Radioactivity and Air Dose Rate

(2013)

How has the distribution of air dose rates been investigated?

For measurement of air dose rates, appropriate methods for investigation have been applied according to spatial resolution of the method and the scale of the area: from wide regions to specific spots.

◆ Airmonitoring : Radiation detectors are loaded on a helicopter

航空機モニタリング

◆ Car-borne survey, Person-borne survey : A radiation detector is loaded on a car or on a person.

走行サーベイ

◆ Survey meter : Air dose rate in a spot depending on the radiation level.
