روشی جدید برای اندازه‌گیری پارامترهای چشمه‌های آلفازای فوق اورانیوم

An alpha-gamma coincidence method, using multi-parameter analyzer (MPA) system in list mode was used for measuring parameters of transuranium sources. The benefit of using the list method is preventing duplication of experiments a lot and thus saving the cost and time taken for this type of testing that due to very small sample rate, spend a lot of time. The multi-parameter analyzer stores the coincidence alpha and gamma-ray detector events without the use of specific timing modules, in the form of a list file and the software of MPA construct one and two parameter spectra through the list file. The alpha-gamma coincidence standard test by 241Am source that is often used to demonstrate the effectiveness of these systems was carried out and obtained spectra is reported. As well as demonstrating system performance, the testing of unknown source activities, using alpha-gamma coincidence techniques, is carried out without the need for detection efficiency calibration and the activity of the source is determined to equal 25%.
