Pctures of radioactive dating
A member of the media, wearing a protective suit and a mask, looks at the No.3 reactor building at Tokyo Electric Power Co's (TEPCO) tsunami-crippled Fukushima Daiichi nuclear power plant in Okuma town “Contaminated water floating around and posing a constant risk of leaks disturbs the steady progress toward decommissioning,” said Yuichi Okamura, a general manager.If the half life is '3 years', then each tick mark on the graph represents 3 years.On the other hand, if the half life is '4 minutes', then each tick mark on the graph represents 4 minutes .More than 160,000 people were evacuated from their homes after the disaster, with most still unable to return due to contamination.Polish professional photographer Arkadiusz Podniesinski visited the site last month to “present the actual state of the exclusion zone,” capturing images from the ghost towns of Futaba, Namie and Tomioka.In the nearby town of Tomioka, hunter Shoichiro Sakamoto leads a team of 13 assigned to catch and kill the wild boars with air rifles.Twice a week, they set about 30 cage traps, using rice flour as bait.
Just as delicate and longterm is the impact that the 2011 nuclear crisis is likely to continue to exert over communities from the Fukushima region, where a 12-mile exclusion zone was imposed around the plant shortly after the disaster.
“We will bring an end to the problem by 2020.” Plant operators have been working to cut groundwater infiltration to about 150 tonnes a day – nearly a third of the amount generated two years ago – by pumping it upstream and directing it to the ocean.
The clean-up is expected to take a step forward within the coming month, when operators hope to obtain approval from regulators to activate an “ice wall” to block the flow of contaminated water.
It was at 2.46pm on March 11, 2011 that Japan was hit by a 9.0 magnitude earthquake, triggering a major tsunami which devastated the northeast coast and led to the loss of 19,000 lives.
The Fukushima plant was badly damaged in the disaster, which knocked out its power to the plant’s crucial cooling systems, resulting in meltdowns in three of its reactors, local evacuation and widespread concerns surrounding radiation contamination.
