Mono-nuclide γ Calibration Source_Atomic High Technology Co., Ltd.

Calibration sources are used for calibration of α/β/γ-ray detector and spectrometer, instrument calibration. They can be prepared with electrochemical method, oxidation film filling, sealing membrane etc. The radionuclide seal in the organic film, then seal in organic glass shell.

Description

Use

Calibration of the energy and efficiency of γ-ray spectrometer.
