The radiation field from an intense reusable source of flash x-rays that delivers a measured peak dose and dose rate of 370 {plus_minus} 60 krad (CaF{sub 2}) and (3.5 {plus_minus} 0.7) {times} 10{sup 13} rad (CaF{sub 2})/s over a useful area of 80 cm{sup 2} is characterized. CaF{sub 2}:Mn TLDs (thermo-luminescent dosimeters), which are used to measure the dose field, are shown to be dose-rate independent within {plus_minus}15% up to this level. Energy deposition in the CaF{sub 2} TLD chip was analyzed according to the origin of the electrons responsible for that deposition with a new computational tool. 22 refs.
