Key Features
-
Converts low-level radioactivity units to the SI standard activity unit
-
Supports converting millibecquerel (mBq) to disintegrations/second
-
Useful for environmental monitoring, radiochemistry, and nuclear medicine
-
Provides clear numerical examples to guide users
-
Accessible browser-based interface for quick calculations
Examples
-
Convert 5 mBq which equals 0.005 disintegrations/second
-
Convert 200 mBq resulting in 0.20 disintegrations/second
Common Use Cases
-
Reporting very low environmental radioactivity in air, water, or soil during background monitoring
-
Quantifying trace contamination on laboratory surfaces, equipment, or foodstuffs
-
Characterizing detector background or residual tracer activity in radiochemistry and radioanalytical measurements
-
Specifying the activity of radioactive sources or samples for laboratory or waste assessment
-
Measuring administered activity of radiopharmaceuticals in nuclear medicine
-
Calibrating radiation detectors and instruments
Tips & Best Practices
-
Use this conversion when working with activity levels much smaller than one becquerel
-
Ensure stable decay rates before applying the conversion for accuracy
-
Apply the tool for consistent reporting across different radiation activity measurements
-
Consider measurement uncertainties at extremely low activity values due to detection limits
Limitations
-
Measurement uncertainties may increase significantly at very low activity levels because of detector sensitivity
-
Conversion assumes steady nuclear decay rates and may not be valid if the sample's activity changes rapidly
Frequently Asked Questions
-
What does 1 millibecquerel represent?
-
One millibecquerel corresponds to one thousandth of a becquerel, equating to 0.001 nuclear decays per second.
-
Why convert millibecquerel to disintegrations per second?
-
Converting allows expressing very low radioactivity measurements in the SI unit standard for nuclear decay rate, facilitating consistent comparison.

Can this conversion be used in nuclear medicine?
-
Yes, it is used to quantify administered activity of radiopharmaceuticals and other related measurements.
Key Terminology
-
Millibecquerel [mBq]
-
An SI-derived radioactivity unit equal to one thousandth of a becquerel, used for very low nuclear decay rates.
