Cesium pollen has finally started attacking Tokyo, Saitama, and Kagoshima on Feb. 9, 2012. Because this winter is colder than usual, it is about 1 week later than average and the peek is estimated to be early in March.

Because the first week of February was extraordinary cold, pollen didn’t fly much but it started flying when it became warmer.

The pollen is estimated to contain 250Bq/g of cesium.

Foresty agency, Japanese government and mass media are downplaying the risk. Mainichi newspaper reported about it on 2/9/2012, but described this way.

Compared to 2011, the amount of pollen will be smaller.
Tokyo ▽35%
Saitama ▽40%
Kagoshima ▽25%

However, the amount of pollen in 2011 was extraordinary. The amount of pollen in 2012 will be the average amount. (Source)

Cesium pollen will increase the radiation level up to the last April level

Though Japanese government stated cesium pollen won’t affect your body, Ibaraki University and other laboratories are studying the effect of cesium pollen. Prof. Kita from College of Science, Ibaraki University assumes it is a possibility that radiation level goes up to the level of April in 2011.

From the research of Forestry Agency in last December, pollen from Namiemachi contains 253,000 Bq/Kg of cesium. Assistant prof. Higaki from Radioisotope center, the university of Tokyo says, mask for pollen allergy can stop 100% of cesium. Even though you breathe all the cesium contained in pollen, it won’t affect your body.

However, everyone suffers from hayfever though they wear mask. Also, there is no analysis about other nuclides contained in pollen.

Ibaraki university will finish their analysis around in early February, but by early February, pollen will have already started flying.
