| Use: | Utilized with the cone penetrometer (see 3.3.1) to measure radionuclides. |
Description:
A piezoelectric element converts digital-coded data at the tip of the cone penetrometer probe to an acoustic signal that is transmitted along the drill rods to a microphone mounted on the drill rig. The microphone converts the signal to data that is transmitted to a personal computer, which presents both analog and digital information.
