Q How has the cesium concentration in the air changed since the accident?
-

Q Why Does the Air Dose Rate in Urban Areas Decline Quickly?
-

Q I heard lichens tend to capture cesium. What is the mechanism like? (2)
-

Q I heard lichens tend to capture cesium. What is the mechanism like? (1)
-

Q What kinds of radioactive materials were released into the atmosphere and the sea and how much?
-

Q Is there any chance that decontaminated areas may be contaminated again, increasing the air dose rates?
-

Q When soil generated by decontamination is stored in containers for a long time, is there any possibility that the soil may leak from the containers?
-

Q Is it possible for agricultural produce to be bred in areas where soil generated by decontamination was stored temporarily (former temporary storage sites), and will it be safe?
-

Q What efforts are you making to release the difficult-to-return zones where residents can feel safe?
-

Q Does radioactive cesium in edible wild plants reduce through cooking? If so, by how much?
-

Q I heard most of the forests would not be decontaminated. Does cesium remain in the forests?
-

Q Do radioactive cesium concentrations in trees increase over time? If so, can such trees be used as timber?
-

Q Did low-dose radiation exposure in Fukushima prefecture affect de novo mutations of the next generation of trees?
-

Q How is it considered that radioactive cesium-137 (137Cs) concentrations on the forest surface (forest floor) in Fukushima prefecture will change in the future?
-

Q What kind of changes did radioactive cesium in forest soil contaminated by the nuclear accident go through over 10 years since the accident?
-

Q Do radiation does will increase using bathing beach?
-

Q Does defoliation of forests affect the concentration of cesium dissolved in river water?
-

Q How is radioactive cesium deposited on land expected to move in the future?
-

Q Wouldn't radioactive cesium accumulated at the bottom of lakes, dams, etc. dissolve and affect the ecosystem and farming operations downstream?
-

Q How extent does radiocesium flowing in from rivers affect the coastal environment?
-

Q What is the current concentration of radioactive cesium in edible wild plants in Fukushima Prefecture?
-

Q How is the concentration of radioactive cesium in river fish changing over time?
-

Q How is the concentration of radioactive cesium in marine species changing?
-

Q What changes do you see in radioactive cesium concentrations in wild animals in Fukushima Prefecture?【Recent trend】
-

Q What kind of effects did the accident at the nuclear power station have on aquatic insects and freshwater fish that feeds on them?
-

Q What is tritium? What is it like?
-

Q Does tritium affect our bodies?
-

Q What are the initiatives for third-party analysis of ALPS treated water by JAEA under the national policy?
-

Q What happened to the inside of the reactor pressure vessel and storage vessel after the accident?
-

Q On performing fuel debris retrieval work, what kind of measures are taken to ensure the safety of workers?
