Yesterday the South Iowa Highway patrol banned the use of radar guns due to concerns over long term exposure to the radiation emitted by the guns. Further studies will be performed to find links between cancer and the use of the guns.

Highway Patrol spokesman Adam Smith said “The feeling here is to err on the side of caution until more is known about the issue. The whole situation is still under review.”

The ban affects 70 guns currently in service but the Highway Patrol. The Highway Patrol will still be using radar units attached to their cars to continue monitoring speeds.
