Abstract

Abstract: Photon emission intensities of 210 Pb have been determined using sources prepared from a standard solution, whose activity was measured by liquid scintillation counting. The absolute γ-ray and X-ray emission intensity was measured by conventional γ-ray spectrometry. Complementary measurements of the L X-ray spectrum were performed using a cryogenic detector, characterized by very high energy resolution and constant detection efficiency. As a result, precise emission intensities of the individual X-ray lines were obtained taking into account the presence of satellite lines. Highlights: Activity per unit mass of a 210 Pb solution determined by liquid scintillation counting. Absolute emission intensity of the 46.54 keV transition measured by γ-ray spectrometry. Ultra-high energy resolution measurements using a metallic magnetic calorimeter. Absolute X-ray emission intensities are derived.
