Uptake of short half-life radionuclides, 28{sup left}Mg, 43{sup left}K and 47{sup left}Ca, in carrot studied by the multitracer technique: Feasibility of utilization of the radionuclides in environmental research

摘要

We investigated successfully the uptake of the radionuclides with short half-lives, such as 24{sup left}Na, 28{sup left}Mg, 43{sup left}K and 47{sup left}Ca, and the effect of stable Ca on their uptake in carrot (Daucas carota cv. U.S. harumakigosun) by the multitracer technique. These radionuclides were produced by a fragmentation reaction of Ti in a 135 MeVucleon 12{sup left}C beam accelerated by the RIKEN Ring Cyclotron. This study shows that these radionuclides in a multitracer can be utilized in environmental research.
