In the surrounding area of the FDNPS, dust samplers have been used as a means of monitoring the radionuclides concentration in the air. However, the installation of dust samplers requires a power supply, which limits the number and location of the samplers. We aim to establish a method to evaluate the radiocaesium concentration and behavior in the air using moss bags, which have been used in air pollution research. Since the moss bags can be easily installed at any place and time, the establishment of the evaluation method using the moss bags will be effective in creating a sense of security among the local governments and their residents around the FDNPS. In this study, we investigated the applicability of moss bags to the evaluation of the concentration and behavior of radiocaesium in the air.
