| 内容記述 | A nasal swab sample, which is taken immediately after an inhalation accident of radioactive aerosols, shows provisional intake radioactivity. In the case of an alpha emitter, much time is needed to determine the intake radioactivity using bioassay. A nasal swab sample would be expected to be a determination method for early dose estimation. In this study, the most hazardous size to our health and how to estimate the exposure dose were considered from the viewpoint of emergency medicine. A computer code, LUDEP, was used to calculate the aerosol deposition in respiratory tract and the committed effective dose. Assuming that the radioactivity detected in a nasal swab sample was equal to the radioactivity deposited in the extrathoracic region 1 (ET1), the dose conversion factor (DCFnasal) was evaluated based on the relationship between the ET1 deposited radioactivity in Bq and the committed effective dose in mSv. The DCFnasal showed a clear dependency with the aerosol size. It was indicated that a reference aerosol size of 5 µm for occupational exposure in the ICRP publication was not always safe dose estimation for patients. In the case of insoluble plutonium-239, the maximum value of 2.6 mSv Bq-1 for DCFnasal was found at 0.02 µm in a heavy exercise level of an adult. Therefore, this indicated that the maximum value would make possible rapid dose estimation for nuclear emergency medicine. | |||||
