The Iowa governor just confirmed that the scout camp DID have a weather radio.
According to this quote from a CNN article, I'm not sure they were using the weather radio. Or it is possible that they received the warning via radio but didn't act until they had a visual of the tornado. In either case, there probably isn't much more they could have done if the structures in which they took shelter were destroyed.
"We were sitting there watching lightning ... and we saw it [the tornado] come around the end of a bluff toward the entrance of the camp," Logsdon said. "So we flipped on the siren and the youth staff members ran to the assigned shelters."
The adult leader ordered everyone to get under the tables.
"All of a sudden, two seconds later, the tornado was on top of us," Logsdon said. "I know it picked up our adult leader's car and threw it 50 yards, easy."
