See the Remarks for absorbed dose.

In report 85a of the ICRU a definition with an equivalent meaning is given as:

The kerma rate, $\dot{K}$ , is the quotient of $d K$ by $d t$ , where $d K$ is the increment of kerma in the time interval $d t$ :

\dot{K} = \frac{d K}{d t} .

1 unitsml(Gy/s) = 1 unitsml(W/kg)

Voir les Remarques en absorbed dose.

Le rapport 85a de l'ICRU donne une définition ayant une signification équivalente:

Le débit de kerma, $\dot{K}$ , est le quotient de $d K$ par $d t$ , où $d K$ est l'incrément du kerma dans l'intervalle de temps $d t$ :

\dot{K} = \frac{d K}{d t} .
