The international unit of measure for the quantity of radioactive material; one becquerel is that quantity of radioactive material in which one atom decays in 1 second. One becquerel is equivalent to 27 picocuries.

The standard unit of radioactivity , equal to one nuclear disintegration per second. A becquerel (Bq) is a very small unit and when discussing radioactive waste the term terabecquerel is often more appropriate: one terabecquerel (TBq) = 1012 Bq; ie a million million disintegrations per second.

3/4 The SI unit of radioactivity. One becquerel is equal to 1 nuclear transformation per second. 1 Bq = 2.70 × 10-11 Ci.

abbreviated Bq; 1 becquerel is equal to 1 radioactive disintegration per second

Becquerel (Bq) is the SI derived unit, with a special name, for radioactivity, equal to s-1. It describes a radioactivity of an amount of radionuclide decaying at the rate, on average, of one spontaneous nuclear transition per second. The unit is named after the French scientist A. H. Becquerel (1852-1908) (disintegrations per unit time), equal to s-1.

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)

SI unit of radioactivity; one becquerel is the activity of a quantity of radioactive material in which one nucleus decays per second. Symbol Bq. It is a very small unit and is likely to be used with prefixes such as gigabecquerel (GBq or 109 Bq) or terabecquerel (TBq or 1012 Bq). Named after A. Henri Becquerel who first discovered radioactivity in 1896 in an uranium salt. Replaces the curie (Ci). One curie is equal to 3.7 x 1010 becquerels.

See Units of radioactivity.

The rate of radioactivity equal to one disintegration per second.

a unit by which radiation is measured

a unit for measuring radioactive decay according to the number of atoms that disintegrate in a second

A measurement of radioactivity in a radionuclide. One Becquerel is a rate of one atom disintegrating every second. Named after Henri Becquerel who discovered radiation 100 years ago.

the amount of a radioactive material that will undergo one decay (disintegration) per second. For more information, see " Primer on Radiation Measurement" at the end of this document.

a unit of radioactivity, equivalent to one atomic disintegration per second

the international (SI) the unit for radioactivity in which the number of disintegrations is equal to one disintegration per second. A charged particle emitted from the nucleus of an atom during radioactive decay.

The SI unit of radioactivity, it is equivalent to 1 disintegration per second.

The SI unit of activity equal to one disintegration per second. (1 Bq = 2.7E-11 Ci).

The SI unit of activity equal to one disintegration per second. [37 billion (3.7x1010) becquerels = 1 curie (Ci)].

A unit, in the International System of Units (SI), of measurement of radioactivity equal to one transformation per second.

a unit of activity equal to one disintegration per second.

The International System (SI) unit for activity of radioactive material. One becquerel is that quantity of radioactive material in which one atom is transformed per second or undergoes one disintegration per second.

(Bq) a unit used to measure radioactivity. One Becquerel is the amount of a radioactive material that will undergo one transformation in one second. Often radioactivity is expressed in larger units like: thousands (kBq), or millions (MBq) of becquerels. As a result of having one Becquerel being equal to one transformation per second, there are 3.7 x 1010 (37 billion) Bq in one curie. Curie[] [ Click "BackButton" for previous location

measure unit of radioactivity, corresponding to one disintegration per second

A unit of radioactivity equal to one disintegration per second (1 dps); abbreviated, Bq. A becquerel is approximately equal to 27 picocuries (27 pCi).

The international standard unit of measurement of radioactivity, defined as one radioactive disintegration per second.

Unit of activity in the International System–one disintegration per second; 1 Bq = 27 pCi.

Unit of radioactivity, one disintegration a second. Since this is such a small unit, large multiples are more commonly used: MBq (a million), GBq (a thousand million), TBq (a million million).

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

The SI unit of activity 1 disintegration per second; 37 billion Bq = 1 curie. (See conversion factors in the Measurement section.)

The SI unit of radioactivity. One Becquerel is equal to one disintegration per second.

The SI unit of intrinsic radioactivity in a material. One Bq measures one disintegration per second and is thus the activity of a quantity of radioactive material which averages one decay per second. (In practice, GBq or TBq are the common units.)

is an SI unit of measurement of radioactivity equal to one transformation per second. 1 Bq = 2.7 x 10-11 Ci.

The becquerel (symbol Bq) is the SI derived unit of radioactivity, defined as the activity of a quantity of radioactive material in which one nucleus decays per second. It is therefore equivalent to s-1. The older unit of radioactivity was the curie (Ci), defined as 3.7×1010 becquerels or 37 GBq.
