OSLO, June 4 (Xinhua) -- Never before has Norway experienced stronger ultraviolet (UV) radiation during May as this year, online newspaper Nettavisen reported Monday.
Strong UV radiation was also measured during the first two days in June and was caused by a lot of sunshine, the report said.
"Small children have thin skin and hence a big need to protect skin properly," Hallvard Reigstad, attending physician at the Children's Department at Haukeland University Hospital, told public broadcaster NRK.
The doctor added that the situation is perceived as extreme and that the children who are exposed to strong sunlight can have long-term sun damage.
"Much indicates that both total exposure to heavy sunlight and repeated sun damages lead to skin cancer," he said.
