A geiger counter, measuring a radiation level of 0.163 microsievert per hour, is seen at Douhou Kindergarten, located about 50 km (31 miles) from the tsunami-crippled Fukushima Daiichi nuclear power plant, in Nihonmatsu, Fukushima prefecture February 25, 2013, ahead of the second-year anniversary of the March 11, 2011 earthquake and tsunami. As the World Health Organisation (WHO) says children in Fukushima may have a higher risk of developing thyroid cancer after the Daiichi nuclear disaster two years ago, mothers in Fukushima worry that local health authorities are not doing enough.
