Definition

differential quotient of the exposure $X$ (exposure <ionizing radiation>) with respect to time (ISO 80000-3: Space and time):

\dot{X} = \frac{d X}{d t}

quotient différentiel de l'exposition $X$ (exposure <ionizing radiation>) par rapport au temps (ISO 80000-3: Space and time) :

\dot{X} = \frac{d X}{d t}

Notes

1 unitsml(C/(kg*s)) = 1 unitsml(A/kg)

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

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

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

1 unitsml(C/(kg*s)) = 1 unitsml(A/kg)

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

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

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