Radionuclides from Fukushima has already hit the food, so far only in Japan
Japan has raised the standards of “safe” content in food radioactive cesium and iodine. But in food radiation already exceeds even these new norms. The content of radiocesium in Japanese products in 260 times higher than, for example, while in the Kaliningrad region nuclear-free. Andrei Ozharovsky, 19/03-2011
The chief Cabinet Secretary of Japan Yukio Edano (Yukio Edano) confirmed at a press conference today that the levels of radioactive contamination of food products exceed even installed yesterday “temporary” emission limits. According to him, the high level of radiation has spinach from Ibaraki Prefecture and milk from Fukushima Prefecture, the farm, located 30 kilometers from the nuclear power plant accident. Edano said that even these contaminated products do not pose a risk to health. However, contaminated products will be destroyed, and the Ministry of health instructed local authorities to investigate and prevent hazardous products on sale. “the Government will do all that needs to avoid health risks and to solve this problem», – said Edano at a press conference.
Experts note that ingestion of radionuclides inside the body the radiation effect is many times more destructive than external irradiation. Therefore, even relatively small doses can pose a serious threat. In addition, the radiation exposure is not deterministic and stochastic (probabilistic) in nature, that is, of course, not all of the consumers get sick of radionuclides, but, nevertheless, some vnutrennemu subjected to irradiation due to the consumption of contaminated food will of cancer and other associated with a radiation disease.
The Japanese ordered iodopropionic
Since a major concern is the content in foods of radioactive iodine-131, nuclear safety Commission of Japan on March 16 recommended local authorities to instruct the population on how to carry out iodine prophylaxis, i.e. intake of digestible by the human body stable (not radioactive) isotopes of iodine.
“As a method of prevention, intake of stable iodine can prevent the accumulation of radioactive iodine in the thyroid gland. Tablets with stable iodine syrup (for children) haibara available in the evacuation centers», – said in the report released today by the IAEA.
It should be noted that Russian nuclear scientists reject the need of iodine prophylaxis, and claim. Whatever the accidents and incidents at Russian NPPs no population evacuation or iodine prophylaxis is not required.
Improved standards for iodine and cesium
On 17 March, the Commission for food security of Japan has set elevated standards for temporary artificial radionuclides in food. Iodine-131 in drinking water, milk, milk products – 300 Bq/kg in vegetables (except potatoes) – 2000 Bq/kg For cesium-137 in drinking water, milk, milk products – 200 Bq/kg (for baby food – 100 Bq/kg), in vegetables, meat, eggs – 500 Bq/kg.
These new elevated Japanese standards quite correspond to the Russian. SanPiN 22.214.171.1248-01. 2.3.2. “raw and processed food products. Hygienic safety requirements and nutritive value of food products” sets, for example, for cesium-137 in meat and meat products “safe” level to 200 Bq/kg and for meat of wild animals even 300 Bq/kg.
It turns out that for Japan the norm time, inflated for the period of the disaster, for Russia – regular, full-time norm.
Bezadeih in the regions of radiation is thousands of times less
To assess the seriousness of the situation it is useful to compare the contents of radionuclides in products of Japanese with the situation in nuclear-free regions. For example, in the Kaliningrad region, now, before the construction of the Baltic NPP, the concentration of radiocaesium in drinking water in 2800 times lower than in the contaminated products of Japan, and in the agricultural products – 260 times below.
According to official data ‘currently in the agricultural products locally produced food (potatoes, milk) and fish specific activity of cesium-137 is 0.3 to 1.9 Bq/kg, in drinking water of public sources – 0,012-0,07 Bq/l” (EIA Baltic NPP, leaf 105).
However, if the Baltic NPP will be built, we should expect increased levels of cesium and other radionuclides in water and products – after all, current Russian regulations allow this…
