The curie unit (Ci) is based on the activity of 1 g of pure radium-226, which undergoes 3.7 X 1010 transformations per second. It is therefore defined as the quantity of a radioactive isotope which gives 3.7 X 1010 disintegrations per second. The SI unit of activity is the becquerel (Bq), which is equal to one nuclear transformation per second. Hence ... [Pg.200]

Number of curies —units shall be expressed in appropriate curie units, i.e., curies (Ci), millicuries (mCi) or microcuries (pCi) (abbreviations are authorized). For a fissile material, the weight in grams or kilograms of the fissile radioisotope also may be inserted. [Pg.366]

An earlier unit, still in some use, is the Curie unit (abbreviated Ci) defined as ... [Pg.83]

The Curie unit was originally defined as the number of decays per unit time and gram of assuming its half-life to be 1580 y. [Pg.83]

The curie unit is in common use as a measure of disintegration rates. One curie is that quantity of any substance that gives 3.7 X 10 disintegra-... [Pg.433]

The Curie unit (Ci) has been used for radioactive decay unit for many years and is still being used in some cases, but the SI unit, Becquerel (Bq), has practically replaced Curie unit and is the only unit accepted by most scientific publishers. The two are related as follows ... [Pg.8]
