exposure rate
the quotient of dX by dt, where dX is the increment of the exposure in time dt

X ˙ = dX dt MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiqadIfagaGaaiabg2da9maalaaabaGaaeizaiaadIfaaeaacaqGKbGaamiDaaaaaaa@3AEE@

Note – The SI unit of exposure rate is C kg−1 s−1 (A kg−1). The earlier special units of exposure rate, still in temporary use, were R s−1, R min−1, and R h−1.

débit d'exposition, m
quotient de l'accroissement dX de l'exposition pendant un temps dt par ce temps:

X ˙ = dX dt MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiqadIfagaGaaiabg2da9maalaaabaGaaeizaiaadIfaaeaacaqGKbGaamiDaaaaaaa@3AEE@

Note – L'unité SI de débit d'exposition est égale à C kg−1 s−1 (A kg−1). D'autres unités peuvent être encore utilisées, telles que le R s−1, R min−1, et R h−1 ou d'autres quotients d'unités d'exposition et de temps.
