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
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
