Text of Situazione T¨ Giapponesi

  • Japan Tea Exporters Assn.

  • Situation of Japan after 11th March 2011

  • Hydrogen explosions scattered radio active substances in the air!

  • Radio active substances from Fukushima NPP

    11th March : Massive Earth quake & Tsunami attacked North East Japan

    12th March : Fukushima Daiichi NPP Unit 1 Hydrogen Explosion

    14th March : Fukushima Daiichi NPP Unit 3 Hydrogen Explosion

    15th &16th March : Fukushima Daiichi NPP Unit 4 got fire

    4th 10th April : Put out contaminated water into the ocean

    Radio active substances have been emitted into the air from Unit 1 & 3, and will not stop for the time being.

    So, how much radio active substances are falling down on our tea gardens in Japan?

  • Major tea producing areas in Japan

    Distance between Fukushima

    Daiichi Nuclear Power Plant to

    Shizuoka is 350Km

    Kyoto is more than 500Km

    away from the site.

  • Environmental radiation surveillance (falling substances during regular period)

    Everyday, all prefecture report total amount of radio active substances falling on land to the Ministry of Education, Culture, Sports, Science & Technology.

    These data are available from the internet web sites.

    We use these data for estimation of radio active substances on tea leaves.

  • Please Buy Japanese tea for supporting recovery of Japan

  • Cesium is found in tea leaves from Kanagawa prefecture

    20th March - 3rd April Total 551MBq/Km2 of Cs137 falling on Chigasaki City in Kanagawa. (551MBq = 551,000,000 Bq)

    443tons of fresh tea leaves are harvested from 1Km2 tea garden during 1st flush season. (443tons = 443,000 Kgs)

    Maximum possibility of Cs 137 in tea leaves from Kanagawa is 551 ,000,000 / 443,000 = 1,244 Bq/Kg

    Actual data are all bellow CODEX Guide Line Minami Ashigara City 550Bq/Kg, & 570Bq/Kg, Odawara City 780Bq/Kg, Aikawa Town 670Bq/Kg, Manazuru Town 530Bq/Kg, Yugawara Town 680Bq/Kg, Kiyokawa Village 740Bq/Kg
