On April 26, 1986, an explosion at the nuclear power plant at Chernobyl, Ukraine, released the greatest quantity of radioactive material ever associated with an industrial accident. (See the photo and discussion on pages 1190–1192.) One of the radioisotopes in this emission was ¹³¹I, a β^– emitter with a half-life of 8.021 days. Assume that the total quantity of ¹³¹I released was 250 g, and determine the number of curies associated with this ¹³¹I 30.0 days after the accident.
