Abstract AR
تم فحص إمكانية استخدام فلم PMMA بسمك 75µm كمقياس للجرع الإشعاعية الواطئة لأشعة كاما طيفيا، تقع الجرع ضمن المدى (0.1 1mrad-10kard)، و ضمن الطول الموجي الذي يقع ضمن المدى (200-400nm).
أظهرت الأفلام المشععة زيادة في شدة الامتصاصية بازدياد الجرع الممتصة.
رسمت منحنيات المعايرة للتغيرات في الفرق في الامتصاصية عند الأطوال الموجية (218, 301, 343nm).
وجد بأنه عند الطول الموجي (218nm) كانت الاستجابة للجرع خطية عند المدى (10mrad-10krad)، لذا ينصح باعتماده كمقياس للجرع الإشعاعية الواطئة.
Abstract EN
Polymethylmethacrylate film (PMMA) of thickness 75 μm was evaluated Spectrophotometrically for using it as a low-doses gamma radiation dosimeter.
The doses were examined in the range 0.1 mrad-10 krad.
Within an absorption band of 200-400 nm, the irradiated films showed an increase in the absorption intensity with increasing the absorbed doses.
Calibration curves for the changes in the absorption differences were obtained at 218, 301, and 343 nm.
At 218 nm the response for the absorbed doses is a linear in the range 10 mrad- 10 krad.
Hence it is recommended to be adopted as an environmental low doses dosimeter.
