摘要：
An improved method has been developed that allows the determination of I-129 in conifers around nuclear facilities using neutron activation analysis. Pine and cedar needle samples were collected from the surroundings of Atucha and Embalse Nuclear Power Plants, Centro Atomico Ezeiza, as well as from background areas in Argentina. I-131 was used as tracer. A chemical recovery of 98-100% was obtained for pre-irradiation distillations and total recovery was 70-85%. The minimal detectable amount (MDA) was 0.01 mBq/g of sample, depending on the total recovery, natural iodine concentration, irradiation time and neutron nux. The results presented in this paper are the first published from Argentina.
