ABSTRACT:
The invention concerns a novel method adapted to experimental conditions, for determining the function defining the actual detecting sensitivity of a solid-state detector of nuclear traces and which represents the detecting performances for each type of nucleus emitting energy alpha particles Ei, located in each position inside a sample to be analyzed, and hence precision dosimetry of the radioactive nuclei in a sample using nuclear trace solid-state detectors. The method provides an improvement of the quality of sample analyses, a significant reduction of analysis costs and an important widening of the scope of application of this type of detectors. Thus, the method will bring about the development of a new generation of detectors having a better price-quality ratio which can be found in the field of radioactive nuclei analyses in different types of samples.
