Presentation Transcript

  1. Radio Frequency (RF) Hazards

  2. Principles Electrical Equipment Radio Frequency (RF) Electro-Explosive Device (EED) Ammunition functions unintentionally

  3. Principles

  4. Principles

  5. Exposure Levels

  6. Safe Separation Distances Circular ends = a right cylinder Oval (or otherwise not circular) ends = NOT a right cylinder

  7. Safe Separation Distances

  8. Safe Separation Distances • Emergency Situations: • Radius of 10m: No RF transmission • Radius of 50m: No vehicle-borne sets on transmit (eg emergency services) • Emergency instructions issued to crews of vehicles transporting EED

  9. Calculation of Safe Separation Distances • Calculating transmitter field strength: • Type of aerial (directional or omni-directional) • Mean power supplied to antenna • The frequency or frequency band • The antenna gain • And if the transmitter has a pulse waveform: • The pulse repetition frequency (pulses per second) • The pulse width in seconds

  10. Calculation of Safe Separation Distances
