With a total amount of plutonium between 0.4 and 0.8 mg the standard deviation of a single result is less than 1 per cent. For samples of diverse origin interferences are eliminated, usually by simple chemical pre-treatment or by separation procedures, to give a clean solution for analysis. On the other hand, for large numbers of samples with a comparable matrix, it is worthwhile to devise calibration standards so that such samples can be analyzed directly.

We have developed an analytical method for detection of 239Pu in aqueous samples at concentrations as low as 10−1° M. This nuclear counting technique utilizes the uranium L X-rays, which follow the alpha decay of plutonium. Because L X-rays are specific for the element and not for the individual isotopes, the isotopic composition of the plutonium sample must be known. The counting efficiency in the 11--23 keV range is determined from a plutonium standard, and the concentration of the sample is then calculated from the L X-ray count and the isotopic composition. The total L X-ray count is corrected for possible contributions from other radionuclides present as impurities by measuring the low-energy gamma spectrum for each contaminant to establish specific photon/X-ray ratios. The ratios are important when 241Pu and 242Pu are measured, because the respective decay chain members produce non-U L X-rays. This new method can replace the use of labor-intensive radiochemical separation techniques and elaborate activation methods for analysis of 239Pu in aqueous samples. It is also applicable for assaying plutonium in liquid wastes that pose possible hazards to the environment.
