Fukushima: Radioactive Gravel in Apartment Construction Contaminates Kids
Not reported in the US press - radioactive construction materials are causing move-out of people from new construction after kids had more radiation than other kids in the neighborhood. Nobody knew this would be a problem.
Officials in Fukushima Prefecture say they have detected high levels of radiation in a new building. They say a construction material may have been tainted with radioactive substances from the Fukushima Daiichi nuclear power plant.
The city checked the condo for radiation in December after regular monitoring found that children living there had been exposed to higher levels of radiation than other children over a 3-month period.
The city found that the radioactive cesium level on the first floor was 1.24 microsieverts per hour, which is higher than outside.
...gravel used on the first floor came from a stone-crushing site in Namie Town in an evacuation zone near the crippled plant.
The city says it will ask the tenants of the first-floor apartments to move out and will interview the other residents.
The Japanese government is investigating the distribution of crushed stones that may contain radioactivity from the accident at the Fukushima Daiichi nuclear power plant. It has found that concrete made of the stones has been sold to more than 200 firms.
The quarry operator says it shipped more than 5,000 tons of crushed stones to 19 firms in the weeks after the accident. The government has set no limit on radiation in stones and sand used for construction even after the nuclear accident.
The company president told reporters on Monday that he never imagined that stones from his quarry would cause such a problem and that he wants to apologize to residents of the building for their exposure to radiation.
The economy ministry says 2 of the 19 firms sold concrete made of the stones to more than 200 companies. It believes that the concrete was used in housing construction and on roads.
discovery of one particular concentration of radiation in Nihonmatsu, a town in the prefecture where many people displaced after March 11 have sought refuge, has provided an unexpected cause for alarm: In a six-month-old apartment development, unusually high radiation levels were detected not in surrounding air or soil, but inside the building itself.
The reason for the aberration? Rocks used to make the cement for the building’s construction originated from a quarry in the town of Namie, a coastal village that at its closest point is situated as little as five kilometers from the damaged Fukushima Daiichi nuclear plant.
during that six-week period – from March 14 to April 22 – that a giant pile of rocks to be mixed into cement sat in Namie, covered from outdoor elements only by a flimsy roof, according to an official at the government’s Nuclear Emergency Response headquarters on Monday. In that time about 5,200 tons of the rocks were shipped to 19 construction and cement companies. The gravel has since been used in various projects, one of them being the apartment complex in Nihonmatsu
a city-wide survey of children under 18, taken from September to November last year, showed one high school girl had been exposed to 1.62 millisieverts, higher than the annual 1 millisievert level permitted for the general public by the Japanese government in accordance with international safety standards. The cause of the spike was eventually, through subsequent tests, traced back to her home.

Radioactive Grasshoppers probably safe to eat, but exceeds govt standard for cesim. Eat bugs far away from the powerplant for least radiation.
With a Geiger counter in his pocket, Mr. Fugo, along with two students, in October went to Iitate, a village located over 30 kilometers away from the nuclear plant and where hot spots of high radiation have been discovered. ...About 4,000 becquerels of radioactive cesium-134 and cesium-137 was detected in the grasshoppers, all 500 weighing a cumulative one kilogram. The levels far exceed Japan’s regulatory limit of 500 becquerels per kilogram.
...scientist thinks it is safe to eat the bugs because they are usually in snack-sized portions ... amount of cesium dropped considerably after going through the routine steps taken when preparing the insects for consumption.
In contrast, radiation found in about 2,000 locusts collected further away, about 60 kilometers away from the plant, measured well below the government standard.
