520 Bq/kg of Cesium in Spinach in Fukushima City, Cesium Is From Polyethylene Covering
News like this may be part of the reason of Professor Hayakawa's hostility toward farmers in Fukushima.
Where did this cesium come from? Water? Air? Soil?
Answer: None of the above. It came from a polyethylene sheet covering to keep the crop warm.
What is wrong with the sheet? It is the same polyethylene sheet that was in use when the reactors blew up in Fukushima I Nuclear Power Plant in March last year.
Why did the farmer continue to use the contaminated sheet? No one knows. Probably because no one told him not to use.
The spinach in question has already been sold, and probably consumed.
From Yomiuri Shinbun (4/11/2012):
福島県は１１日、福島市の露地栽培のホウレンソウから、国の食品規制値（１キロ・グラムあたり１００ベクレル）を超える放射性セシウムが検出されたと発表した。
Fukushima Prefecture announced on April 11 that radioactive cesium exceeding the national safety limit (100 becquerels/kg ) was detected from spinach grown in Fukushima City.
ホウレンソウは福島市内の直売所に出荷されており、県は回収を呼びかけるとともに、福島市に対し、出荷自粛を要請した。
The spinach is sold at the direct sales depots in the city. The prefectural government is recalling it, and has asked Fukushima City to voluntarily halt shipment.
県によると、福島市の農家で６日に収穫されたホウレンソウから１キロ・グラム当たり５２０ベクレルの放射性セシウムが検出された。ホウレンソウは３月２６日～４月６日に、計２１キロ・グラムが農産物販売所に出荷された。
According to the prefectural government, 520 becquerels/kg of radioactive cesium was detected from spinach harvested on April 6 at a farm in Fukushima City. The total 21 kilograms of the spinach from this farm were shipped to the farm produce sales depots between March 26 to April 6.
ホウレンソウ栽培で使う保温用ポリフィルムは、昨年３月の原発事故以降同じものが使用されており、１キロ・グラム当たり３１万ベクレルと高濃度の放射性セシウムが検出された。県は保温材から放射性物質が付着した可能性が高いとみている。
Spinach growers use polyethylene sheet to keep the crop warm. The farm had been using the same sheet ever since the nuclear accident in March last year. 310,000 becquerels/kg of radioactive cesium was detected from the sheet. According to the prefectural government, it is highly likely that radioactive materials on the sheet were transferred to the spinach.
Last year, spinach from Fukushima in March and April regularly tested with thousands of becquerels/kg of radioactive cesium, in addition to radioactive iodine. A quick browse at Fukushima Prefecture's site on agricultural products found 34,000 becquerels/kg of radioactive cesium in spinach.
NHK, on the same news, says the prefectural government is doing an emergency check on about 500 farms that produce spinach using the polyethylene sheet.
By now, you know this lack of thinking is not confined to farmers in Fukushima. Remember the subsidiary of Chiba JA (ag producer co-op) "recycling" the dirt attached to the plastic sheet used for greenhouses? The dirt was found with 58,000 becquerels/kg of radioactive cesium, but the dirt had been already sold to a tree nursery. I wonder what happened to the dirt.
