On March 22nd 2011, as part of monitoring activity of the surrounding
environment, we conducted nuclide analysis of radioactive materials
contained in the air which were collected at the site of Fukushima
Daiichi Nuclear Power Station, which was damaged by
Tohoku-Chihou-Taiheiyo-Oki Earthquake. As a result, radioactive
materials were detected and therefore, we summarized the results and
reported them to Nuclear and Industry Safety Agency as well as to
the government of Fukushima Prefecture.
(previously announced)
From March 31st to April 4th 2011, we conducted nuclide analysis of
radioactive materials contained in the air which were collected on
the same date at the site of Fukushima Daiichi Nuclear Power Station.
As a result, radioactive materials were detected as shown in the
attachment. Therefore, we summarized the results and reported them
to Nuclear and Industry Safety Agency as well as to the government
of Fukushima Prefecture today.
Three nuclides (Iodine-131, Cesium-134 and Cesium-137) are released
as fixed figures. Other nuclides figures are to be released as soon
as identified under instruction of NISA.
We are planning to conduct these surveys continuously.
