Summary

The environmental consequences of the atmospheric release of radioactive materials from the accident at the Fukushima Daiichi Nuclear Power Station (FDNPS) were not sufficiently determined in the early stages of the accident, causing serious problems related to off-site countermeasures. One of the key questions faced not only by inhabitants in the affected areas but also by the public, including experts of relevant fields, is whether the confusion and problems in the emergency responses could have been avoided if the spatial extent and temporal evolution of the radioactive plume had been captured by monitoring. In this chapter, we will review the situation of the emergency preparedness related to the monitoring infrastructure at the time of the accident by examining whether the monitoring infrastructure was capable of coping with a large-scale nuclear disaster to determine an appropriate state of preparedness.
