内容記述 | The deposition of radon decay products in each respiratory region can increase the lung cancer risk. Therefore, it is necessary to calculate the deposition of radon decay products in respiratory regions. Nowadays, the deposition in each respiratory region is able to be imitated using wire screens in many studies. Those studies employed grab sampling, that is, sampling for short period less than several minutes. In natural environment, because the concentration of radon decay products changes with time, it is necessary to measure continuously. In this study continuous dosimeter (CD) that imitates deposition of radon decay products in respiratory regions by using wire screens was developed for the purpose of estimation of the deposition in respiratory regions in various environments. The ratio of activities deposited in the simulated N and TB regions was calculated from results of measurement by CD-R, CD-N and CD-TB continuously, so that after aerosols were injected into the radon chamber, the ratio of N and TB depositions decreased, and, in addition, N / (N+TB) deposition decreased. These results indicated that CD-R, CD-N and CD-TB could measure the change of deposition ratio with time. |
