at http:\/\/www.itv.com\/news<\/p>\n<p>Follow ITV News on TikTok https:\/\/www.tiktok.com\/@itvnews?lang=en<br \/>\nFollow ITV News on Instagram: https:\/\/www.instagram.com\/itvnews\/<br \/>\nFollow ITV News on Facebook: https:\/\/www.facebook.com\/itvnews\/<br \/>\nFollow ITV News on X: https:\/\/twitter.com\/itvnews<\/p>\n","protected":false},"excerpt":{"rendered":"<p>From a red metal box, Trevor Lawrence picks out a lump of what looks like plasticine, the shape and size of a tennis ball.
