BS EN 50475 is a European standard on the measurement of human exposure to electromagnetic fields (EMF) from broadcasting service transmitters that discusses the basic standard for the calculation and the measurement of human exposure to electromagnetic fields from broadcasting service transmitters in the HF bands (3 MHz - 30 MHz) to ensure protection against EMF exposure.
BS EN 50475 applies to short wave broadcast transmitters and installations operating in the frequency range 3 MHz to 30 MHz.
The objective of BS EN 50475 is to specify, for such a frequency band, basic information allowing the definition of a method for assessment of compliance related to human exposure to radio frequency electromagnetic fields.
BS EN 50475 on the measurement of human exposure to EMF from broadcasting service transmitters is useful for:
Shortwave transmitters are used to broadcast radio programmes or data streams over regional, national, or even intercontinental distances to an unlimited number of receivers.
BS EN 50475 provides you with guidance on the applicability of compliance assessment methods, SAR measurement and calculation (local and average SAR), current density (3 MHz – 10 MHz), measurement of the electric and magnetic field, calculation of electric and magnetic field, contact currents measurement and calculation, induced current calculation and measurement (10 MHz – 30 MHz), etc.
The assessment methods provided by BS EN 50475 assist you in improving the performance and quality of the shortwave broadcast transmitters, enhancing safety, improving human working conditions, and counteracting adverse effects on human health and performance.
With obedience and compliance to BS EN 50475, you can enhance shortwave broadcast transmitters’ effectiveness and efficacy and manufacture a standardized high-quality product.EN 50475:2008
