Claim:
1. A method for calibrating a nuclear gauge of the having a source, the method comprising: 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; wherein an operator places the gauge on one or more specified blocks to adjust the source within each of the one or more specified blocks to one or more specified positions to initiate a count; determining that the source is at each of the one or more specified positions before each count begins; selecting the proper counting times before each count begins by the program on the nuclear gauge based on each of the one or more specified positions of the source to obtain calibration information; obtaining counts at each of the one or more specified positions; storing the counts within the computing system of the nuclear gauge; and calculating, by the nuclear gauge, for each of the one or more specified positions, calibration coefficients.
