What does one gigabecquerel represent?

One gigabecquerel is an SI derived unit of radioactive activity equal to one billion becquerels or one billion nuclear decays per second.

Why use millicurie instead of becquerel?

Millicurie is commonly used in nuclear medicine and radiopharmaceutical applications due to its convenient scale for activities typically administered or measured.

Is the conversion between GBq and mCi exact?

The conversion rate is fixed at 1 GBq = 27.027027027 mCi, but practical use may require attention to rounding and isotope specifics.

Key Terminology

Gigabecquerel (GBq): An SI derived unit of radioactive activity representing 10^9 becquerels, where each becquerel equals one nuclear decay per second.
Millicurie (mCi): A non-SI radioactive activity unit equal to one thousandth of a curie, corresponding to 3.7×10^7 disintegrations per second.
Radioactive Activity: A measure of the rate at which a radioactive source undergoes nuclear decay, expressed in units such as becquerels or curies.
