Gareth Collett on a career in bomb disposal

Gareth Collett on a career in bomb disposal

Author: BBC Radio 4 October 21, 2025 Duration: 28:29

Movies might have us believe that bomb disposal comes down to cutting the right wire. In fact, explosive devices are complex and varied - and learning how to dispose of them safely involves intense training, as well as the ability to stay calm under pressure.

This was the world of Dr Gareth Collett, a retired British Army Brigadier General and engineer, specialising in bomb disposal; whose 32-year military career took him around the world, including heading up major ordnance clearance projects in Iraq and Afghanistan. After retiring from the army, Gareth became a university lecturer – but following his diagnosis with bladder cancer, started researching a possible link between bomb disposal veterans and higher rates of urological cancers.

In conversation with Professor Jim Al-Khalili, Gareth discusses this ongoing research, dealing with PTSD - and why he just can't watch Oscar-winning movie The Hurt Locker...

Presented by Jim Al-Khalili Produced by Lucy Taylor for BBC Studios


Hosted by physicist and author Professor Jim Al-Khalili, The Life Scientific offers a rare and intimate glimpse into the minds shaping our world. Each conversation moves beyond the standard lecture or interview, weaving together personal history with groundbreaking ideas. You’ll hear how childhood curiosity, unexpected setbacks, and moments of sheer luck have steered the careers of some of today's most influential researchers. This BBC Radio 4 podcast treats science not as a remote collection of facts, but as a deeply human endeavor driven by passion, perseverance, and sometimes, serendipity. The discussions delve into the real process of discovery-the late-night frustrations, the collaborative breakthroughs, and the ethical questions that arise from new knowledge. While exploring everything from the smallest particles to the vastness of the cosmos, the core of each episode remains the individual behind the science. Listeners come to understand not just what these scientists know, but who they are and what continues to drive them forward. It’s a series that connects the personal to the universal, making complex fields accessible and profoundly relevant. By focusing on the life as much as the science, this podcast reveals how our future is being built, one question at a time, in labs, field stations, and offices around the globe.
