Abstract
Fossil CO2 emission inventory from waste incineration plants needs to be determined for the purpose of emission trading in the future. A fundamental method for this is to measure the 14C content of the exhaust gas using accelerator mass spectrometry (AMS) and deduce fossil/biofraction from it. Conventionally, the CO2 in the sampled exhaust gas has been graphitized for the AMS measurement. In this work we have tested a method where the sample is fed to the AMS system in gas form, without the extra graphitizing step. The sample gas storage and feeding system of Helsinki Accelerator Laboratory is represented along with the results obtained in the test with flue gas samples from test combustion facility. The results show that the analysis of biofraction of combusted fuels is possible in feasible, reproducible and accurate ISO13833 standard compliant way with the tested method.
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.
