It was originally defined as "the quantity or mass of radium emanation in equilibrium with one gram of radium (element)", [1] but is currently defined as 1 Ci = 3.7 × 10 10 decays per second [4] after more accurate measurements of the activity of 226 Ra (which has a specific activity of 3.66 × 10 10 Bq/g [5]).
Surface contamination is usually expressed in units of radioactivity per unit of area for alpha or beta emitters. For SI , this is becquerels per square meter (or Bq/m 2 ). Other units such as picoCuries per 100 cm 2 or disintegrations per minute per square centimeter (1 dpm/cm 2 = 167 Bq/m 2 ) may be used.
Specific activity (symbol a) is the activity per unit mass of a radionuclide and is a physical property of that radionuclide. [1] [2] It is usually given in units of becquerel per kilogram (Bq/kg), but another commonly used unit of specific activity is the curie per gram (Ci/g).
The reports say for years Chelyabinsk dumped about 120 million curies of radioactive waste to give you an idea of how much ... The 10 hardest restaurant reservations to book in America. Lighter Side.
One becquerel (Bq) is equal to one disintegration per second; 1 becquerel (Bq) is equal to 60 dpm. [4] One curie (Ci) an old non-SI unit is equal to 3.7 × 10 10 Bq or dps, which is equal to 2.22 × 10 12 dpm. [5]
The Curie is a unit of measurement (3.7 × 10 10 decays per second or 37 gigabecquerels) used to describe the intensity of a sample of radioactive material and was named after Marie and Pierre Curie by the Radiology Congress in 1910. [21] [22]
