Measurement of the 211At activity via alpha-particles counting with a liquid scintillation spectrometer.
Alpha-particle emitters have garnered considerable interest as therapeutic radiopharmaceuticals, with 211At emerging as a viable candidate. In this study, the activity concentration of an 211At solution was determined via alpha-particle counting with a liquid scintillation spectrometer. Alpha-particles, in the region of interest set for pulse-height spectral measurement, were counted, and the counts were corrected for alpha-particle counting efficiency determined using 241Am standard source. The uncertainty in the alpha-particle counting efficiency was the largest contributor to the overall uncertainty. This result suggests that the combined uncertainty can be reduced by improving the method for evaluating alpha-particle counting efficiency.
期刊介绍：
Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment.
The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria.
Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
