SELF-SCINTILLATING SHEET MATERIAL FOR RADIOACTIVE SPECIES ANALYSIS

摘要

A sheet article includes a porous matrix or membrane comprising separators for radioactive species and scintillators which emit light in response to radioactive emissions from the species. The sheet article is useful in a method to detect and quantify the radioactive species. The method comprises the steps of contacting a fluid comprising a radioactive species through or by a porous matrix or membrane or exposing such a membrane containing the scintillator to the fluid, allowing the radioactive species in the fluid to be passively sorbed by the membrane comprising: 1) separators which sorb or react with said radioactive species, and 2) scintillators which emit light in response to said radioactive emissions, and detecting and quantifying the emitted light.
