What does 1 gigabecquerel represent?

One gigabecquerel (GBq) equals 10^9 becquerels, where each becquerel corresponds to one nuclear decay per second.

Why convert gigabecquerels to millibecquerels?

Converting GBq to mBq allows expressing very large radioactivity values in a much smaller unit, useful for precise measurements and comparing with very low activity levels.

Where is the millibecquerel unit commonly used?

Millibecquerel (mBq) is typically used to measure extremely low radioactive activities, such as environmental background radiation or trace contamination.
