How to Search for food data

 

 
 On the MDS, you can search current data from independent radioactivity measurement laboratories in Japan
that are participating as project members. The data is successively added and updated.

You can search data by using four factors: item, value, place, and date. If you do not specify a factor
which means a "blank search," you can search all entries in each factor.

If you don’t specify a place, data for the entire country is shown.

1.Item

 You can select and click on an item (generally the type of food).
   The list of items was originally created by the MDS, referring to various food classifications, and will be regularly
   modified and added to. Samples of types that are not measured frequently are classified as “Other.”  


2.Value
 
  You can set the range of upper and lower limits of the total value of Cesium 134 and 137 or the value of Cesium 137 alone.


3.Place

 You can make multiple selections by pressing the shift key.
   In principle, “place” means place of production, but in some cases, it indicates the place of purchase.


4.Date

You can select the year and month of the measurement to narrow the search. Each measurement result relies
on the measuring information provided by each laboratory. Radioactivity measurements always have a range of error.


Remarks:

-You should understand that the results can vary even if multiple measurements were conducted under identical conditions.

-The value of measurement error is set as 2σ by the MDS standard.

-At present, the shared database includes data on food measurement only, but sharing results obtained from environmental
 samples such as soil is under consideration.


*The data accuracy of each measurement laboratory has been checked
 by via the brown rice standard, as described above, under the guidelines of the MDS.
