Japanese officials have announced the discover of even more radioactive material beyond the confines of the Fukushima plant, this time a staggering 61km away. The material in question is strontium – and although detected in low levels, is dangerous.
Strontium 90 is particularly concerning, as it replaces calcium in the body’s skeleton, emitting beta rays from within, and has a half-life of 50 days. Not something you want in your dirt. [Kyodo News and Mainichi]
