Fukushima nuclear radiation entering the food chain
Cesium-137 and strontium-90 both have half-lives of about 30 years, making it more likely theywill eventually enter the food chain and affect the
health of consumers, the environmentalprotection department said.
Nuclear contamination threatens seawaters, By Wang Qian (China Daily) 16 Aug 2011, BEIJING – China’s seawaters are at risk of being contaminated by radioactive materials comingfrom the Japanese
nuclear power plant that was seriously damaged in the large earthquakethat struck in March, China’s ocean watchdog said.
The State Oceanic Administration’s environmental protection department told China Daily thatChina will strengthen its
monitoring for radioactive substances in the waters east of Fukushima,where the nuclear plant is, and in the East China
Sea. By doing so, they hope to forecast whateffect the radiation released by the plant will have on the marine environment
and the safety ofmarine food.
The latest monitoring result released by the State Oceanic Administration on July 29 showedthe first group of seawater
samples collected from the area contained 300 times the amount ofradioactive cesium that is found in nature and 100
times the amount of strontium…..
About 60,000 tons of water have been used to lower the temperature of the six reactors at theplant. The March
earthquake and subsequent tsunami caused some of the plant’s reactorcores to melt down after fuel rods there had
become overheated, according to the FukushimaNuclear Accident Update Log that was released by the International
Atomic Energy Agency onApril 11.
The State Oceanic Administration said the marine organisms in the places that are being monitored have been contaminated to different extents. Those that live near the surface are ata greater risk of being
affected.
Cesium-137 and strontium-90 both have half-lives of about 30 years, making it more likely theywill eventually enter the food chain and affect the health of consumers
, the environmentalprotection department said.
Researchers will continue to try to protect public health by monitoring and gauging the effect ofthe radiation release on
China’s marine environment, according to the department…..
