Please answer the following question: Q: The curie (ci) is one measure of the rate of what? Read this paragraph and choose the correct option from the provided answers: The curie (Ci) is one measure of the rate of decay (named after Pierre and Marie Curie). One curie is equivalent to 3.7 10 10 disintegrations per second. Since this is obviously a large and unwieldy number, radiation is often expressed in millicuries or microcuries (still very large numbers). Another measure is the becquerel (Bq) , named after Henri Becquerel. The becquerel is defined as an activity of one disintegration/second. Both of these units are concerned with the disintegration rate of the radioactive isotope and give no indication of dosage to the target material. Choices: - spin - division - growth - decay A:
Answer:
decay
