No Fukushima radiation effect on bulls' sperm: Study
TOKYO (AFP) - The testes and sperm of bulls abandoned in the evacuation zone around the battered Fukushima nuclear plant were not affected by chronic exposure to radiation, a Japanese academic study has found.
The work provides crucial data to scientists and public policy advisers on the possible impact of the reactor meltdowns on human - and especially reproductive - health, two-and-a-half years after the tsunami-sparked disaster.
A team of researchers examined two bulls caught in September 2011 and January 2012 within a 20-kilometre radius of the plant, an area that was completely evacuated because of fears over radioactive risk.
They also looked at a male foetus from the area to help determine the effects of prolonged radiation exposure associated with the disaster, the world's worst since Chernobyl in 1986.
