Abstract
The present invention relates to an improvement in a nuclear measuring gauge for measuring the composition of a hydrogen containing material by counting neutrons which are thermalized by the presence of the hydrogen in the material. The present invention is based upon the recognition that in measuring samples, such as hot asphalt, with such a gauge, the error which is introduced by temperature variations in a sample is a function of not only the temperature of the sample but also its hydrogen content. In accordance with the present invention, this inaccuracy is compensated for by applying to the measurement a correction factor which is a function of both the temperature of the sample and its hydrogen content.
