WORKING SUBSTANCE FOR THERMO-EXOELECTRONIC DOSIMETRY Russian patent published in 2008 - IPC G01T1/20 G01T3/06 

FIELD: physics; measurements.

SUBSTANCE: invention pertains to thermo-electronic dosimetry of electron beams, and can be used for controlling a radiation environment in places for testing and operating pulsed electron beams and in electron beam technology. In the working substance for thermo-exoelectronic dosimetry of an electron radiation, the oxide base used is an orthosilicate of gadolinium with additives of ceric oxide, with the following ratios of components, mol.%: Gd₂SiO₅ 97.0-99.9; Ce₂O₃ 0.1-3.0. The technical outcome is the lowering of the temperature of the base working TEE peak to 48°C with fluence of electrons of 10¹⁰-10¹³ cm^-2 and to 75-79°C with fluence of electrons of 10¹³-10¹⁵ cm^-2, and increased speed of recording dosimetry information when reading from the working substance for thermo-exoelectronic dosimetry and increased speed of bringing the working substance into a state where it is ready for use.

EFFECT: increased speed of recording dosimetry information.
