Reuters, March 5, 2013: [Fukushima Daiichi's] damaged reactors still seep radiation, although at a rate of 10 million Becquerel per hour for cesium versus about 800 trillion right after the disaster. Becquerel per hour measures the amount of radiation emitted or the rate of radioactive decay. As atomic isotopes decay, they spin off energized particles that can penetrate human organs and damage human cells, potentially causing cancer.
