P4_5 The Relativistic Ionisation Speed Limit

Magdalena Szczykulska, Jason John Watson, Lilian Garratt-Smithson, Alistair William Muir


The paper explores a possible speed limit to be enforced on relativistic vehicles so as to not expose pedestrians to ionising electromagnetic radiation; a result of Doppler shifted light from the vehicle’s headlights. A maximum speed limit of 2.89 × 108 ms-1, 0.96 times the speed of light, was established.
