Abstract Measurements of Cs<sup>137</sup> content were made in all persons referred for measurement of their body radioactivity, beginning in Jan. 1958. The largest group of these people comprised women who had worked in the radium-luminizing industry. Measurements were made on 203 of the luminizers, 182 females and 21 males. Measurements were made for Cs<sup>137</sup>, K<sup>40</sup>, and radium by detecting their gamma energies and comparing the spectrum for each subject with that from calibration sources. Finally, from these measurements, it was determined that the mean annual dose received by those measured, from Cs<sup>137</sup> in the body, was less than 2% of that from natural sources, which is approximately lOO mrem/ year.
