Information campaigns and warnings are not enough to protect students from overexposure to UV rays that can cause skin cancer and other problems, the Swedish Radiation Safety Authority warns.
The authority will therefore developed proposals over the next three years on how to create schoolyards and playgrounds with low UV exposure.
"We want the children to be out as much as possible and when they are there, neither they nor adults should have to think about how the children should be protected from UV radiation in summer, because the environment is already adapted," Hélène Asp, who heads up the authority' department of radiation on, said to newspaper Dagens Nyheter.
Skin cancer is the fastest growing type of cancer in Sweden and is the second most common kind of cancer in both men and women.
Asp said the agency wants all school grounds for pre-school children and students up to the age of 12 to be UV proof.
To do that, the agency will look at planting trees with large canopies on school grounds as well as creating shaded walkways with covered arbors or tents.
