Welcome to Environmental Radioactivity Datasets website at CRiED, Univ. of Tsukuba

Important notice on dataset correction
19th November, 2021

Dear user of DOI ENVRAD database site,

The data set of 10.34355/CRiED.U.Tsukuba.00085 was revised following the data correction. The reasons for the data correction are due to the following 2 reasons.

- One of the data provider announced its failure and 144 tritium records were corrected.

- One of the database users informed us that some of the records are not records of sea water, but of precipitation. We looked at the data source carefully and found that 66 records downloaded from the IAEA Maris are not seawater records. Then the 66 records are removed.

We prepare a corrected file and put it into the download package of 10.34355/CRiED.U.Tsukuba.00085 with a document in which we describe details of corrections.

We apology any inconvenience due to this.

Best regards,

Michio Aoyama, Prof., the representative of DOI ENVRAD publisher at Univ. of Tsukuba
