Response of GAFChromic® HD-V2 film dosimeter in 10-300 Gy dose range for radiation testing of electronic devices

Abstract

The study re ported in this pa per aimed to in ves ti gate the re sponse of a GAFChromic® HD-V2 film do sim e ter in the dose range be tween 10 and 300 Gy, nor mally used to per form ir ra di a tion tests on elec tronic de vices with a 60 Co gamma-ray irradiator. The well-de fined linear ity of re sponse in terms of absorbance as a func tion of ab sorbed dose, eas i ness of han dling and data anal y sis of ir ra di ated do sim e ters, reproducibility, sta bil ity, and in sen si tiv ity to vis i ble light and most of the en vi ron men tal pa ram e ters, make HD-V2 film a flex i ble, in ex pen sive and re li able dose mea sure ment de vice. The study has shown a fog ging ef fect of the do sim e ter response since its value changes over time. Strat e gies and ad e quate pre cau tions to take into account changes on HD-V2 film phys i cal prop er ties for cal i bra tion and rou tine use in in dus trial ap pli ca tions, with a spe cific ref er ence to ra di a tion test ing of elec tronic de vices, have been discussed.Key words: gafchromic do sim e try, HD-V2 film, gamma-ray ir ra di a tion, dose, elec tronic de vice F.

A review of small animal dosimetry techniques: image-guided and spatially fractionated therapy

“…For doses up to 40 Gy, EBT-XD should be used [59]. For FLASH and/or microbeam dosimetry, GAFchromic HD-V2 (Li-PDCA active layer with dominant absorption peaks of 670 and 635 nm) can be used as this film has a dose range between 50 to 1000 Gy and an extremely high spatial resolution of ≤ 5 μm [56,60,61]. Vaiano et al [53] developed a method to use EBT3 film up to 100 Gy with a 4% reading uncertainty for 250 kVp x-rays.…”

Radiochromic Films for the Two-Dimensional Dose Distribution Assessment

“…Today, many RCF types are available, covering a sensitivity dose range from a few mGy to hundreds of kGy; this allows their use in applications from the low dose radiological diagnostic to Quality Assurance (QA) in radiotherapy, brachytherapy up to high dose radiation processing [23][24][25][26]. Because of this versatility and of the aforementioned characteristics, RCFs are used in applications for which an in-depth characterization of the particle beam profile and homogeneity is required, such as in the monitoring of the irradiation for radiation hardness [27][28][29][30][31], as well as in the characterization of charged particle beam lines for radiobiology studies [32][33][34][35]. RCFs are used in the dosimetric characterization of proton and heavy ion beams for hadron-therapy [36][37][38][39].…”
