Аннотация:
A photometer with a sensitivity of about 10<sup>-10</sup> lumens is described. This instrument has been incorporated in a fluorimeter for the determination of very small quantities of uranium: this fluorimeter is also described, and test results are quoted which show that an average instrument has a sensitivity permitting about 5 × 10<sup>-10</sup> grams of uranium to be measured.
