A worker in a laboratory unknowingly became exposed to a sample of radio-labeled sodium iodide made from iodine-131 (beta emitter, t1/2 = 8.07 days). The mistake was realized 28 days after the accidental exposure, at which time the activity of the sample was 25.6 × 10-5 Ci/g. The safety officer needed to know how active the sample was at the time of the exposure. Calculate the activity value in Ci/g.

A worker in a laboratory unknowingly became exposed to a sample of radio-labeled sodium iodide made from iodine-131 (beta emitter, t1/2 = 8.07 days). The mistake was realized 28 days after the accidental exposure, at which time the activity of the sample was 25.6 × 10-5 Ci/g. The safety officer needed to know how active the sample was at the time of the exposure.

Calculate the activity value in Ci/g.

A worker in a laboratory unknowingly became exposed to a sample of radio-labeled sodium iodide made from iodine-131 (beta emitter, t1/2 = 8.07 days). The mistake was realized 28 days after the accidental exposure, at which time the activity of the sample was 25.6 x 105 Ci/g.
