Utilizing a novel mobile monitoring system installed on a community minibus, the study employed a cost-effective sensor, namely, Pocket Geiger which was integrated with a microcontroller and telecommunication system for data transfer, access, visualization, and accumulation. The study area included the region between Okuma and Tomioka towns. The ambient dose rate recorded along the minibus route was depicted on a map, averaged within a 1 \u00d7 1 km mesh created with the Quantum Geographic Information System. To ensure accuracy, the shielding factor of the minibus material is determined to adjust the dose readings. A significant decrease (p &lt; 0.001) in the radiation dose ranges from 2022 to 2023 was observed. The land use classification by the Advanced Land Observation Satellite revealed an ecological half-life ranging from 2.41 years to 1 year, suggesting a rapid radiation decay across all land types. This underscores the close connection between radiation attenuation and environmental factors, as well as decontamination efforts across diverse land categories.<\/jats:p>","DOI":"10.3390\/s24051375","type":"journal-article","created":{"date-parts":[[2024,2,21]],"date-time":"2024-02-21T04:23:10Z","timestamp":1708489390000},"page":"1375","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Low-Cost Sensor Deployment on a Public Minibus in Fukushima Prefecture"],"prefix":"10.3390","volume":"24","author":[{"given":"Rakotovao Lovanantenaina","family":"Omega","sequence":"first","affiliation":[{"name":"Graduate Program in Nuclear Science and Engineering, Faculty of Mathematics and Natural Sciences, Bandung Institute of Technology, Bandung City 40132, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7284-0381","authenticated-orcid":false,"given":"Yo","family":"Ishigaki","sequence":"additional","affiliation":[{"name":"Research Center for Realizing Sustainable Societies, The University of Electro-Communications, Tokyo 182-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sidik","family":"Permana","sequence":"additional","affiliation":[{"name":"Graduate Program in Nuclear Science and Engineering, Faculty of Mathematics and Natural Sciences, Bandung Institute of Technology, Bandung City 40132, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshinori","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Department of Applied Physics and Physico-Informatics, Faculty of Science and Technology, Keio University, Yokohama 223-8522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9609-8871","authenticated-orcid":false,"given":"Kayoko","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Graduate School of Information Science and Technology Department of Informatics, The University of Electro-Communications, Tokyo 182-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katsumi","family":"Shozugawa","sequence":"additional","affiliation":[{"name":"Graduate School of Arts and Sciences, The University of Tokyo, Tokyo 153-8902, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6674-2662","authenticated-orcid":false,"given":"Mayumi","family":"Hori","sequence":"additional","affiliation":[{"name":"College of Arts and Sciences, The University of Tokyo, Tokyo 153-8902, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,21]]},"reference":[{"unstructured":"Britannica (2024, February 03).
