Concept explainers
Interpretation:
The activity of americium-241 (241Am) in becquerels and in microcuries, is to be determined.
Concept Information:
The number of decays per second tells the activity of the radioactive material. Becquerels (Bq) is the SI unit of activity.
The number of radioactive nuclei (N) is experimentally proportional to activity.
Here,
The change in the number of nuclei per second is:
Here,
The above equation is called the law of radioactive decay which is a first-order kinetic process. The half-life of the first-order reaction is:
Here,
The relationship between the conversion of grams to milligrams is as:
The relationship between the conversion of becquerel to curie is as:
The relationship between the conversion of curies to microcuries is as:
