Description

Eleven transportable, portable hand counter or face scanner calibration blocks were constructed from predetermined mixtures of sand, uranium ore, and concrete. These blocks, 42 in. dia. and 17 in. deep, approximate an infinite source, in both the vertical and horizontal directions, for the gamma rays of interest. The grades assigned to these blocks, for the purpose of calibrating portable gross gamma detectors, were determined by a procedure based on a standard least-squares technique for limiting sampling errors
