Question: 1 / 400

How many millicuries are equivalent to one curie?

10 mCi

100 mCi

1,000 mCi

One curie (Ci) is defined as the amount of radioactivity corresponding to the decay of 3.7 × 10^10 disintegrations per second, which represents a specific unit of activity. When converting curies to millicuries, it is important to recognize that the prefix "milli-" denotes a factor of one-thousandth (1/1000). Therefore, to convert one curie into millicuries, you multiply by 1,000.

This means that one curie is equivalent to 1,000 millicuries (mCi). Thus, when presented with the question of how many millicuries are in one curie, the correct response is indeed 1,000 mCi. Understanding these units of measurement is crucial in radiographic testing, as it helps professionals accurately quantify and communicate levels of radioactivity in various applications.
