دراسة التوزيع الاحصائي لطيف طاقة السيزيوم Cs-137 باستخدام الكاشف الوميضي NaI(Tl)

Abstract

In this paper, the statistical distribution has been studied the power spectrum of the source of cesium cs-137 irradiated using a reagent fluorescence sodium iodide NaI(Tl) after split its spectrum into areas, shows that the tops are interwoven with each other i.e. there is more than a statistical distribution per curve. It was also noted the presence of more than one top in curved and this is different from bilateral distribution and Poisson distribution and normal distribution which is characterized by the existence of a single top. It was also found that the biggest and the smallest of the spectrum take less space while repeating medium-sized take over number of repetitions .It is also found that the curved settle at some points when the length category (20) period, while continuously changing when the length category (10) period, and there is no symmetry on both sides of the arithmetic average i.e. this distribution differs from the normal distribution. It was reached that the number of overlapping tops increases as the increased length of the category (20) thus, the number of tops more than it is in the case of (10) period. Whenever a big contrast between the spectrum space, the curve is lower and more width, so it is shown that the curves representing the total area differ from those representing the photo top area and net area of the photo top .
