3,000 Bq/kg of Uranium238 and 240 Bq/kg of Uranium235 from air conditioning filter in Tokyo

3,000 Bq/Kg of Uranium238 and 240 Bq/Kg of Uranium 235 were measured from the dust stuck to the air conditioning filter in Tokyo.

Uranium 235/238 is 8%, which is enriched uranium from Fukushima.

It was from an apartment on 20th floor, located at 300m from Tokyo tower.

Tokyo tower is 227.4km from Fukushima, 350m from Russian Embassy.

The owner of the apartment evacuated right after 311 and came back 7 months after 311 to turn on the air conditioner. The filter took only air inside of the room.

Result

・Uranium 238 (Dr. C Busby presumed it from Thorium 234, which is the daughter nuclide of Uranium 238) : 3,000 Bq/Kg

・Uranium 235 : 240 Bq/Kg

・Cesium 134 : 42,000 Bq/Kg

・Cesium 137 : 68,000 Bq/Kg

・Lead 210 : 7,500 Bq/Kg [cf. Breaking news : 8400 Bq/Kg of lead-210 was measured from sample of Yokohama]
