✦ Synopsis

Abstract

The possibility of preparation of mercuriderivatives of fluorescein labelled with ^197^ Hg by irradiation of the respective compounds in a nuclear reactor has been studied. For all investigated compounds, specific activity high enough could be obtained without any significant radiation decomposition. In cases, when the target molecule contained more than one target atom‐bis (hydroxymercurifluoresceinyl) mercury and bis (hydroxymercurifluorescein)‐higher enrichment factor for some products could be obtained. The recommended procedure for preparation of difluoresceinylmercury‐^197^ Hg by this method has been given.
