Abstract:	A neutron activation determination of the content of¹²⁹I in the cooling water of nuclear power reactors is described.¹²⁹I is coprecipitated as PbI₂. After neutron irradiation the gamma-spectrum of PbI₂ is measured. The detection limit for¹²⁹I is 2.9 mBq/dm³. The applicability of X-ray spectrometry for¹²⁹I determination is also evaluated. The proposed methods are applied for determination of the¹²⁹I content of the cooling water of WWR-440 type reactors at the nuclear power station Kozloduy, Bulgaria
