Abstract

A

The theoretical radiometric anomalies caused either by a pinpoint source or by a larger one, which could be detected 75 metres above the source by a mobile detector with a very low velocity and time constant, were treated by an analog simulator which gave the curves transformed by the effect of velocity and time constant. The characteristics of these curves are discussed.

An actual airborne survey above a radioactive anomaly of small surface yielded results which are analyzed and compared with the previous theoretical data. The degree of agreement between theoretical and experimental results seems satisfactory.

This study shows that the deformation of curves by velocity and time constant in most actual surveys is small enough when the product of velocity and time constant is less than 75 m for a flying altitude of 75 m.
