Bismuth-210 is beta emitter with a half-life of 5.0 days. |
Part A If a sample contains 1.3 g of Bi-210 (atomic mass = 209.984105 amu), how many beta emissions would occur in 13.5 days? Express your answer using two significant figures. |
Part B
If a person's body intercepts 5.6 % of those emissions, to what dose of radiation (in Ci) is the person exposed?
Express your answer using two significant figures.

Radioactive bismuth, Bi-210 (half-life of 5.0 days), decays to polonium, Po-210. Radioactive Po-210 (halflife of 138 days) decays to stable lead, Pb-206. a) Draw the decay scheme for Bi-210 to Po-210. b) Draw the decay scheme for Po-210 to Pb-206. c) If you start with 5.0 X 10-3 Ci of pure Bi-210, calculate the activity of Bi-210 and Po-210 after 30 days.

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.
