Report on Radiation Survey of Komori Production Facilities (As of April 12, 2011)

Monday 18. April 2011 - Today Komori Corporation issued a report on radiation surveys conducted on April 8 and 12, 2011 at the Tsukuba Plant, Komori Machinery and Komori Electronics.

1. A total of 21 points in the factory were measured for radiation intensity at the Tsukuba Plant on April 8, 2011. The measured values were between 0.04 and 0.10 microsievert per hour (microSv/h) (average was 0.068 microSv/h) and no abnormal levels have been reported.
An examiner from the Japan Marine Surveyors & Sworn Measurers’ Association measured all of these points using the following measuring equipment.
“Aloka” Scintillation Survey Meter TSC-171
2. At the Komori Machinery and Komori Electronics facilities, a total of 13 points were measured for radiation intensity on April 12, 2011. The measured values were between 0.03 and 0.06 microSv/h (average was 0.035 microSv/h) and no abnormal levels have been reported.
The examiner from the Japan Marine Surveyors & Sworn Measurers’ Association measured all of the above points using the following measuring equipment.
“HORIBA” Scintillation Detector PA-300 Radi
Measurements were taken at both 1 meter high and floor level at all points.
We will continue to provide updates whenever necessary.
To provide a perspective, the following illustrate the ionizing radiation dosage a person can absorb for common sources.
Sleeping next to someone: 0.05 microSv
Eating one banana: 0.1 microSv
Chest X-Ray (1 time): 20 microSv
Airplane flight from New York to Los Angeles: 40 microSv
