quotient of dH by dt, where dH is the increment of dose equivalent in the time interval of duration dt: = dH/dt NOTE - This quantity is expressed in sieverts per second (Sv/s).the quotient of dH by dt, when dH is the increment of dose equivalent in the time interval dt NOTE - The SI unit of dose equivalent rate is joule per kilogram second, whose special name is sievert per second; sub-multiples, such as µsv • h- 1 , are used in practice. The earlier special unit of dose equivalent rate, still i...
