Sewer sensors to sniff out bomb ingredients
A new project in Sweden is using a network of hi-tech sensors in the sewer system in the fight against terrorism.
The sensors can detect minute traces of the bomb ingredients, recording their concentration, the time they were found and their location.
This information is then sent out to police.
Hans Oennerud has been coordinating the EU-funded project known as Emphasis.
