Use of calculation of 14CO2 volume activity for reconstruction of radiocarbon content changes in atmosphere
Světlík, Ivo ; Fejgl, M. ; Turek, Karel ; Pachnerová Brabcová, Kateřina ; Tomášková, Lenka
Atmospheric 14CO2 provides valuable information for better specification of carbon transport in nature. Radioactive 14C allows calculating some data related to the residence time of carbon in natural sinks as the atmosphere, oceans and biota. The work presents the estimation of 14CO2 content temporal changes in the atmosphere using the radiocarbon calibration curve IntCal09 and data about CO2 concentration during last 50 thousands years.

Carbon-14 is a radionuclide with global occurrence and partly natural origin. This radionuclide is a pure beta emitter with half-live 5730 years. The greatest present artificial source of radiocarbon are effluents from nuclear energy facilities, even though it is minor contribution in comparison with natural production. From all radionuclides released by Nuclear Power Plants (NPP) with Light Water Pressurized Reactor (LWPR) during normal operation, radiocarbon is responsible for major collective effective dose. During 2002 and 2003 samples of biota were collected in NPPs Temelín and Dukovany vicinity (both NPPs have only LWPR) and in reference background localities. Received results are compared and discussed in the point of view of NPPs influences on C-14 amount in the environment of close vicinity
Determination of 14C in point samples of stack air from Nuclear Power Plants
Světlík, Ivo ; Michálek, V. ; Tomášková, Lenka ; Tomeš, Marek ; Brabcová, Kateřina
During normal operation of nuclear power plants (NPP), with pressured light water reactors, is C-14 (relatively) responsible for major contribution of effective dose from all released radionuclides. In this paper is described a new method of C-14 forms determination in short-term (point) sampled stack air from NPPs. Item time series of C-14 activities is reported and compared with results of determinations performed by laboratories of NPP Temelín utilizing monthly cumulated samples
