IMPROVED FLUORIMETER FOR URANIUM ANALYSIS
A stable fluorimeter, easily operated and serviced, has been developed. Drifts are reduced to a minimum by measuring only the alternating component of the fluorescent light. The exciting ultra-violet radiation is held at a constant level by a special light-stabilizing circuit. The radiation remains stable within plus or minus 1% for power line variations over the range of 200 to 250 v. The initial warm-up is less than 3 minutes compared with 10 to 15 minutes without the light-stabilizing circuit. The sensitivity of the instrument is to better than 10/sup -9/ gram uranium per fused pellet. (auth)
