In the International System of Units, the derived unit of radioactive activity; the activity of a quantity of radioactive material in which one nucleus decays per second. Symbol: Bq
{i} family name; Antoine Henri Becquerel (1852-1908), French physicist, winner of the Nobel prize in Physics in 1903 (discovered radioactivity in uranium)
Unit of radioactivity, equal to one radioactive disintegration per second Replaces the curie (Ci) : 1 Ci = 3 7x1010 Bq
French physicist who discovered that rays emitted by uranium salts affect photographic plates (1852-1908)
SI unit of radioactivity, defined as one disintegration per second Replaces the Curie
International System of Units unit of activity and equals that quantity of radioactive material in which one transformation (disintegration) occurs per second (1 Bq = 1 disintegration per second = 2 7 x 10-11 Ci)
{i} Bq, International System unit of radioactivity which equals the activity that results from the decay of one nucleus of radioactive or other nuclear transformation per second
The unit used to measure radioactivity 1 Bq equals one disintegration per second This unit replaces the curie (Ci)
a less unwieldy measurement of radioactivity than curies: one disintegration per second (d p s ) A picocurie is 0 037 d p s or 0 03 Bq The most common reporting unit outside the United States for radionuclide air concentrations is µBq/m3 (microbecquerels)
The SI unit of activity equal to one disintegration per second [37 billion (3 7x1010) becquerels = 1 curie (Ci)]
A unit of nuclear activity For example, 1 Bq represents the amount of radioactive substance that disintegrates in one second This unit replaces the curie
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)
The unit of radioactive decay equal to 1 disintegration per second 37 billion (3 7x1010) becquerels = 1 curie (Ci)
The SI unit of activity 1 disintegration per second; 37 billion Bq = 1 curie (See conversion factors in the Measurement section )
This is the SI unit for measuring radioactivity It is defined as 1 disintegration per second
Unit of activity in the International Systemone disintegration per second; 1 Bq = 27 pCi
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 )
The unit of radioactive decay equal to 1 disintegration per second 37 billion becquerels is equal to 1 curie (Ci) There are 30,000 disintegrations per second taking place inside a household smoke detector
born Dec. 15, 1852, Paris, France died Aug. 25, 1908, Le Croisic French physicist. His grandfather, Antoine-César (1788-1878), was one of the founders of the field of electrochemistry, and his father, Alexandre-Edmond (1820-91), made important studies of light phenomena. Henri likewise studied phosphorescent materials as well as uranium compounds and employed photography in his experiments. He is remembered for his discovery of radioactivity, which occurred when he found that the element uranium (in a sample of pitchblende) emitted invisible rays that could darken a photographic plate. His 1901 report of a burn caused by a sample of Marie Curie's radium that he carried in his vest pocket led to investigations by physicians and ultimately the medical use of radioactive substances. In 1903 he shared a Nobel Prize for Physics with the Curies. The unit of radioactivity, the becquerel (Bq), is named for him
