Define the animal''s initial radiation exposure in curies

Reference no: EM13527101

Suppose that an 90.0 ,gram laboratory animal ingested 12.0 mg of a substance that contained 2.60% by mass Pu-239, 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 7.77*10-12 . what is the dose in rads to the animal in the first 4.5 hours following the ingestion of the radioactive material?
