Brussels: The entire population of Belgium is to be issued with a ration of iodine tablets, months after warnings about the threat of Islamic State building a dirty bomb.

Iodine pills, which help reduce radiation build-up in the thyroid gland, had previously only been issued to people living within 20km (14 miles) of the Tihange and Doel nuclear plants.

Maggie De Block, the health minister, said that would be extended to 100km, covering the whole country of 11 million people, following advice from an expert council.

The pills will be sent to pharmacies, and the public would be ordered to collect their ration in the event of a meltdown.
