Secular equilibrium information

In nuclear physics, secular equilibrium is a situation in which the quantity of a radioactive isotope remains constant because its production rate (e...

and vice versa. During reactor operation at a given power level, a secular equilibrium is established within 40–50 hours, when the production rate of iodine-135...
