Non-ionizing radiation can also cause other adverse health effects. A famous Norwegian case in the early 90s related to navy personnel on board an attack vessel, where 17 of the 85 children of soldiers who had served on the vessel, had birth defects. A disproportionate number of the employees on the electronics workshop of its home base also has children with similar birth defects

The negative effects are widely believed to have been caused by a 750W radar jammer, which frequently radiated the ship deck. There hasn't been established a clear cause-and-effect link.
