Suppose that an 85.0 laboratory animal ingested 10.0 of a substance that contained 2.45% by mass , an alpha emitter with a half-life of 24,110 years. What is the animal's initial radiation exposure in Curies? If all of the energy from the emitted alpha particles is absorbed by the animal's tissues, and if the energy of each emission is what is the dose in rads to the animal in the first 4.0 hours following the ingestion of the radioactive material? Assuming a biological effectiveness factor of 20, what is the 4.0-hour dose in rems?
