摘要：
A laser-fluorescence system is developed that uses a He-Ne (633 nm) laser for continuous monitoring of I-129 during HNO3 dissolution of irradiated nuclear fuel. Tests at Khlopin Radium Institute indicated that the sensitivity of the I-129 detection (at worst 8.10(-5) g/m(3)) ensures reliable monitoring of this isotope both directly in the working gas during industrial reprocessing of irradiated nuclear fuel and following gas-purification systems at radiochemical plants.
