Risk maybe small under many situations, But it may not be zero all the time, as numerous anamolies, suspected to caused by EMI have been reported and compiled under ASRS. One of the ways of managing EMI is by controlling electromagnetic emissions. Think of energy of electromagnetic transmissions as a budget. You are only allowed so much. Various techniques, including emissions are employed to stay well within the budget. The EM budget is an important design parameter for all large commercial and defense platforms. There are many mechanisms via which electromagnetic signals can affect aircraft systems.
