Extremely high radiation levels of more than 250,000 becquerels per kilogram of radioactive cesium have been detected in male flowers of cedar trees in the no-entry zone near the damaged Fukushima Daiichi nuclear power plant.

 

Japan’s forestry agency collected male cedar flowers at 87 locations in Fukushima Prefecture from late November to early December to measure the levels of radioactive cesium.

 

The agency detected 253,000 becquerels of the radioactive substance per kilogram in the flowers collected at Omaru in the town of Namie, 11.3 kilometers from the plant. 29 locations saw levels exceed 10,000 becquerels.

The maximum amount of cedar pollen measured in the air when in season by the environment ministry was 2,207 grains per cubic meter.

 

 

The forestry agency says if people breathe this concentration for 4 months they would be exposed to 0.553 microsieverts of radiation.

The agency reports this is not a great health hazard as it is only about 10 times what a person would be exposed to from normal background radiation in Tokyo’s Shinjuku Ward.
