: Silent Decay: What Happens When a Murder Weapon Emits Radiation

When former Russian security officer Alexander Litvinenko fell mysteriously ill in London, doctors couldn't explain what was happening to him — until forensic testing revealed polonium-210, an almost unheard-of poison, inside his body. This episode traces how that discovery exposed a radiological trail across London and forced investigators to reconstruct a covert assassination method built specifically to evade detection. We look at the tradecraft behind the poisoning, why conventional toxicology initially failed to catch it, and what the case reveals about state-sponsored killing methods. It's a rare look at how espionage and forensic science collided in one of the most notorious poisonings in modern intelligence history.
