absorbed dose rate
the quotient of dD by dt, where dD is the increment of absorbed dose in time interval dD

D ˙ = dD dt MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiqadseagaGaaiabg2da9maalaaabaGaaeizaiaadseaaeaacaqGKbGaamiDaaaaaaa@3AC6@

Note – The SI unit of absorbed dose rate is joule per kilogram and second, whose special name is gray per second. The earlier special unit of absorbed dose rate, still in temporary use, was the rad per second.

1 Gy • s = 100 rad • s−1 = 1 J kg −1 • s−1

débit de dose absorbée, m
quotient de la dose absorbée dD pendant un temps dt par ce temps

D ˙ = dD dt MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiqadseagaGaaiabg2da9maalaaabaGaaeizaiaadseaaeaacaqGKbGaamiDaaaaaaa@3AC6@

Note – L'unité SI de débit de dose absorbée est le joule par kilogramme par seconde dont le nom est le gray par seconde. L'ancienne unité, encore utilisée temporairement, est le rad par seconde.
