Low Frequency Electromagnetic Interferences Impact on Transport Security Systems Used in Wide Transport Areas

The article presents the impact of electromagnetic interferences of low frequency range, on transport security systems used in wide transport areas. Intended and unintended (stationary and mobile), electromagnetic interferences, impacting on items and components constituting transport system at wide area (seaport, railway, etc.), cause changes of its vulnerability, resistance and durability. Diagnostics of interferences sources (amplitude, frequency range, radiation characteristics, etc.), appearing within transport environment, and usage of appropriate technical solutions of systems (i.e. shielding, reliability structures), allows for safe implementation of safety surveillance of human beings, properties and communication means.
