| ♦ | In summer in 2012, Cicadas sang so loud as usual. However, I felt numbers of cicadas were a little bit less than that of last year. |
| ♦ | Comments from the ranger of the forest: I feel sure that numbers of cicada seems to be a little bit less than that of last year. However, we must pay attention that this year is especially uncommon year in the lunar calender: this year has an intercalary month on May, so May came twice in this year. From ancient days, people said that seasonal changes in this kind of year in lunar calender are quit differnt from usual year and there are explicit effects on living creatures. Therefore, we should not conclude "radiation effects on cicadas are found" only considering with the short term observation. We should observe more long period in order to know real effects of radiation dose on living creatures. |
| ♦ | Because Kotori no Mori is not a park but a forest, this forest was excluded from the target of decontamination. Therefore, the radiation level was still high. Hence, children rarely visit this forest still now. |
| ♦ | The dose meter at the parking area of the forest showed 1.697μSv/h. |
