In a statement to The Associated Press, the Lithuanian government said the pills, which help reduce radiation buildup in the thyroid gland, will be delivered by the manufacturer in a month.
They will then be handed out for free to citizens in case of a radiation leak at the Astravets nuclear power plant, which Belarus plans to open later this year.
The Baltic country of 2.8 million people is opposed to the nuclear power plant south of Lithuania, and has forbidden purchase of energy from Belarus.
In 2009, Lithuania closed its sole nuclear power plant.
