Tunisia's coastline stretches for over 1 300 kilometres. It's a major source of income for the people who live along the coast - that's around 80 percent of the country's population. But like many coastal countries around the world, this North African country is trying to cope with the pollution coming from industrial and domestic waste that is affecting the shorelines. The country's National Center of Nuclear Sciences and Technologies (CNSTN) takes part in a regional IAEA project that supports the use of nuclear and isotopic techniques to manage marine pollution.
