Measurement of absolute K X-ray emission intensities in the decay of 103mRh

J Riffaud et al. Appl Radiat Isot. 2018 Apr.

Abstract

A new experiment was designed to measure the photon emission intensities in the decay of 103mRh. The rhodium samples were activated in the ISIS experimental nuclear reactor at CEA Saclay. The procedure includes an absolute activity measurement by liquid scintillation counting using the Triple-to-Double Coincidence Ratio method, followed by X-ray spectrometry using a high-purity germanium detector to determine the photon emission intensities. The new result (IX = 0.0825 (17)) is derived with a significant reduction of the uncertainty.

Keywords: (103m)Rh; Photon emission intensity; Reactor dosimetry; TDCR method; X-ray spectrometry.
