Kerma-rate constant

The quantity kerma rate constant (k) makes it possible to convert becquerel (Bq) to gray (Gy) in the case of radiation from external activity (A):

K = k A t / r²

There are several variants of this quantity, such as dose rate constant (d), ambient dose rate constant (h), and gamma constant (Γ).
