適用范圍：This standard applies to equipment consisting of easily transportable autonomous components, and is intended for measurements of rock radioactivity or for measurements concerned with the evaluation and working of deposits. It does not apply to simple instruments for exploration at less than 20 m in depth, nor to vehicle-mounted equipment.The equipment includes:1.1 One or several measuring probes (natural background gamma logging).1.2 A device for the mechanical and electrical connection of the probe with the measuring equipment which may include:— a supporting cable with a winder and pulley measuring the length of cable released (bathymeter) for logging where the probe descends by gravity (vertical or subvertical dips of more than 55 grades [50°] with respect to the horizontal),— a rigid or semi-rigid device to move the probe forward in holes having dips of less. than 55 grades (50°) with respect to the horizontal.1.3 A radiometric indicator, usually a counting ratemeter.1.4 Possibly a recording device, usually of analogue type, the operation of which is proportional to the movement of the probe. Use could also be made of a digital recording device or of a data acquisition system which records probe position in the hole.
