0.44~9.31 μSv/h after explosion of Chemical complex

Following up this article..NISA investigated chemical complex in Iwakuni

Radiation level was picked up from 0.22~9.31 to 0.44~9.31 μSv/h around the depleted uranium after explosion. It was measured from 9:00 ~ 9:30 of 4/22/2012, when 7 hours had passed since first explosion.
9.31 μSv/h is extremely high. It shows it was severely radioactive even before explosion.

Depleted uranium was kept in 3379 of the 200 L drum cans, which are made of double stainless steel.
They were stocked in the warehouse located at 500m north west to the explosion point. From 1968 to 1973, they were used for catalyst containing uranium oxide in the process of manufacturing textile materials.
The blast broke the windows of the warehouse, but it is reported that the drum cans were not broken.

Iwakuni city government and Otake city government were not informed of the depleted uranium stocked in the chemical complex.
