Cs-137 in forests ecosystems contaminated by the Fukushima Daiichi Nuclear Power Plant Accident

We developed a dataset for radiocaesium (¹³⁷Cs) in trees, soil, and mushrooms measured in the forests affected by the Fukushima nuclear accident. The ¹³⁷Cs activity concentration and inventory data reported in scientific journal papers written in English or in Japanese, governmental reports, and governmental monitoring data on the web were collated. The ancillary information describing the forest stands were also collated, and environmental information was derived from the other databases using longitude and latitude coordinates of the sampling locations.

The database consists of three separate files: 1) a data file, which contains radioactivity and ancillary data, 2) a field-description file, which explains the contents of the data file and the units of data, and 3) a reference list file, which contains the source number and the details of the reference. When the source has only a Japanese title, we translated the title into English, and included both titles in the reference list file.

Version 1.1

More descriptions have been added in "fields-description", and the data entry errors found in the review process have been modified.
