We have periodically measured radioactivity of the air and seawater near 
the power station, environment samples such as the soil and pine needles 
as analyses of environment samples*. While we have detected slight amounts 
of radioactive materials such as cesium and iodine emitted into the air by 
the accident at Fukushima Daiichi Nuclear Power Station, they are below 
the level to give significant effects on the surroundings.
            (Previously announced on April 13, May 13, 26, June 14 and 23)

We reported the measurement results of environment samples for 1Q to 
Niigata Technical Communications Conference. Then we have received the 
evaluation on the report from the conference which has concluded that no 
influence by Kashiwazaki Kariwa Nuclear Power Station has been confirmed 
and that the detected artificial radioactive materials will not make any 
impact on human health. The measurement results and the evaluation results 
are as attached.

We will continue to measure radioactivity of the environment samples 
periodically.

* Analyses of environment samples
We periodically conduct surveys on radioactive materials contained in such 
as seawater near the power station, soil, pine needles and milk in 
accordance with the "Agreement regarding ensuring security of the area 
surrounding the nuclear power station" (known as "Security Agreement").
