contact with the sensor. There are no restrictions on the
distance between the sensor and the surface of the ore, no
restrictions on particle size or moisture content of the ore
(Figure 8).
MRA Safety
Interlocks are fitted to all high voltage areas to ensure
personnel safety, and all accessible areas adjacent to the
conveyor belt have radiofrequency field strength well below
public exposure limits as defined in (Australian Radiation
Protection and Nuclear Safety Agency (arpansa), 2021) The
sensor does not use ionising radiation.
No additional site-specific safety controls were required
beyond those which are embedded in the MRA.
