(PC, pCi) is one trillionth (1 x 10-12) of the amount of radioactivity represented by a curie (Ci). A curie is the amount of radioactivity that yields 3.7 x 10-10 radioactive disintegrations per second (dps). A picocurie yields 2.22 disintegrations per minute (dpm).
A unit for measuring radioactivity related to radioactive decay at approximately two atoms of radon per minute.
a measurement of radioactivity
a unit used to describe the rate of disinitegration of the nucleus of a radioactive element
A unit of amount used in the measurement of radioactive substances. For example, five picocuries of radon are five trillionths of a curie and are equivalent to 11 radioactive radon atoms decaying every minute.
A measure of radioactivity. One picocurie of radioactivity is equivalent to 0.037 nuclear disintegrations per second.
One one-trillionth (1/1,000,000,000,000) of a curie.
One trillionth (10-12) of the amount of radioactivity represented by a curie (Ci). A curie is the amount of radioactivity that yields 3.7 x 1010 radioactive disintegrations per second (dps). A picocurie yields 2.22 disintegrations per minute (dpm) or 0.037 dps.
A unit for measuring radioactivity, often expressed as picocuries per liter (pCi/L) of air.
One pCi is one trillionth of a Curie, 0.037 disintegrations per second, or 2.22 disintegrations per minute.
