About Becquerels
The becquerel (Bq) is the SI coherent unit of radioactivity, defined as exactly one nuclear disintegration per second. Named after Henri Becquerel (discoverer of radioactivity, 1896), it replaced the curie in SI. Household smoke detector ²⁴¹Am sources contain ~30 kBq; a banana contains ~15 Bq of ⁴⁰K. 1 Bq = 1 s⁻¹.
About Megabecquerels
The megabecquerel (MBq) equals 10⁶ Bq and is the standard clinical nuclear medicine unit outside the US. ⁹⁹mTc bone scans use 740 MBq; ¹⁸F-FDG PET scans use 370 MBq; ¹³¹I diagnostic thyroid scans use 185-370 MBq. European and Australian protocols specify all doses in MBq. 1 MBq = 10⁶ Bq.
