You're listening to the BBC World Service now, Angela Robson

travels to Lois, PDR, to investigate the legacy of the intensive

bombing campaign during the Vietnam War. The country is still covered

with unexploded bombs or UXOs. Angela investigates

the now lucrative and dangerous business of collecting UXOs

in bomb hunters.

Overlau, no. It is estimated that there was one bombing mission

every eight minutes, 24 hours from 1964 to 1973.

So imagine, playing a load of bombs, coming in and just dropping

bombs over and suspecting people that would have been really bad.

One of these has a killing radius of definitely 15 metres

but up to 30 metres if you're unlucky. The ball bearings just get flown out

and just rip through flesh. There was one accident in January where

some children were digging for crabs and they saw one of these in the ground.

They picked it up and when they realised what it was they dropped it and it killed four children and injured five others.

That's just from one. There's 260 million of these dropped

and 80 million could still be left after the war.

Unexploded illness is very much part of life. It's been here for more than 30 years now.

It's a resource which people use. They'll use it for stilts for their houses.
