Abstract
A sensitive and specific analytical method for beryllium in air, swipe, biological, and packing material samples was developed. A single-beam atomic absorption spectrophotometer and high-temperature nitrous oxide-acetylene flame is used. The chemical technique for sensitivity enhancement and decontamination from radionuclides is described. Maximum time expenditure for an analysis is less than 30 minutes. Multiple samples may be run in the same time period. Sensitivity of the method is less than 0.04 parts per million of beryllium with a repeatability of approximately 2% of the amount present. Decontamination factors for uranium and transuranium elements were greater than 5000.
