In this essentially empirical study a comparative analysis of the age of references in scientific papers in three subject fields is performed. Comparisons are made: 1. among national and leading journals in the same scientific field, 2. for a number of high quality journals in physics and chemistry, and 3. between several groups of authors (according to the countries of origin), contributing to the same journals in chemistry. Variations found in the journals citing half-life values suggest that, if properly interpreted, the citing half-life might reflect the journal's quality and might serve as a certain indicator for the citing practices of specific groups of authors.
