Is radiation measured in emissions sec called the curie?

No, radiation is not measured in emissions per second. The curie (Ci) is a unit used to measure the activity of a radioactive substance, representing the rate of radioactive decay. The unit for measuring radiation exposure is the sievert (Sv).


How much is one Ci?

One Curie (Ci) is a unit of measurement used to describe the intensity of radioactivity in a sample. It is defined as the activity of a quantity of radioactive material in which one nucleus decays per second.


What is curie half life?

The curie is a unit of radioactivity equal to 3.7 x 10^10 decays per second. The half-life of a radioactive substance is the time it takes for half of the radioactive atoms to decay. The curie does not have a half-life, as it is a unit of activity, not a property of a specific substance.


What is a curie and becquerel?

A curie is a unit of measurement for radioactivity, equal to the amount of a radioactive isotope that decays at a rate of 3.7 x 10^10 disintegrations per second. A becquerel is the SI unit of radioactivity, equivalent to one disintegration per second.


What is the curie?

It is a unit for measuring radioactive: equivalent to 37 billion disintegrations per second.


What do the curie measure?

The curie is a unit of measurement to quantify the radioactivity of a substance, representing the number of disintegrations per second. It is commonly used to describe the activity of radioactive materials.


What is 100 micro Curie equal to?

A curie is defined as 3.7 x 1010 disintegrations per second. As such, a microcurie is 3.7 x 104 disintegrations per second or, as more commonly stated, 2.2 x 106 disintegrations per minute. In summary, 100 microcuries is 2.2 x 108 disintegrations per minute.


How do you convert count per second to sievert?

You don't A count per second is a measure of how many decays occur within a second. A sievert is a measure of the dose equivalent. This requires knowledge of the isotope, the organism or part of the organism which is receiving the dose, the weight of the organism and the weighting factors which accompany them.


Whose name is used as a unit of measurement of radioactivity of an element?

According to my trusted Random House College Dictionary (copyright 1984), this unit is the curie, named after Marie Curie. One curie = 37.0 billion disintegrations per second.

Which of the following measures the radiation given off by atoms per second?

The unit used to measure the radiation given off by atoms per second is the becquerel (Bq). A becquerel is defined as one radioactive decay event per second.


What is the most commonly used radiation energy unit?

The SI units of energy are Joules but the effects of ionizing radiation are rarely described only by the energy. The pertinent quantities are the activity (number of decays per second), the does (energy deposited per unit mass) and the equivalent dose, a related measure which takes into account the biological effect of exposure on tissues. The SI units for these quantities are the Becquerel, the Gray and the Seivert. The equivalent units of radiation still in use in the United States are Curie, the Rad and the Rem. The Curie or Becquerel is a measure of the ability of a source to produce ionizing radiation measured in the number of decays per second. The Becquerel is equal to one decay per second. A Curie on the other hand is equal to 3.7 x 1010 Becquerels. The Grey is a measure of the energy deposited per kilogram of matter and dependent not only on the number of decays per second but also on the distance to the source and on the ability of any particular type of ionizing radiation to interact with matter. A Grey has units of Joules per Kilogram (100 Rad is equal to 1 Grey). The Grey does not attempt to take into account the biological damage done to different tissues. The Seivert (or rem) is the equivalent dose or the product of the radiation intensity (Grey) and factors which attempt to account for the biological damage done to different tissues by different types of ionizing radiation. While the Sievert has the same base units as the Grey (Joules per Kilogram) they are applied differently and named separately to avoid confusion.
