Question:

Refer to the Integrative Example. Another radioisotope produced in the Chernobyl accident was ¹³⁷Cs. If a 1.00 mg sample of ¹³⁷Cs is equivalent to 89.8 millicuries, what must be the half-life (in years) of ¹³⁷Cs?

Integrative Example

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. 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.
