can triggered Spark gap be effected by electromagnetic radiations?

Question

some times spark plugs used as switching device in some circuits.These circuits are used in electromagnetic radiation envirenments,some misfire problems found in spark plug was it due yo this field of electromagnetic radiations.

Answer 1

Electromagnetic interference can cause a spark gap to prefire if it's intense enough, but it's unlikely to cause a misfire. Misfiring generally means that the gap has increased due to erosion. Polish and regap the electrodes. Clean the insulator while you're at it.
