becquerel

The becquerel (; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as an activity of one per second, on average, for aperiodic activity events referred to a radionuclide. For applications relating to human health this is a small quantity, and SI multiples of the unit are commonly used.

AI overview

A becquerel is the standard unit used to measure radioactivity, defined as one radioactive decay event occurring per second. It's a very small amount for practical purposes involving human health, so scientists typically use larger multiples of the unit instead.
