How many becquerels is equivalent to 1 Curie?

The correct conversion for the relationship between curies and becquerels is that 1 Curie is equivalent to 3.7 x 10^10 becquerels. This is based on the definition that 1 Curie represents the amount of radioactive material that decays at a rate of 37 billion decays per second, which directly correlates to the unit of becquerels.

In terms of understanding the scale of the measurements, becquerels (Bq) is the SI unit measuring radioactivity, defined as one disintegration per second. The curie, an older unit, was originally based on the radioactivity of 1 gram of radium-226, which leads to the higher numerical values when converted to becquerels.

The other choices do not represent the correct conversion of Curie to becquerels. For example, 37 GBq translates to a different numerical order since 1 GBq is 10^9 Bq, making 37 GBq equivalent to 3.7 x 10^10 Bq, which isn't a direct representation of 1 Curie by itself. Therefore, understanding the foundational conversion helps in aligning the units of measurement in radiology and provides clarity in various clinical
