Determination of I-129 in biomonitors collected in the vicinity of a nuclear power plant by neutron activation analysis
Original language description
Neutron activation analysis (NAA) was used to determine I-129 and the I-129/I-127 ratio in bovine thyroid, moss, and river sediment samples collected in the vicinity of the Temelin nuclear power plant (NPP) in south Bohemia. The NAA procedures comprisedpre-irradiation separation of I-129 by combustion of the samples in the stream of oxygen at 1,000 A degrees C and trapping the liberated iodine in a LiOH/(NH4)(2)SO3 solution. Post-irradiation separation of I-130 produced by the reaction I-129(n,gamma)I-130 was carried out by extraction of elementary iodine with chloroform followed by precipitation of PdI2. Nondestructive, epithermal NAA was used to determine I-127 employing the I-127(n,gamma)I-128 reaction. The results showed that mean values of I-129and the I-129/I-127 ratio in the bovine thyroids varied from 22 to 61 mBq kg(-1) (dry mass) and 2.8 x 10(-9) to 5.4 x 10(-9), respectively. These values are close to the lower end of results reported from various regions non-polluted with
