Japan earthquake: Fukushima radiation scans for babies

It's nearly five years since the Japanese earthquake and tsunami that led to the Fukushima nuclear disaster but concerns about possible health problems - especially in children - are still high in many parents' minds.

To reassure the public, scientists have developed a special scanner to accurately measure the amount of radioactive material inside the bodies of young children.

Now the results of over 2,500 scans have just been released.
