التحقق من زمن نهاية الأثر النووي باستخدام الكاشف ( CR – 3)

Abstract

The aim of the research is to find the end time of the nuclear effect

using the nuclear impact detector CR-39 where the detector is cut into small square pieces and measuring the thickness of the detector and then the detector is irradiated using alpha particles from the Amritium source Am 241 by using different energy (2.5,3,3.5 )Mev

The time required for scraping is 2 hours using a KOH solution at 6.25 and 70C.

The detector is then washed and the detector thickness is measured after scaling to find the value of the general rate of scraping VB and then measuring the length of the effect Le, which results in measuring the rate of scraping  along the effect VT and finally The end-of-effect time is calculated for each energy  

that was the result of the search both  the length and the effect of the time of the end of the effect increases with energy when there is evidence scraping  and concentration of time.
