What is the unit curie used for?
One of three units used to measure the intensity of radioactivity in a sample of material. This value 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.
What is the activity in curie?
The power emitted in radioactive decay corresponding to one curie can be calculated by multiplying the decay energy by approximately 5.93 mW/MeV. A radiotherapy machine may have roughly 1000 Ci of a radioisotope such as caesium-137 or cobalt-60….Curie (unit)

Is curie a unit of radioactivity?
One curie (1 Ci) is equal to 3.7 × 1010 radioactive decays per second, which is roughly the amount of decays that occur in 1 gram of radium per second and is 3.7 × 1010 becquerels (Bq). In 1975 the becquerel replaced the curie as the official radiation unit in the International System of Units (SI).
What is the unit for radioactive activity?
becquerel
The units of measurement for radioactivity are the becquerel (Bq, international unit) and the curie (Ci, U.S. unit).
What does the unit curie measure quizlet?
The units of measure for radioactivity are the curie (Ci) and becquerel (Bq). describes the amount of radiation traveling through the air.
What is the curie used to measure Brainly?
Curie (Ci): Like the Becquerel, the Curie is a unit used to measure radioactivity.
What does the unit Curie measure quizlet?
What is the activity in curie of 1.0 mole of plutonium 239?
5. 513×1011Ci.

What is the unit of radioactivity used to measure activity at a source quizlet?
the masure of the rate at which a radionuclide decays is referred as activity and the SI unit of activity is the Becquerel (bq).
What is a unit of radiation used to measure radiation received by a material?
For example, the amount of radiation being given off, or emitted, by a radioactive material is measured using the conventional unit curie (Ci), named for the famed scientist Marie Curie, or the SI unit becquerel (Bq).
