Syntax: RADX: DOX={irradiation time} = {delivered dose}/{dose rate} Example: RADX: DOX=0.25 !Dose delivered in 15 minutes (0.25 hour) RADX: DOX=DD1 !Pointer to an array of irradiation times DD1=24 12 1 0.5 0.1 0.001 / !Array of dose delivery times (hour)
Purpose: Set the time required to deliver the radiation dose (baseline exposure scenario) Data Type: real Unit: Gy/hour Default: none Comments: The DOX parameter provides an alternate, sometimes useful, way to specify dose rate. The delivered dose and dose rate are related by {delivered dose} = {dose rate} x {irradiation time}. The values specified by, for example, the AD and ADR or AD and DOX parameters define a baseline exposure scenario. The baseline exposure scenario can then be re-scaled using the OPT and RND keywords. The OPT and RND keywords are used to re-scale split-dose exposures, multi-fraction exposures, and other temporally complex exposure scenarios. For a single dose of radiation delivered at constant dose rate, an array of dose values (e.g., the DD1 array in the above example) can be used in place of the OPT and RND keywords.
