Database for Radioactive Substance Monitoring Data

Environmental Monitoring Data

Dose Rate / Accumulated Dose

Measured air dose rate data, i.e. the amount of radiation per unit time in the air (nGy/h, or μSv/h). The air dose rate is continuously observed around the nuclear facilities to detect abnormality including radioactive substance leakage.

Survey Meter (ambient dose equivalent rate)
Vehicle-borne Survey
Airborne Monitoring [air dose rate]
Monitoring Post and Realtime Dosimeter

Soil

Measured data of radioactive substances released to the environment by Fukushima Daiichi NPP accident including ground deposition, radioactive concentration of soil sample and environmental sample, and radioactive substance depth distribution.

In-situ Measurement
Airborne Monitoring [cesium deposition density]
Soil / Environment Sample Analysis
Survey of Depth Distribution in Soil

Land Water

Measured data of radioactive substance in the water including river water, lake water, suspended sediment, river sediment, aquatic organisms, and stem flow in the forest.

River / Lake / Forest
Aquatic Organisms in Fresh Water

Food

Data of radioactive substances measured to maintain our safety and security of food including agricultural products, livestock products, fishery products, processed food, and drinking water.

Geographical Information

Elevation

The elevation data obtained in constant intervals by the airborne laser survey. The elevation data indicate vertical distances from "Japanese Vertical Datum" to measurement points on the ground surface without buildings or trees. This data is utilized as a base source to distinguish terrain.

Altitude

Vegetation

The data that indicate main species in plant community including forest and grassland.

Vegetation

Accumulated Snow

The data about accumulated snow status detected by microwave from the artificial satellite.

Snow Accumulation

Land-use

Condition or usage of land including "Forest", "Paddy", "Urban area", "Dry field", and "Grassland".

Land Use

Soil

The data of soil covering land surface that are classified by components or petrology. Soil is formed by disintegration of rocks, deposition of organic matters, and decomposition of microorganism.
