Nuclear gauges and methods of configuration and calibration of nuclear gauges
First Claim
1. A nuclear gauge comprising:
- a gauge housing including a vertical cavity and a base;
a radiation detector located within the gauge housing and adjacent to the base of the gauge housing;
a vertically movable source rod extending into the vertical cavity of the gauge housing;
a radiation source carried by a distal end of the source rod;
a computing system located within the gauge housing;
a first user interface mounted on the gauge housing and in communication with the computing system, wherein the first user interface comprises a keypad;
a handle coupled to the source rod;
a support member connected to the gauge housing, the support member defining at least one routing compartment;
electrical wiring extending along the routing compartment; and
a second user interface mounted on the support member, the second user interface comprising a switch for initiating a gauge measurement, wherein the switch is in electrical communication with the computing system by way of the electrical wiring.

Abstract
A method for calibrating a nuclear gauge of the having a source includes providing a nuclear gauge comprising a radiation source, the radiation source being coupled with a computing system with a machine readable program stored thereon containing a calibration routine. An operator places the gauge on one or more specified blocks to adjust the source within each block to one or more specified positions to initiate a count. The method includes determining that the source is at each position before each count begins, adjusting the counting times before each count begins by the program on the nuclear gauge based on each position of the source to obtain calibration information, obtaining counts at each position, storing the counts within the computing system of the nuclear gauge, and calculating for each position calibration coefficients.
