VIDEO: In Lawrence County emergency officials and volunteers took part in an exercise to test their response should a nuclear accident take place in Pennsylvania. It is a scenario where they hope for the best but prepare for the worst. Local Fire Departments and the Lawrence County Department of Public Safety took part in a preparedness exercise at Mohawk High School. The mock scenario they must respond to is a general accident at the Shipping Port Nuclear Power Plant in Beaver County. Those who were exposed would pass through this detector. "Every two years we are evaluated by FEMA to make sure we can receive people being evacuated from Beaver County. They will come to this location, walk through a portal monitor to make sure they have not received any contamination from the power plant," said Chad Strobel, Public Safety Director for Lawrence County.
