BS PD CEN ISO/TS 18090-1:2019

This part of ISO/TS 18090 is directly applicable to pulsed X-radiation with pulse duration of 0,1 ms up to 10 s. This covers the whole range used in medical diagnostics at the time of publication. Some specifications may also be applicable for much shorter pulses; one example is the air kerma of one pulse. Such a pulse may be produced, e.g. by X-ray flash units or high-intensity femtosecond-lasers. Other specifications are not applicable for much shorter pulses; one example is the time-dependent behaviour of the air kerma rate. This may not be measurable for technical reasons as no suitable instrument is available, e.g. for pulses produced by a femtosecond-laser.Cross References:IEC 60050-395:2014IEC 61267:2005ISO 4037-2:1997ISO 4037-1:1996ISO 4037-3:1999ICRU 34IEC 60050Incorporates the following:Corrigendum, November 2019
