Abstract
The factors are studied strongly influencing the laser-excited fluores cence of molecular iodine-127 present in the atmospheric air. The para meters optimal for the sensitivity of iodine-127 detection are determi ned: the temperature of iodine vapor, the frequency of exciting radiat ion, and the pressure of the analyzed gas mixture. Under the optimal p arameters, the fluorescence intensity increases 20 - 25 times, providi ng a reliable control of iodine-127 in the atmosphere at the level of permissible concentrations for living zones.
