METHOD OF DETECTING RADIOACTIVE SUBSTANCE

摘要

METHOD OF DETECTING RADIOACTIVE SUBSTANCE A method of detecting radioactive substance in a liquid sample in which the liquid sample is supplied continuously or intermittently to a radiation-measuring instrument containing a stimulable phosphor. The said measuring instrument is kept in contact with the liquid sample for a given period of time to cause the instrument to absorb at least a portion of radiation energy emitted by the radioactive substance in said liquid sample. The measuring instrument is irradiated with an electromagnetic wave to release the radiation energy stored in the instrument as stimulated emission. The emission is photoelectrically detected to measure radioactivity of said liquid sample sequentially. The method is particularly useful when employed in conjunction with liquid chromatography.
