About the units
What is a millicurie?
One-thousandth of a curie (3.7×10⁷ Bq = 37 MBq). A typical unit for nuclear-medicine doses in countries using the curie.
What is a megabecquerel?
One million becquerels (10⁶ Bq). Nuclear-medicine doses are usually given in megabecquerels — e.g. a few hundred MBq for a scan.
