What is successive disintegration?

Suppose a radioactive element A disintegrates to form another radioactive element B which intern disintegrates to still another element C; such decays are called successive disintegration.

How do you derive the decay constant?

Suppose N is the size of a population of radioactive atoms at a given time t, and dN is the amount by which the population decreases in time dt; then the rate of change is given by the equation dN/dt = −λN, where λ is the decay constant.

What is rate of radioactive decay?

The rate of decay, or activity, of a sample of a radioactive substance is the decrease in the number of radioactive nuclei per unit time.

How do you use radioactive decay formula?

Radioactive Decay – Equation – Formula

1. Radioactive decay law: N = N.e-λt
2. (Number of nuclei) N = N.e-λt
3. (Activity) A = A.e-λt
4. (Mass) m = m.e-λt

What is meant by transient equilibrium?

In nuclear physics, transient equilibrium is a situation in which equilibrium is reached by a parent-daughter radioactive isotope pair where the half-life of the daughter is shorter than the half-life of the parent. … Transient equilibrium occurs after four half-lives, on average.

What is meant by radioactive equilibrium?

Definition of radioactive equilibrium : the condition in which a radioactive species and its successive radioactive products have attained such relative proportions that they all disintegrate at the same numerical rate and therefore maintain their proportions constant.

What is meant by disintegration constant?

In most texts the disintegration constant is defined as "the fractional change in number ofatoms which occurs in unit time." This definition is correct only in the limiting case where the unit time interval is in- finitely short. … Its disintegration constant is 0.693/3.825 = 0.18 per day.
