A patient ingests 1.58 mg of I-131 (iodine-131), a beta emitter with a half-life of 8.0 days. Assuming that none of the I-131 is eliminated from the person's body in the first 4.0 hours of treatment, what is the exposure (in Ci) during those first four hours? Express with 2 significant figures.Thank you.
