Abstract
The radiation field from an intense reusable source of flash X-rays that delivers a measured peak dose and dose rate of 370±60 krad (CaF2) and (3.5 ±0.7)×1013 rad (CaF2)/s over a useful area of 80 cm2 is characterized. CaF2:Mn TLDs (thermoluminescent dosimeters), which are used to measure the dose field, are shown to be dose-rate independent within ±15% up to this level. Energy deposition in the CaF2 TLD chip was analyzed according to the origin of the electrons responsible for that deposition with a new computational tool
