| Outline of Final Research Achievements |
Radiation contamination in the sediment of Tokyo Bay was identified on the basis of measurement of Cs137 after taking sediment core samples at the head of Tokyo Bay. End-point of the radiation contamination was then identified, followed by evaluation of its relative risk in terms of loss life expectancy through comparison with other risks, including traffic accident. It was found that the risk of radiation contamination of the sediment is basically considered as low but when concrete information is provided, the concern tends to increase and willingness to pay for countermeasures also tends to increase.
