In nuclear physics, secular equilibrium is a situation in which the quantity of a radioactive isotope remains constant because its production rate (due, e.g., to decay of a parent isotope) is equal to its decay rate.

Famous quotes containing the words secular and/or equilibrium:
“but as an Eagle
His cloudless thunderbolted on thir heads.
So vertue giv’n for lost,
Deprest, and overthrown, as seem’d,
Like that self-begott’n bird
In the Arabian woods embost,
That no second knows nor third,
And lay e’re while a Holocaust,
From out her ashie womb now teem’d
Revives, reflourishes, then vigorous most
When most unactive deem’d,
And though her body die, her fame survives,
A secular bird ages of lives.”
—John Milton (1608–1674)
“When a person hasn’t in him that which is higher and stronger than all external influences, it is enough for him to catch a good cold in order to lose his equilibrium and begin to see an owl in every bird, to hear a dog’s bark in every sound.”
—Anton Pavlovich Chekhov (1860–1904)
