1. An electrical resistivity tomography (ERT) survey system comprising:
a current supply;
a master controller operatively connected to the current supply;
a pair of injection electrodes operatively connected to the master controller;
a pair of measurement electrodes operatively connected to the master controller;
each injection electrode of the pair of injection electrodes forming a radiating injector body which provides a uniform electrical field density;
each measurement electrode of the pair of measurement electrodes forming a radiating measurement body which receives the uniform electrical field density; and,
wherein the uniform electrical field density is produced during an ERT survey;
wherein each radiating injector body is only hemispherical.
