Cesium-137 is a radioactive isotope of cesium. Cesium-137 was emitted from the explosion of the Fukushima Nuclear Power Plant, Japan, last month. It is known that the half life of Cesium-137 is 30.17 years. The decay of Cesium-137 follows the first-order kinetics. (1) Determine the reaction rate constant. (2) How long will it take to reduce the emitted quantity by one tenth?

In August 2013, radioactive water from the damaged Fukushima Daiichi nuclear plant leaked into the Pacific Ocean. The contaminated groundwater seeped through an underground barrier created through chemical injections, and the Japanese Nuclear Regulatory Authority declared an emergency. In response, Tepco (the plant's operator) began pumping out more groundwater to ease the spill into the ocean. Concentrations of cesium-137 (in Bq/l) in the seawater 10 - 30 kilometers off the Japanese coast were taken at eight different locations one week...
