Here are the essential concepts you must grasp in order to answer the question correctly.
Radioactivity
Radioactivity is the process by which unstable atomic nuclei lose energy by emitting radiation. This emission can occur in various forms, including alpha particles, beta particles, and gamma rays. The rate of decay is measured in terms of activity, which indicates how many disintegrations occur per second, typically expressed in units like becquerels (Bq) or curies (Ci). Understanding radioactivity is essential for comparing the radiation output of different samples.

Units of Measurement
In the context of radioactivity, two common units of measurement are the becquerel (Bq) and the curie (Ci). One becquerel is defined as one disintegration per second, while one curie is equivalent to 37 billion disintegrations per second. To compare the activity of the two samples effectively, it is crucial to convert them into the same unit, allowing for a direct comparison of their radiation output.

Radiation Dose
Radiation dose refers to the amount of radiation energy absorbed by a material or biological tissue. It is important to consider not just the activity of a radioactive sample but also how that activity translates into potential biological effects. The higher the activity, the greater the potential radiation dose, which can impact safety and health in environments where radioactive materials are present.
