Complete List of Radiation-Activity Units for Conversion
1 Kilobecquerel [kBq] = 1000.00 Becquerel [Bq]
1 Megabecquerel [MBq] = 1.00000e+6 Becquerel [Bq]
1 Gigabecquerel [GBq] = 1.00000e+9 Becquerel [Bq]
1 Curie [Ci] = 3.70000e+10 Becquerel [Bq]
1 Millicurie [mCi] = 3.70000e+7 Becquerel [Bq]
How this radiation-activity converter works
Becquerel (Bq) is used as the internal base unit. Every value you enter is first converted to Becquerel using exact SI factors, then translated to the requested unit with the same data pulled from the SI Brochure and NIST SP 811.
Key radiation-activity relationships
- 1 Kilobecquerel = 1,000 Becquerel
- 1 Megabecquerel = 1.0000e+6 Becquerel
- 1 Gigabecquerel = 1.0000e+9 Becquerel
- 1 Curie = 3.7000e+10 Becquerel
- 1 Millicurie = 3.7000e+7 Becquerel
Where radiation-activity units are used
Medical physicists, radiation safety officers, and dosimetrists use these radiation units to track exposure, dose, and regulatory compliance. The radiation-activity converter covers real-world units such as Becquerel and Kilobecquerel, giving teams a trusted reference when cross-checking data between labs, suppliers, and regulatory filings.
Tips for accurate radiation-activity conversions
- Always verify the unit symbol in your worksheet—this converter normalizes values through Becquerel, which is the SI reference for radiation-activity measurements.
- When jumping between Becquerel and Kilobecquerel, watch metric prefixes and rounding. A misplaced milli-, micro-, or kilo- prefix can produce errors of several orders of magnitude.
- Document the context (test conditions, instrument resolution, uncertainty) whenever you publish radiation-activity conversions so coworkers and auditors can reproduce your results.
