ABSTRACT:
Method of producing liquid equivalent solid gamma ray calibration standards comprising the steps of adding a first organic solvent to a calibrated aqueous solution of radioactive material, either in the form of a single isotope or mixed isotopes, to form a first solution; mixing the first solution with a polymerizible resin dissolved in a second organic solvent together with a hardening catalyst to form a second solution; and curing the second solution. With isotope standards requiring highly acidic conditions, a stabilizing agent is added to the first solvent to complex with metal and hydrogen ions so as to prevent plate-out.
