Some basic considerations were made on the special characteristics of measurements for radiation protection activities. The authors emphasized that the measurement techniques should be thoroughly re-examined, not from the standpoint of pure radiation dosimetry, but from the standpoint of routine radiation protection practice. It is one of the most important characteristics that complicated uncertain factors are inevitably concerned with the measured value in the field of radiological protection. The authors indicated some error-introducing factors in several measurement techniques and emphasized that these techniques are yet fully effective in spite of those quantitative uncertain factors which are difficult to evaluate. The accuracy of the measured value is allowed to be less precise unless that quantitative uncertainty produces the qualitative uncertainty which has a hindrance in the normal performance of the radiation protection activities. This important understanding, being interdependent with the necessity of simplification of the techniques, can make a drastic improvement of measurement method really possible. From the standpoint mentioned above, the authors gave a typical example of the simplified method of urinary uranium analysis using sodium fluoride pellet, in which the trouble was remarkably saved and the time required for analysis was shortened to one third of that of the former method.
