Radiation Measurement for Fukushima Revival

Radiation measurement in East Japan using a GM-tube detector after the Fukushima nuclear accident

A commercially available GM-tube detector calibrated with a Cs-137 standard source was used to determine the status of environmental radioactive contamination caused by the Fukushima nuclear accident. The calibration was achieved with a quadratic correction function for dose rates up to 4 Sv/h. The calibrated GM-tube detector was used for measuring air dose rates and ground surface contaminati...

Radiation protection: where are we after Fukushima?

Fukushima daiichi nuclear accident and radiation exposure.

We consider that the Great East Japan Earthquake was a combined disaster involving earthquake and tsunami as well as the release of radioactive materials into the environment (Fig. 1). Something I would like you to notice here is that among various disasters, a radiation nuclear disaster cannot be seen; it cannot be felt; in fact it cannot be detected without special devices. Because of that, t...

Radiation Distribution Measurements in Fukushima Prefecture

On March 11, 2011, a huge tsunami caused by the Great East Japan Earthquake destroyed all the electrical power facilities in the Fukushima Daiichi nuclear power plant. As a result, the reactors were badly damaged, and radioactive particles were widely scattered in the surrounding areas. In order to study the behavior of the radioactive particles emitted from the Fukushima Daiichi nuclear power ...

Radiation-Driven Migration: The Case of Minamisoma City, Fukushima, Japan, after the Fukushima Nuclear Accident

The emigration of residents following the Fukushima nuclear accident has resulted in aging and depopulation problems in radiation-contaminated areas. The recovery of affected areas, and even those areas with low radioactive pollution levels, is still heavily affected by this problem. This slow recovery consequently affects immigration patterns. This review aims to present possible factors that ...
