Abstract: ¹³¹I was measured by gamma spectrometer for water in Pear River in Guangzhou. 15 L water was vaporized in condition of pH=7 and 0.5 mg/L iodine. The recovery rate of ¹³¹I is 95%and the lower detection limit is 0.004 Bq/L. The concentration of ¹³¹Iis 0.03-0.20 Bq/L during 2011-2013.

Key words: Gamma spectrometer monitoring, ¹³¹I, Vaporized, Pear River
