Becquerel

From Simple English Wikipedia, the free encyclopedia

Becquerel (Bq), equivalent to s-1, is the SI derived unit of radioactivity (A). 1 Bq is defined as the number of times a nucleus decays every second.



where is the number of radioactive atoms in a radioactive sample, which has no unit, and is the decay constant measuring how fast radioactive decay occurs over time, which depends on the nature of the radioactive sample, particularly the constituent isotopes.[1]

Half-life

The half-life is the time required for half of the radioactive atoms of a sample to decay. It can be found by the simple formula

A petabecquerel corresponds to 1015 times a Bq. The unit is named in honor of French physicists Henri Becquerel.
