摘要
Photon emission intensities of Pb-210 have been determined using sources prepared from a standard solution, whose activity was measured by liquid scintillation counting. The absolute gamma-ray and X-ray emission intensity was measured by conventional gamma-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.
