Dosimetric evaluation of a chilled X-Ray irradiator

A new chilled X-ray system for insect irradiation was evaluated dosimetrically. The system was capable of irradiating up to 40 million sterile male mosquitoes per week with a DUR of 1.3 or better. Dosimetry was by GafchromicTM EBT-XD film, scanned at 75 dpi 24 hours after exposure and the color channel information extracted to Excel for processing. Files consist of tiff scans and Excel files of extracted and analysed data, the file names indicate the conditions under which the films were exposed as follows: film sequence number(s) (03-52); -Dnn.n, SSD in cm; -Fl, load flipped over at half exposure time; -R, load rotated, -T|M|B, top, middle or bottom plane of the load; -kVnnn, anode voltage in kV; -Ann.n, anode current in mA; -snnn, exposure time in seconds; -dnn, load depth reduced to, in cm; -r2, load displaced 2 cm right relative to initial exposures. Excel file names include a final component -6|6g indicating that 6 × 6 blocks of pixel values were added to reduce the final resolution to 2mm, g indicating the color channel. File name elements are excluded where they do not apply.

本研究对一款新型冷却型X射线昆虫辐照系统开展剂量学评估。该系统每周可对多达4000万只绝育雄性蚊虫进行辐照，剂量利用率（Dose Utilization Ratio, DUR）不低于1.3。剂量学检测采用Gafchromic™ EBT-XD胶片（Gafchromic™ EBT-XD film），于曝光后24小时以75 dpi分辨率进行扫描，将提取得到的色彩通道信息导入Excel软件进行处理。
本数据集包含TIFF扫描文件与经提取分析后的Excel数据文件，文件名可反映胶片曝光的各项条件，具体规则如下：
- 胶片序列号段（03-52）；
- -Dnn.n：源皮距（Source-to-Surface Distance, SSD），单位为cm；
- -Fl：曝光时长过半时翻转载样台；
- -R：旋转载样台；
- -T|M|B：载样台的顶层、中层或底层平面；
- -kVnnn：阳极电压，单位为kV；
- -Ann.n：阳极电流，单位为mA；
- -snnn：曝光时长，单位为秒（s）；
- -dnn：载样台深度降至指定值，单位为cm；
- -r2：载样台相较初始曝光位置右移2 cm。
Excel文件名末尾包含后缀-6|6g：其中6×6代表将对应像素块求和以将最终分辨率降至2 mm，g代表色彩通道。未适用的文件名元素将被省略。
