The Fukushima nuclear disaster in Japan is the most recent catastrophic nuclear disaster in memory which was brought about by the massive tsunami that was triggered by a magnitude 9.0 earthquake in Tohoku region in Japan last 2011. One of the radioactive substances released during the incident is cesium-137 which has a half-life of 30 years. Around 15,000 terabecquerels (becquerel is a standard unit of radioactivity named after Henri Becquerel) of Cs-137 was released during the disaster. How many becquerels of this radioactive substance remains to this day?
