Description
As a new neutron dosimetry technique, we have proposed to adopt RLA-MS to directly measure the long-lived radionuclides. As a demonstration, we have been attempting to detect trace long-lived radionuclide 26Al produced by DT neutron irradiation. Consequently, we have succeeded to obviously detect 26Al, which has the concentration of 7 ppb, by RLA-MS with the measurement time of 1000 sec. Therefore, we would conclude that RLA-MS have the capability as the new neutron dosimetry technique. (author)
