About this radioactive activity converter
Convert radioactive activity between becquerels, curies, rutherfords, and disintegration-based lab units used in nuclear medicine, health physics, isotope work, and radiation safety records.
Activity measures decay rate, not absorbed dose. A becquerel is one nuclear disintegration per second, while a curie is a historical high-activity unit equal to 3.7 x 10^10 Bq.
Units covered
SI activity
Bq, kBq, MBq, and GBq for modern activity reporting.
Clinical and legacy units
Ci, mCi, uCi, and Rutherford for nuclear medicine and older references.
Counting units
dps and dpm for direct lab counter and sample activity work.
How to use it
- Enter the activity value from your source, sample, or reference table.
- Choose the source unit and the unit needed for your report or calculation.
- Use dose-specific converters separately when you need absorbed dose or equivalent dose.
