The unit of radioactive decay equal to one disintegration per second. The Becquerel is the basic unit of radioactivity used in the international system of radiation units, referred to as the “SI” unit [..]

Is a derived SI unity of radioactivity. 1 Bq one atom per second will decay. Named after Antoine Henri Becquerel.

Unit of activity of a radionuclide named after Henri Becquerel who first discovered radioactivity. Symbol: Bq. The activity is equal to 1 becquerel if 1 nucleus decays per second in the present quanti [..]

The SI unit of measurement of radioactivity, equal to 1 disintegration per second;; 1 Bq = 0.027 × 10-9 Ci.

A modern unit of radioactivity replacing the curie; the activity of an amount of a radioactive material in which one nucleus decays each second.

The SI unit of intrinsic radioactivity in a material. One Bq indicates one disintegration per second and is thus the activity of a quantity of radioactive material which averages one decay per second. [..]

Unit of activity equal to one radioactive disintegration per second. Replaces the older unit, the Curie (Ci): 1 Ci = 3.7x1010Bq.

The unit of radioactive decay equal to one disintegration per second. The Becquerel is the basic unit of radioactivity used in the international system of radiation units, referred to as the SI units. [..]

The Becquerel is a unit used to measure a radioactivity. One Becquerel is that quantity of a radioactive material that will have 1 transformations in one second. Often radioactivity is expressed in larger units like: thousands (kBq), one millions (MBq) or even billions (GBq) of a becquerels. As a result of having one Becquerel being equal to one tr [..]

(Animation) the amount of a radioactive material that will undergo one decay (disintegration) per second. For more information, see “Primer on Radiation Measurement” from CDC.

This is a measure of the activity of a radioactive sample. One Bq means one nucleus decay per second. So a sample with an activity of 12 Bq is undergoing an average of 12 nuclear decays per second.

This is the unit of activity of a radioisotope. It is the number of spontaneous nuclear transformations in one second. The abbreviation is Bq. (The old unit is the curie)

Becquerel (Bq) is the unit in the International System of Units to replace the curie (see curie).

The SI unìt for the radioactivity of a substance that is decaying spontaneously at the rate of 1 disintegration per second. The becquerel replaces the curie (Ci): 1 Bq = 2.7 x 1011 Ci.

Bq; the standard international unit of measurement of radioactivity – corresponding to one decay per second (see also kBq, GBq and TBq). BEIS

One of three units used to measure radioactivity, which refers to the amount of ionizing radiation released when an element (such as uranium) spontaneously emits energy as a result of the radioactive decay (or disintegration) of an unstable atom. Radioactivity is also the term used to describe the rate at which radioactive material emits radiation, [..]

The rate of radioactivity equal to one disintegration per second.

The SI unit for Activity . The Becquerel (Bq) is equivalent to 1 disintegration per second (dps) . Also see the older unit of activity, the Curie .
