Neutron activation
Neutron activation is the process in which thermal neutrons induce radioactivity in matter. The activity (A) follows from the formula:A = σ × n × φ × (1 - e-λ×t)
A = activity (in Bq)
σ = cross section (in m2)
n = number of irradiated atoms
φ = neutron fluence rate (in m-2·s-1)
λ = decay constant (in s-1)
t = irradiation time (in s)
σ = cross section (in m2)
n = number of irradiated atoms
φ = neutron fluence rate (in m-2·s-1)
λ = decay constant (in s-1)
t = irradiation time (in s)
